About Infertility

Infertility is defined by the World Health Organization as the inability to conceive after more than two years of unprotected intercourse. Worldwide, 10-14% of couples in the reproductive age group face difficulty in conceiving. However, if the woman is more than 35 years old, she should consult an infertility specialist if she has not conceived within a year of trying. Both male and female factors contribute to infertility. About 40% of infertility is due to a male factor, while 40% is due to female issues. The remaining is due to a combination of male and female factors. The main causes of infertility are –

Male Factor

Infertility

  • Poor sperm quality, quantity or both

  • Absent sperm (Azoospermia)

  • Problems with sperm motility

  • Genetic factors

  • Immunological factors

Female Factor

Infertility

  • Blocked Fallopian Tubes

  • Ovulation disorders

  • Endometrosis

  • Pelvic factor

  • Cervical factor

  • Immunological factors

  • Infections

  • Genetic factors

  • Endocrine factors

Diagnosis of Infertility

Before starting any form of infertility treatment, medical examination of both the partners is essential. During the initial consultation we may recommend:

Blood Tests


These aim at checking basic reproductive hormones like AMH, TSH, Prolactin, FSH and LH, Serum Insulin. In special circumstances we may ask for more sophisticated hormonal testing such as Cortisol, DHEAS, Testosterone and 5HT if required.

 Laparoscopy & Hysteroscopy/

Hysterosalpingogram


Laparoscopy and Hysteroscopy: These are surgical procedures which are recommended only if some abnormality in the pelvic organs is suspected.

HSG (Hysterosalpingogram): It is an X-ray which outlines the uterus and fallopian tubes. A dye is injected into the uterus. This will show the contour of the uterus and also tell us if the tubes are patent or not.

Internal Examination & Vaginal Sonography


An ultrasound scan would help us establish the normalcy of the pelvic organs. A gynecological checkup would give us additional information regarding the readiness of the uterus for pregnancy and would also help to diagnose pathological conditions.

Sperm Testing


  • Semen Analysis

Semen analysis is important to rule out male factor as a cause of infertility. A detailed analysis of the count, motility and morphology of the sperm is carried out along with other parameters. We follow the WHO (2010) criteria for assessing semen.

  • Sperm FISH

Sperm FISH is carried out to check if the sperm are genetically normal. Normal sperm are haploid (i.e they have only one set of chromosomes). This test will show us if the sperm are haploid or diploid.

  • Sperm DNA Fragmentation Index (Sperm Apoptosis)

Sperm DNA fragmentation index (DFI) (Sperm Apoptosis) is measured using the TUNEL method to check the percentage of sperm with broken DNA content. Breaks in the sperm DNA can cause slow growth of the embryos and miscarriage and also increases the time to pregnancy.

Available Facilities for Fertility Enhancement

In Vitro Fertilization (IVF)

IVF achieves pregnancy by fertilizing the woman’s eggs (oocytes) outside her body. The oocytes are obtained under mild anesthesia through the vagina using transvaginal guided sonographic procedures.

EMBRYOLOGY LABORATORY
Isolation of oocytes

 

The semen is processed in order to obtain the most healthy sperm. The eggs and sperm are incubated together. Next day, the oocyte is checked for fertilization. The embryos are ready for transfer subsequently. IVF is ideal for couples with tubal blockage or pelvic adhesions, previous tubal sterilization not amenable to reversal and some cases of endometriosis and pelvic factor.

ICSI

In this procedure, the oocyte is prepared by removing its outer coat of cells called the cumulus complex. Once laid bare, the oocyte is held gently by a holding pipette under an inverted microscope. The sperm that has been prepared for microinjection is injected through a very fine micropipette into the cytoplasm (body) of the oocyte. The oocyte holding pipette and the injection pipette are 20 and 60 times thinner than human hair respectively. The egg itself is no bigger than the tip of a pin. The microinjected egg is returned to the incubator and checked the following day for fertilization.

 

Micromanipulation / Intra Cytoplasmic Sperm Injection – Movie Clip

Micromanipulation is ideally suited in cases of very low sperm counts (oligozoospermia) or zero count (azoospermia), very little (asthenospermia) or complete lack of motility and abnormal shape of the sperm (teratozoospermia). Its use is extended to women with advanced age, women suffering from endometriosis and those with immunological and unexplained infertility. ICSI is also performed along with Preimplantation Genetic Testing. Current thinking permits the use of ICSI for many forms of infertility.

 

 

Dr. Firuza Parikh’s team achieved the first ICSI pregnancy in South East Asia in 1994.

Luv Singh is south East Asia’s first ICSI baby.

 

 

 

Intracytoplasmic Morphologically Selected Sperm Injection (IMSI)

This technique has added a new dimension to the procedure of ICSI. Normally the procedure of ICSI is carried out at a magnification that is twenty fold. The IMSI procedure uses a specialized lens which magnifies the sperm seven thousand times. This makes isolation of normal-looking sperm easier. IMSI is particularly useful when there is severe male factor infertility, with a large proportion of abnormal looking sperm, very compromised sperm motility and count and repeatedly failed IVF procedures.

 

CAT Enhances IVF Success at our Centre

 

An innovation developed for the first time in the world by our team has significantly increased the success of Assisted Reproduction (IVF/ICSI). Our technique is known as CAT (Cumulus Aided Embryo Transfer).

 

During a plenary lecture, Dr. Firuza Parikh described the technique “We have harnessed nature to improve pregnancy rates. The embryos are transferred into the uterus along with cumulus cells. These cells surround the oocyte at the time of ovulation. After oocyte retrieval, the cumulus cells are usually discarded. Instead, we allow them to grow in the laboratory as the cells are rich in factors, which facilitate the growth of embryos. At the time of embryo transfer, droplets of cumulus cells are added to the embryos.”

 

The technique was performed in 507 women, more than half of whom had failed IVF attempts in the past. In this group of women, pregnancy rates increased to 46% from 38%.

 

CAT is useful in cases with previous unsuccessful IVF attempts, in older women and in cases where less number of oocytes are obtained. Scientific data on this procedure was published in the prestigious and leading international  Scientific Journal, Fertility & Sterility (Reference “Cumulus coculture and cumulus-aided embryo transfer increases pregnancy rates in patients undergoing in vitro fertilization” Fertil Steril Oct. 2006).

 

Dr. Parikh added that “IVF is not merely a science, it is also a meticulous art. You look into the little details, work with nature instead of trying to outsmart it and always strive towards improving pregnancy rates – CAT is a movement in that direction.”

Percutaneous Epididymal Sperm Aspiration (PESA), Testicular Sperm Aspiration (TESA) and Testicular Sperm Extraction (TESE) are used when there is no sperm in the ejaculate (azoospermia). This can result from an obstruction in the reproductive tract (obstructive azoospermia) or due to lack of sperm production (non obstructive azoospermia). Obstructive azoospermia may be due to failure of the sperm passages to develop, blockage of the tubes transporting the sperm (due to infection or due to surgical blockage of the Vas following male sterilization).

 

PESA/TESA/TESE are minimally invasive surgical sperm retrieval techniques that enable the urologist to recover sperm directly from the epididymis or even the testes of men with obstructive azoospermia so that the sperm can then be used to fertilize eggs by ICSI. The remaining sperm and testicular tissue can be frozen for future attempts.

 

We offer surgical sperm retrieval techniques for men who suffer from azoospermia (no sperm in the ejaculate). Percutaneous Epididymal Sperm Aspiration (PESA) / Testicular Sperm Aspiration (TESA) / Testicular Sperm Extraction (TESE), are procedures in which sperm from men with azoospermia can be removed from the epididymis or the testis and used to fertilize eggs by ICSI. These techniques are utilized in conditions of obstructive and non-obstructive azoospermia.

 

We also perform Micro TESE in men with severe oligospermia or Non-obstructive Azoospermia. This technique is done under an operating microscope.

 

We have one of the largest series in India using testicular and epididymal sperm for ICSI.

 

The Jaslok team had the first pregnancy in India using testicular sperm and ICSI. (Parikh et al., Indian Journal of Urology 1997; 13: 97-98.)

THE DIODE LASERPrior to implantation, the embryo has to escape out of its protective shell known as the zona pellucida by a process known as hatching. If this process is not completed properly, implantation will fail and pregnancy will not occur. We offer Laser technology for Assisted Hatching (LAH), where a laser beam is focused over the zona pellucida making a small opening, between 30-40 microns to facilitate embryo hatching. This technique is particularly useful in women where the embryo has a thick zona and also in women with previous failed cycles and older women where the zona tends to be thick. However, selection of this procedure for the right application is important.

 

Our centre utilizes the Diode laser which is the safest laser in ART. The entire procedure is completed in a few milliseconds. Laser Assisted Hatching is particularly useful for older women (more than 35 years), women with oocytes showing a thick zona and women who have tried IVF unsuccessfully. Laser Assisted Hatching is also carried out during the process of Preimplantation Genetic Testing (PGT).

 

Laser Assisted Hatching : Movie clip

 

We achieved the first pregnancy in India using this technique combined with blastocyst transfer (LAHBT). This facilitates its hatching in the uterus and improves implantation and pregnancy rates. In our published study we have demonstrated pregnancy rates to rise from 19% to 44% in this group of women. (Parikh et al., Indian Journal of Obstetrics and Gynacology. November, 2000.)

 

The diode laser is also used to make an opening in the zona through which a cluster of 5-8 cells called Trophectoderm cells are aspirated at the time of Preimplantation Genetic Testing (PGT).

What is Preimplantation Genetic Diagnosis (PGD) / Preimplantation Genetic Screening (PGS) / Preimplantation Genetic Testing (PGT) / Preimplantation Genetic Testing for Aneuploidy (PGT-A) /  Preimplantation Genetic Testing for Structural Rearrangements (PGT-SR) / Preimplantation Genetic Testing for Monogenic Disorders (PGT-M)?

 

The terms Preimplantation Genetic Diagnosis (PGD) and Preimplantation Genetic Screening (PGS) have been broadly replaced by Preimplantation Genetic Testing (PGT), with different sub-categories. PGT is an early form of prenatal diagnosis. During the ICSI cycle, a few cells called Trophoblast cells are removed (biopsied) from the Day 5 / Day 6 embryo and are checked for genetic abnormalities. The embryos, that are reported normal, are then transferred to the mother’s uterus.

 

Preimplantation Genetic Screening (PGS) also called Preimplantation Genetic Testing for Aneuploidy (PGT-A) is to check for the number of chromosomes and any major gain or loss of genetic material in the chromosome.

 

What are chromosomes?

 

Chromosomes contain the genetic material of the cell. They are present in the nucleus of the cell. Chromosomes comprise of molecules of DNA. Our DNA is organized into small structures called genes. These influence our growth and development. Genes are transmitted from parent to offspring as they are considered to be the basic units of inheritance.

 

Forty six chromosomes are present in all human cells, except the gonadal cells (eggs and sperm). The egg and the sperm each have 23 chromosomes out of which 22 are autosomes and 1 is the sex chromosome. In the egg, the sex chromosome is always X. In each sperm, the sex chromosome can be either X or Y. When the egg and sperm unite at fertilization, the total number of chromosomes becomes 46. Depending on which sperm has fertilized the egg, the embryo becomes either male (XY) or female (XX).

 

In each embryo, chromosomes 1 to 22 are present in 2 copies where one comes from the sperm (biological father) and one comes from the egg (biological mother). Thus, an embryo with 46 chromosomes (22 pairs of autosomes and 1 pair of sex chromosomes) is considered euploid (Normal) embryo.

When the number of chromosomes alters, the embryo is aneuploid (Abnormal). Monosomy occurs when there is loss of 1 copy of the chromosome from the pair. When there is an extra copy present, it is called trisomy of that particular chromosome. When the entire set of 23 chromosomes is extra, it is called triploidy. When both the sets of 23 chromosomes are extra, it is called tetraploidy. If the copy number is more than 4, then it is called polyploidy. If only 1 set of chromosomes (23) is present then it is called haploidyIf more than one cell line is present where one is with 46 chromosomes and other with more or less than 46, it is called as mosaicism. Mosaicism can occur during the embryonic division at any stage.

 

Aneuploidies of embryos can result in spontaneous miscarriages, stillbirths, or developmental disorders in children thus born. The most common aneuploidies are of chromosomes 13, 18, 21, X and Y, followed by aneuploidies of chromosomes 16 and 22.

 

A chromosome translocation is a chromosome abnormality caused by rearrangement of parts of 2 different chromosomes. Translocations can be balanced (an exchange of material with no extra or missing genetic information) or unbalanced (where the exchange of chromosome material results in extra or missing genes and normal functionality is affected). The couples with balanced translocation have a 25% chance of having a child with a normal chromosomal make-up and a 25% chance of having a child with balanced translocation (they are fully functional). There is a 50% risk of having a child with unbalanced translocation which may lead to miscarriage, Intrauterine growth restriction (IUGR), Intrauterine fetal death (IUFD) or delayed developmental milestones.

 

 

What is a Gene disorder?

 

Just like chromosomes come in pairs, most genes also come in pairs, one from the egg and one from the sperm. When, the function of a gene is altered by a change (called a mutation) in the specific sequence of the DNA, a genetic disease results. These mutations can be transmitted in families from generation to generation (inherited), or can be a new change in an individual (de novo). These mutations lead to either single gene or multiple gene disorders.

 

Genetic diseases can be inherited in different ways. A dominant genetic disease is caused by a mutation in one copy of a gene. The risk for a parent with the disease to pass the condition to the child is 50%. e.g. Huntingtons Chorea. 

 

A recessive genetic disease is caused by a mutation in both copies of a gene. A carrier has one normal copy of the gene and one copy with a mutation. Most of them are healthy since having one normal copy is enough to prevent the disease. Two carrier parents have a 25% risk to have a child with the genetic disease. e.g. Thalassemia, Cystic Fibrosis. 

 

Sex-linked genetic diseases are caused by mutations on the X or Y chromosomes. Sex-linked diseases can be dominant or recessive and affect males and females differently. In some genetic diseases, the abnormality in the gene keeps increasing in the next generation and its expression is seen only when an affected child is born. e.g. Fragile X Syndrome. Hence, if there is any history of having an affected child, it is advisable to undergo testing for the next pregnancy and also test the other family members.

 

Preimplantation Genetic Testing is carried out for couples who are at a high risk for various genetic disorders, those with male factor, in advancing maternal age or repeated failed IVF. PGT-M is also done for genetic conditions such as Thalassemia, Sickle Cell Disease, Duchenne Muscular Dystrophy, Leigh Syndrome, Huntington Disease, Neurofibromatosis, Cystic Fibrosis and in Hereditary Cancer Predisposition Syndromes.

 

 

Steps involved in the PGT cycle:

 

For PGT testing, multiple embryos are developed by performing ICSI.

The steps involved in PGT are:

 

  • Pre-PGT work up:

 

For the couple opting for PGT for single gene disorders (PGT-M), it is important to carry out Genetic testing for the disorder in both the partners prior to PGT-M. This determines the mutation (alteration in genetic material) status of both partners. Based on the genetic report, the actual PGT protocol is developed. PGT for single gene disorders (PGD/PGT-M) is carried out only for the known disorder and mutation which is identified for the couple. Other unknown genetic abnormalities cannot be tested at this time.

 

Other important genetic tests for PGT/PGD/PGS:

 

1. Karyotyping : Chromosomal analysis is carried out to check for any aneuploidy or translocation or presence of mosaicism.
2. Sperm FISH to check for percentage of aneuploid sperm. (i.e. sperm with an abnormal number of chromosomes)
3. Sperm DNA Fragmentation Indiex to check for the percentage of sperm with DNA fragmentation.

 

Many routine blood parameters are also tested. Once these reports are ready, the ovarian stimulation cycle begins.

 

  • Hormonal stimulation and oocyte retrieval:

 

The female partner undergoes ovarian stimulation using hormones in order to obtain adequate number of eggs. The eggs are collected under anesthesia.

 

 

  • ICSI/ IMSI:

 

ICSI (Intracytoplasmic sperm injection) is performed. A single sperm is injected into the cytoplasm of the mature egg. After fertilization, the embryo is further incubated in culture up to Day 5/Day 6/Day 7.

  • Embryo biopsy at the Blastocyst stage:

 

For chromosomal aneuploidy screening (PGS / PGT-A), embryo biopsy is generally performed on Day 5 or Day 6 (Blastocyst stage). For single gene disorders (PGD / PGT-M) the embryo biopsy is done on Day 5 or Day 6 (Blastocyst Stage).

 

The Blastocyst is made up of a cluster of cells called the Inner Cell Mass (ICM): which forms the fetus and the trophectoderm cells (which form the placenta). By gentle micromanipulation about 5-8 trophectoderm cells are aspirated into a pipette, loaded into the tube and sent for genetic analysis.

 

 

All of the above steps are carried out in the Embryology laboratory. The trophectoderm cells are then transported to the Genetics Lab for further testing. After biopsy, the embryos are cryopreserved till the day of embryo transfer. 

  • Different techniques of genetic testing include Fluorescence in Situ Hybridization (FISH), Array Comparative Genomic Hybridization (aCGH) and  Next Generation Sequencing (NGS). 
  • Embryo transfer of the genetically normal embryos is carried out in a frozen embryo transfer (FET) cycle and sometimes in the same cycle by doing a quick run analysis.
  • A pregnancy test is performed 14 days later.

 

Please note that our centre does not perform any form of sex determination by PGT in any form.

 

 

Objectives of PGT:

 

  • Prevention of chromosomally abnormal births for couples having a history of failed fertilization after IVF-ICSI, missed abortions or for carriers of balanced translocations
  • To increase the chances of implantation
  • Reducing the incidence of spontaneous miscarriages
  • Reduction in multiple offspring
  • Eliminates the risk of being affected with a familial gene disorder.
  • Savior sibling (HLA matched) to cure a previously affected sibling with cord blood stem cells.

 

 

Risk and Limitations:

 

Even though the benefits of PGT-M/PGT-A are considerable, some risks and limitations have to be kept it mind. This procedure cannot guarantee a healthy pregnancy or eliminate the risk for miscarriage, stillbirth or the birth of a child with an abnormality.

  • If less number of oocytes are retrieved, the ICSI cycle may have to be repeated.
  • Occasionally there may be decreased fertilization, few healthy embryos or embryos that cleave slowly and do not reach the Blastocyst stage. Hence a biopsy may not be possible.
  • If the quality of the embryo is poor, the genetic material present in the biopsied cells may be degraded causing breaks in the cellular DNA. Such DNA material may not give results. In such a case, a repeat trophectoderm biopsy may be needed.
  • It is possible that all the embryos may show genetic abnormalities and hence embryo transfer may not be possible.

 

BLASTOCYST CULTUREA blastocyst is an embryo that consists of more than 100 cells and forms 5 days after fertilization. Using sophisticated culture media, we can select embryos that remain healthy in culture and reach the blastocyst stage prior to transfer. A higher implantation rate has been observed following transfer of blastocysts. Currently our practice is to transfer 1 to 2 embryos at blastocyst stage. The extra embryos are then frozen by vitrification. In case of less number of good quality embryos, a Day 3 transfer of 2 embryos can be performed.

 

We achieved the first pregnancy in India using the technique of Laser Assisted Hatching and Blastocyst Transfer (LAHBT) in 2000.

 

EMBRYO CRYOPRESERVATION / OOCYTE CRYOPRESERVATIONTreatment with ovulation induction at the time of Assisted Reproduction produces many oocytes. We cryopreserve extra embryos for future cycles. Our freezing protocol is by vitrification. All embryos are coded, labeled and stored in special containers to maintain their identity. We have an active oocyte vitrification program. Oocyte cryopreservation is carried out prior to chemotherapy and in women who want to delay childbearing.

 

The process of Vitrification and the process of thawing has to be very precise to ensure survival of the oocytes and embryos.

 

Our IVF Centre has installed the Cryogatt Freezing Susten which is a Safety net for freezing Embryos, Sperm and eggs through Artificial Intelligence so that there is no mixup of samples.

 

We are the first IVF Centre in Asia to have installed this system.

 

All of these biological materials are stored at -196 degrees Centigrade and can be indefinitely stored. The samples are placed in straws or vials that are either bar coded or labelled manually. One has to be very careful that there is no mix up of biological samples. Sometimes the labels can become unsticky. In such cases identification of the biological sample can become difficult. Also the correctly labelled straw has to be identified and removed from the other samples in less than 15 seconds. Any longer exposure can damage the biological material. The Cryogatt System bypasses all these difficulties.

 

How does the Cryogatt System work?

 

The Cryogatt System has Radiofrequency identification that is safe for humans.

 

Each straw is tagged with a RF Identifier (RFID). A platform containing the software program is placed on the rim of the cryostorage tank. As the straw is being removed, the program’s tagging system identifies the straw and the Reader displays the patient’s name ensuring the right sample is being thawed. This also prevents inadvertent thawing of other samples thereby preventing any human error.

 

                

 

There are instances reported where a mixup of Embryos and Sperm have resulted in the birth of biologically unrelated babies.

 

Our system will ensure that this human error does not occur.

 

We currently have more than 13000  eggs and embryos in storage. Our Sperm bank has  6500  samples stored including 900 samples of semen stored for men undergoing chemotherapy.

 

Each container of up to 100 vials or straws can be read in seconds. This can even take place within a freezer or the vapour phase of a Dewar without the need for samples to be individually handled for identification, thus protecting the material from dangerous temperature rise.

 

This system completely eliminates the scope of human error.

 

 

 

DONOR OOCYTE PROGRAMWe have an ongoing program for Oocyte donation for women with premature ovarian failure, surgical or induced menopause and those in the perimenopausal group. Some women with repeated decreased recruitment of follicles at the time of IVF, poor quality of oocytes, high FSH, low AMH, with extensive endometriosis, severe pelvic adhesions and inaccessible ovaries can also avail of this facility. Egg donors are carefully screened and matched with recipients as closely as possible on physical characteristics. They are also screened for sexually transmitted diseases and karyotyping. In case of a genetic mutation in the male partner of the couple seeking Egg Donation, the Oocyte Donor is thoroughly screened for a similar mutation so that the genetic disease is not passed on to the offspring. We ensure complete secrecy and evaluate the background of the donors thoroughly. Donors also undergo a genetic test called Karyotyping in order to ensure that they have normal chromosomes. The family background of the donors is checked for genetic diseases. Advanced genetic testing is done if required. We follow ICMR guidelines for our Donor Egg Programme.

Semen Analysis

A detailed semen analysis is important for assessing Male Factor Infertility. We follow the WHO 2010 guidelines for Semen Analysis. A detailed examination of the concentration, motility and morphology of sperm is carried out along with biochemical examination of the semen. Emphasis is put on examination for pus cells and immature sperm cells.

 

Sperm Processing for Intrauterine Insemination (IUI)

The semen sample is processed by washing, centrifugation and migration. A suitable culture medium is used. The final migration step is done under stringent culture conditions using CO2 incubation. The spermatozoa thus obtained are free of debris and bacteria, are energetic and improve the success rates of intrauterine insemination. We have 2 special rooms with privacy for semen collection. Women with ovulatory dysfunction, previously treated endometriosis with patent tubes, luteal phase defects, cervical factor infertility and polycystic ovarian disease can try IUI first before trying more advanced techniques of Assisted Reproduction. Men with slightly compromised semen parameters may benefit from IUI.

Semen Cryopreservation and Banking 

Donor Insemination ProgramWe routinely have a back-up semen sample frozen for couples who are undergoing treatment in case of inability to give a sample on the day of the IUI, IVF or ICSI. Men undergoing orchidectomy/cancer treatment prior to radiation and chemotherapy can also avail of our cryopreservation facilities. Those undergoing ICSI are encouraged to freeze their sperm so that we have adequate number of sperm at the time of ICSI. We routinely cryopreserve testicular and epididymal sperm, so that repeated attempts at obtaining fresh epididymal and testicular sperm are avoided.

 

Donor Insemination Program

We have a tie up with a sperm bank for donor semen. This has undergone stringent evaluation. The donors are tested for HIV, Hepatitis B and C and VDRL. The semen quality is ensured by following the WHO criteria. The Cryopreservation Donor Semen Program is in accordance with the guidelines established by the Indian Council for Medical Research (ICMR). Karyotyping of the Semen Donor is carried out. Specific Genetic Tests can be performed if requested by the couple.

Recurrent pregnancy loss can be caused by endocrine, immunological, anatomical and genetic factors. Our clinic offers genetic counseling as well as immunomodulation for this condition. We have one of the highest pregnancy rates and live birth rates for women with recurrent pregnancy loss.

 

What is Immunomodulation?

 

A small group of women are prone to repeated miscarriages due to an immunological problem. This can be detected by a test called Immunophenotyping. The test is performed on the endometrial tissue obtained by means of a simple procedure called endometrial biopsy. If the woman has an immunological cause for miscarriage, intravenous therapy with Immunoglobulins is given over a period of time.

 

Some women develop autoantibodies to their pregnancy resulting in repeated pregnancy loss. We have one of the largest series in the world documenting the role of Ovarian Antibodies in causing recurrent miscarriages.

Repeated miscarriage may be caused by sharing of HLA (Human Leucocyte Antigen) between the couple. We have successfully treated such couples to have healthy babies.

 

Genital Tuberculosis:

This is a major factor for female infertility in India. We include a molecular marker test for the TB bacterium using immunocytochemistry along with other tests. This has helped us to detect TB at a very early stage of the disease (latent stage) thereby improving the prognosis of genital TB if detected early.

 

We also offer our patients TB-PCR, a diagnostic test to rule out the involvement of TB as a causative agent for infertility. The test involves obtaining a small amount of tissue from the lining of the uterus since the uterus is a common site for tuberculous involvement, followed by analysis of the sample by Polymerase Chain Reaction (PCR), which is a DNA or RNA based diagnostic tool. This test is specifically recommended for patients with repeated failed ART cycles in the presence of a thin uterine lining. A test called Gene Expert is also carried out to check which antibiotics the TB germ is susceptible to. Culture for TB bacteria is also done.

 

We have scientific documentation of the high incidence of genital TB in Indian women with pelvic factor infertility (Fertility and Sterility, Vol. 67, No.3, 1997, 497-500). The data consists of over 1500 women diagnosed with Genital TB.

Our team of doctors have extensive experience in Laparoscopy and Hysteroscopy procedures. We constantly update ourselves with the latest surgical techniques and are equipped with state-of-the-art surgical instruments. Our team is led by Dr. Neeta Warty who is internationally acclaimed.

 

Laparoscopy is a procedure that allows the doctor to look directly at the uterus, fallopian tubes, ovaries, appendix, and other organs through keyhole surgery. Operative laparoscopy enables the surgeon to correct defects and remove tumors & cysts in the uterus, fallopian tubes and ovaries without the patient undergoing an open surgery. This technique is known as minimally invasive surgery and involves minimal discomfort to the patient. This technique is helpful in the presence of adhesions, endometriosis, pelvic tuberculosis, fibroids, ovarian tumors and cysts and in intestinal conditions such as appendicitis.

 

Our team has one of the largest experiences in the country with operative laparoscopy.

 

Hysteroscopy is a procedure, which allows the doctor to visualize the uterine cavity from within. Operative Hysteroscopy enables the surgeon to correct defects within the uterine cavity. This technique is very helpful to treat intrauterine septum, adhesions and intracavity fibroids.

 

Our team has one of the largest experiences in the country with operative hysteroscopy.

 

Dr Neeta Warty is a pioneer in the field of endoscopy and has performed more than 8000 laparoscopies and hysteroscopies at our IVF centre.

COUNSELINGInfertility and its treatment cause significant stress to the couple. This is detrimental to the reproductive cycle. Before definitive treatment begins, we encourage couples to talk about their stress factors and initiate counseling. We have one of the largest series on psychiatric screening and counseling for ART and many other studies cite our work in this field. Dr. Rajesh Parikh, Consultant Neuropsychiatrist and his team of counsellers will guide you through your cycle.

 

We have counselled more than 10000 infertile couples.

Intrauterine Insemination: IUI

Intrauterine Insemination (IUI) is a fertility enhancing procedure in which sperm from the male partner or from a donor, is washed free of seminal plasma and other debris, concentrated into a small volume of highly motile sperm, and is then injected into the uterus as close to the fallopian tubes as possible, in an attempt to achieve a pregnancy. The purpose of IUI is to increase the number of sperm that reach the fallopian tubes and thus increase the chances of fertilization. IUI provides the sperm an advantage by giving it a head start but still requires the sperm to reach and fertilize the egg on its own. It is a less invasive and less expensive option compared to In Vitro Fertilization.

 

When is IUI used?

 

Male Factor Indications

 

  • Low sperm count
  • Decreased sperm motility
  • Increased numbers of abnormal sperm (abnormal morphology)
  • Disorders of sperm function, e.g., defective egg penetrating ability as determined by laboratory testing (sperm penetration test), where increasing sperm concentration or special processing of the sperm appears beneficial
  • Defects of the penis, e.g., hypospadias or severe penile curvature.
  • Retrograde ejaculation or other forms of ejaculatory dysfunction, e.g. patients with spinal cord injury needing electro-ejaculation.
  • Sexual dysfunction

 

Female Indications

 

  • Poor cervical mucous with a poor post coital test
  • Persistent cervicitis
  • Cervical stenosis
  • Endometriosis
  • Ovulatory dysfunction
  • Psychological or physiological sexual dysfunction

 

Common Indications

 

  • Antisperm antibodies in either male or female
  • Unexplained infertility

 

Indications for Donor IUI

 

  • Azoospermia with spermatogenic failure
  • Previous vasectomy not amenable to IVF/ICSI /TESA/PESA
  • Previous cancer therapy with radiation or chemotherapy.

 

Contraindications for IUI

 

  • Severe male infertility
  • Tubal Disease
  • Mild to moderate endometriosis

 

Fertility Drugs for Intrauterine Insemination (IUI)

 

  • Clomiphene Citrate
  • Gonadotropins
  • IUI can be done in a natural cycle also

 

 

      How does IUI work?

 

Before intrauterine insemination, ovulation-stimulating medications can be used, in which case ultrasound monitoring will be necessary to determine when the eggs are mature. The IUI procedure is performed around the time of ovulation, typically about 24-36 hours after the surge in LH hormone that indicates ovulation will occur soon or 36 hours after the hcg trigger.

The semen sample is washed in the lab to separate the semen from the seminal fluid. A catheter is used to insert the sperm directly into the uterus. This process maximizes the number of sperm that are placed in the uterus, thus increasing the possibility of conception.

The IUI procedure takes only a few minutes and involves minimal discomfort. A pregnancy test is done 14 days after the IUI.

 

Success Rates with IUI

Success rates with IUI are contingent upon the procedure being performed

  1. For the correct indications
  2. Avoiding the performance of IUI when contraindications exist
  3. The age of the woman

 

By and large, birth rates per cycle of IUI performed for the correct indications are reported to be about

 

  • 15% for women under the age of 30
  • 12% for women ages 30 to 35
  • 7% to 8% for women ages 35 to 39
  • Less than 2% for women over the age of 40.

We are seeing an alarming trend of declining AMH and Diminished Ovarian Reserve in Indian women who are seeking infertility treatment. The decline is more noticeable in women in the age range of 30-37 years. This declining trend is creating a generation of young Indian women with Poor Ovarian Reserve (POR), Diminished Ovarian Reserve (DOR), Premature Ovarian Insufficiency (POI) and therefore diminished reproductive potential. In spite of trying various methods of ovarian stimulation, these young women do not respond well to ovarian stimulation and may produce no eggs. For most young women, accepting oocyte donation is not an option. In our experience, use of the Platelet Rich Plasma has shown beneficial effects in Ovarian Rejuvenation. We have introduced a simplified technique of using Intra Ovarian Platelet Rich Plasma (IOPRP) which has shown encouraging results. We have achieved 5 pregnancies with the help of IOPRP in a selected group of 22 women.

 

What does PRP contain?

Platelets are cytoplasmic fragments of megakaryocytes which contain numerous proteins, several growth factors and cytokines stored in the cytoplasmic granules. ADP, ATP, Ca+, Histamine, Serotonin and Dopamine present in the dense granules play an important role in tissue homeostasis. More than 30 bioactive proteins are stored in the alpha granules. Some of these assist in wound healing. Fibrin, Fibronectin, Vitronectin and sphingosine-1-phosphate act as Adhesion molecules. Some of the Growth Factors secreted are the Platelet Derived Growth Factor (PDGF), Vascular Endothelial Growth Factor (VEGF), Transforming Growth Factor beta (TGF-β), Connective Tissue Growth Factor (CTGF), Keratinocyte Growth Factor (KGF), Basic Fibroblast Growth Factor (bFGF), Epidermal Growth Factor (EGF), Insulin-like Growth Factor 1 (IGF-1) & 2 (IGF-2) & Hepatocyte Growth Factor (HGF).

 

What is the function of Platelet secreted growth factors?

Platelet secreted growth factors act on cell proliferation and neoendothelial cell generation. They have rejuvenating properties. These factors are responsible for cell migration and differentiation, cell proliferation, activation of angiogenesis and tissue regeneration, tissue necrosis resolution and  chemotaxis.

 

What are alpha granules:

Alpha granules (α-granules) are a cellular component of platelets. The term “alpha granules” is used to describe granules containing several growth factors such as IGF-1, PDGF, TGF-b and other clotting proteins.

 

What are Dense Bodies:

Dense Bodies (also known as dense granules or delta granules) are specialized secretory organelles. Dense granules are found only in platelets and are smaller than α-granules. The dense granules of human platelets contain substances which are necessary for the several steps of the coagulation.

 

How does PRP works:

Platelets promote healing at the site of injury. PRP promotes wound healing by tissue necrosis resolution, chemotaxis and attract stem cells, cell regeneration, cell proliferation, extra cellular matrix synthesis, remodelling, angiogenesis and epithelialisation. They also have a positive impact on promoting follicle formation, matrix and collagen formation, activation of angiogenesis thus helping in healing, angiogenesis and regeneration. The growth factors in the cells surrounding the eggs control angiogenesis and hence, these activate angiogenesis. The secretory proteins such as PGDF and TGF-β bind to the target cells such as mesenchymal stem cells, osteoblasts, fibroblasts, endothelial and epidermal cells, promoting cellular proliferation, migration, differentiation and osteoid formation. PRP treatment to ovaries enhances ovarian regeneration and reactivates folliculogenesis.

 

How is PRP prepared?

Blood is collected from the woman and centrifuged at different speeds to finally get platelet rich plasma. This amount is mixed with a solution after which it is ready for injection.

 

How is it injected?

For Ovarian rejuvenation, PRP is injected into the ovary. The procedure is carried out under mild anaesthesia using transvaginal ultrasound. About 1.5ml is injected in each ovary.

 

Does IOPRP have any side effects?

No. It does not as the PRP is prepared from the woman’s own blood (Autologus).

 

Does IOPRP injection cause cancer?

No. The growth factors in PRP do not cause granulosa cell tumors or any other form of cancer unlike the risk of granulosa cell tumors after injecting Bone Marrow Derived Stem Cells.

 

 

Our Success

We have carried out embryo transfer in 29 women after IOPRP. Of 27 ET, 3 are pregnant. 2 women have also conceived naturally. Currently a total of 5 women out of 29 who have undergone IOPRP are pregnant.

Intrauterine PRP:

In India, Tuberculosis is a major health problem. The burden of Genital TB is underestimated as most of the patients are asymptomatic. Endometrial TB impairs the lining and decreases the implantation rates. It causes implantation failure by immune modulation of the endometrium and by making the uterine lining non receptive to the embryos.

We have innovated the simplified technique of intrauterine instillation of homologous Platelet Rich Plasma.

Our study has shown a 24% pregnancy rate in women who have not conceived before and who have thin endometrium and history of genital TB. It is also very promising in women who have never conceived before due to endometrial lining issues. Our study also demonstrated a decrease in the rates of ectopic pregnancy following intrauterine instillation of PRP thus explaining its major role in making the uterine milieu conducive to implantation and pregnancy.

How is PRP prepared?

Blood is collected from the woman and centrifuged at different speeds to finally get platelet rich plasma. This amount is mixed with a solution after which it is ready for injection.

 

How is it instilled?

PRP is instilled into the uterine cavity using an intrauterine catheter using sterile precautions.

 

When is it instilled?

PRP is instilled three times during the cycle and is completed before the embryo transfer.

 

How long does the effect of PRP last?

Although this has not been studied, we think that the effect is restricted to the cycle in which it is done.

 

Are the results seen immediately……Same cycle?

Yes.The effects are reflected in the endometrial lining in the same cycle .The positive outcome of pregnancy is the marker of the success.

 

Does IUPRP have any side effects?

No. It does not.

PRP is prepared from the women’s own blood (Autologous).

 

Does IUPRP injection cause cancer?

No. The growth factors in PRP do not cause any form of cancer.

 

Who can benefit from PRP?

  1. Women with failed cycles due to persistent thin lining.
  2. Women not responding to conventional modes for improving the endometrium (Sildenafil/Aspirin/ increased doses of Estradiol Valerate /Intrauterine instillation of GCSF)
  3. Women with history of miscarriages due to endometrial issues.
  4. Women with history of Ectopic pregnancy.
  5. Women with treated genital TB who have never conceived before.

 

Intrauterine PRP should not be used when there is

  1. Active infection of the endometrial cavity.
  2. A high level of CD138 positive cells in the endometrium. This is suggestive of chronic inflammation which should be treated first.
  3. Presence of acute pelvic infection or Pelvic Inflammatory Disease (PID).

FAQs

A woman’s age is a significant factor determining the success of ART. One must also consider that there is an increased risk for birth defects with advanced maternal age. We will need to discuss your case and can help you evaluate and make decisions about these risks. At our center, improved culture techniques, the procedure of Laser Assisted Embryo Hatching and Preimplantation Genetic Testing (PGT) have enabled many women in the age group of 35-43 to have healthy babies. For women around the age of 40, ICSI can be offered with limited success. If PGT is offered along with ICSI and if genetically normal embryos are transferred, then pregnancy rates would increase to around 40-50%. For women aged 43 and above, use of Donor Eggs may be a better option although we have recorded pregnancies in this group when PGT was offered along with ICSI.

In the IVF technique, the oocyte and a calculated number of sperm are placed together in a petri dish in a nutrition-based medium for the fertilization process to take place. However, in cases where the sperm count, motility and morphology are poor, the chances of fertilization with IVF decrease.

In ICSI, a single sperm is directly injected into the cytoplasm of an oocyte. ICSI overcomes problems of low or no sperm count, low or no motility and poor shape of the sperm. ICSI is also helpful in cases of egg problems.

ICSI is the treatment of choice in many conditions such as azoospermia (absence of sperm in the ejaculate). In such situations, ICSI can be performed using sperm retrieved from the testes (TESA or Micro TESA) or the epididymis (PESA). Other indications for ICSI are previous failed fertilization with IVF and when Preimplantation Genetic Testing is offered.

IMSI stands for Intracytoplasmic Morphologically Selected Sperm Injection.

 

In this procedure, the sperm’s image is enlarged 7000 times using a special optical lens. This helps us select sperm which are normal in shape and size and have a normal nucleus (where the genetic material is stored). In our experience the use of IMSI has increased pregnancy rates in Male infertility and in those couples who have had failed ICSI in the past.

 

The IMSI microscope also allows us to inspect eggs at a high magnification so that the quality of the eggs can be assessed better.

An ultrasound scan is a painless procedure using high frequency sound waves to produce an image of the body’s internal organs or the fetus on a television screen. Ultrasound scans are an essential part of all forms of Assisted Reproduction and may be required at various stages of treatment. Scans are used in the preparation of the ovaries and uterus for Assisted Reproduction. For example, the doctor may want to know how the eggs are maturing inside the ovary by measuring the growth of the follicles and will judge the readiness for embryo implantation by measuring the thickness of the uterine lining. One of the reasons for the improvement in the IVF/ICSI procedure is the simplicity of oocyte retrieval by transvaginal ultrasound. In some situations, embryo transfer can be carried out under ultrasound guidance.

The basic steps in an IVF treatment cycle are evaluation and pre-treatment of the couple, ovulation induction, egg retrieval, sperm insemination or sperm injection, fertilization, embryo culture and embryo transfer.

 

(1) Evaluation and Pre-treatment

 

  • Pre-conception counseling: It is very important for a couple to understand the ART procedure. Our team will guide you through the physical and emotional aspects of IVF.

 

  • Anatomic Assessment: A HSG may be recommended. Operative techniques such as laparoscopy and hysteroscopy are sometimes suggested in order to maximize the chances of success.

 

  • Hormonal tests: Baseline TSH, Prolactin, FSH, AMH and LH may be recommended.

 

  • Semen analysis and Semen freezing: Semen Analysis determines whether IVF,  ICSI or IMSI would be the preferred method of fertilization.

 

  • A urology consultation for the male partner is sometimes suggested, in severe male factor infertility.

 

  • We recommend freezing of Semen prior to IVF so that we have a “backup” sample to be used in the event that a fresh semen sample is not available on the day of egg retrieval or ovulation.

 

  • Testing both partners for Infectious Diseases: Screening both partners for infectious diseases like HIV and Hepatitis B & C (that can be transmitted from one partner to another or from mother to fetus) is essential.

 

(2) Ovulation Induction


A woman undergoing IVF/ICSI is given fertility medicines to enhance the growth of the ovarian follicles in order to develop mature eggs.

 

(3) Hormonal Tests & Ultrasound scans


The developing follicles are monitored for their maturity and size through ultrasound and correlated with blood hormone tests like Estrogen, LH and Progesterone.

 

(4) Ultrasound Guided Egg Retrieval


Once the follicles achieve maturity, the next step in the IVF process involves an ultrasound guided egg retrieval. Overnight fasting is required. The procedure is done in a sterile operation theatre under mild anaesthesia. After cleansing the vagina, a fine needle is introduced into the vagina under ultrasound guidance and the ovarian follicles are punctured. Then the follicular fluid is aspirated and checked by the embryologist for the presence of eggs. These are handled gently and quickly transferred to the incubator prior to the IVF/ICSI/IMSI procedure.

 

(5) Insemination of oocytes: IVF/ICSI/IMSI

 

The semen sample is collected in a sterile container and handed over to the lab. It is then processed and prepared to obtain actively motile sperm. The prepared sperm is then used to inseminate the eggs by IVF /ICSI/IMSI in the culture media. For poor quality semen we use microfluidics technology to obtain the best and most viable sperm.

 

(6) A normally fertilized oocyte


The day after egg retrieval and insemination/injection, the embryologist will examine the eggs and check for fertilization. A fertilized egg will have 2 nuclei in the center, one from the egg and one from the sperm.

 

(7) Embryo Culture

 

The fertilized eggs (embryos) will spend about 3-5 days in the laboratory to allow them to develop into the eight-cell or blastocyst stage embryo, at which time the embryo is ready to be transferred into the uterus. We transfer at Day 3 (8 cell stage) or Day 5 (Blastocyst stage) depending on many factors such as the quality of the embryos, the condition of the uterine lining and whether PGT is being done.

 

(8) Laser Assisted Embryo Hatching


Prior to implantation, the embryo has to escape from its protective shell known as the zona pellucida by a process known as Hatching. If this process is not completed appropriately, implantation will fail and pregnancy will not occur. We offer Laser technology for Assisted Hatching (LAH), where a laser beam is focused over the Zona Pellucida making a small opening of about 30 to 40 microns to facilitate Embryo Hatching.

This technique is particularly useful in cases where the embryos have a thick zona and also in cases of previous failed cycles. We have the latest Laser machine which utilises the Diode system. It is considered as the safest Laser application in ART.

 

We have achieved the first pregnancy in India using the Diode Laser in 1999.

 

(9) Embryo Transfer


The resulting embryos are placed back into the uterus with a fine catheter through a simple procedure called embryo transfer. In our centre we perform Cumulus Aided Transfer (CAT) which increases the chances of implantation.

 

(10) Cryopreservation/Embryo Freezing


Most women who undergo hormonal stimulation for an IVF or a related procedure of Assisted Reproduction produce more eggs than needed for transfer during that cycle. The extra eggs or embryos may be frozen or “cryopreserved” and stored for future transfer.

 

(11) After Embryo Transfer

 

Bed rest is not necessary after embryo transfer. Strenuous exercises such as jogging & swimming should be avoided until the pregnancy is confirmed. Otherwise, one can return to regular activities. You can take a regular home-made diet. We recommend avoiding eating papaya and pineapple. Please refrain from sexual intercourse until the BhCG test.

 

(12) A blood Pregnancy test- the BhCG test


This is done 14 days after embryo transfer. We wish you every success in your quest for parenthood!

Success rates for ART procedures are significantly influenced by:

  • The age of the woman
  • The number and quality of eggs produced following ovarian stimulation
  • Quality of the semen
  • The number and quality of embryos formed

 

Pregnancy rates after transfer of a single PGT tested blastocyst are between 40% and 50% at our centre. Chances of pregnancy can be as high as 60% in some cases. The chances of success diminish after 37 years of maternal age. Hence it is very important to try IVF before the biological clock slows down.

As with any medical procedure, the techniques of Assisted Reproduction can be associated with certain risks and complications. These are rarely of a serious nature and can be attended to and treated effectively. The most common are:

 

Ovarian Hyperstimulation Syndrome (OHSS):

 

OHSS occurs when too many ovarian follicles have developed as a result of the ovarian stimulation and is associated with ovarian enlargement and accumulation of fluid in the pelvic cavity. This complication occurs in various degrees of severity in approximately 2.5% of women undergoing IVF treatment. Our team of doctors is highly experienced to treat such a condition, should it arise. We can avoid hyperstimulation if a gnRH agonist called Luprolide is given to trigger ovulation instead of HCG. However in that case, all embryos are frozen and subsequently transfered in the next cycle.

 

Multiple pregnancies:

 

Although many couples are happy at the idea of completing their families quickly if they get twins or multiples through the IVF procedure, bearing twins increases the chances of prematurity and abnormalities in the babies.

The risk of bearing twins can be cut down by placing a single embryo in the uterus. We highly recommend the practice of transferring only 1 PGT tested euploid blastocyst embryo.

Approximately 10% of infertile couples suffer from unexplained infertility. This simply means that the evaluation of the couple has not led to a defined reason for infertility. However, a more thorough search for a cause should be made, since many subtle abnormalities may be discovered to explain the infertility. Usually such problems are due to:

  1. Difficulty in picking up the egg by the fallopian tube
  2. Failure of the sperm to fertilize the egg even when in contact with each other
  3. Failure of implantation of the embryo into the uterus
  4. Presence of local or circulating antibodies
  5. Genetic problems
  6.  Pelvic infection such as genital tuberculosis.

The option is particularly important for older women since it has been shown that as a woman’s age increases, IVF success decreases. Hence women over 40 years have better success with the use of donor eggs and may be suggested this course of treatment. Also women who prematurely reach menopause are candidates for egg donation. Women with decreased ovarian reserve due to previous ovarian surgery & severe endometriosis also qualify. Women with genetic diseases can also avail of donor eggs. A high FSH (>12) and low AMH (≤0.5) may be indicators for the use of donor eggs.

Cumulus cells surround the oocyte (egg) during its maturation in the woman’s ovary. They continue to surround the egg at the time of ovulation. They are embedded in a matrix, which contains hyaluronic acid. Cumulus cells nurture the egg prior to and after ovulation.

In CAT, a few of the feeder cumulus cells on which the embryo is being cultured are transferred along with the embryo into the uterus. We use cumulus cells as a feeder layer over which the embryos are cultured. These cumulus cells are rich in growth factors such as Insulin-like Growth Factor and Vascular Endothelial Growth Factor. These ensure the proper growth of the developing embryos. In order to improve the technique we go a step further. At the time of embryo transfer we add 30 microlitres of the cumulus cells to the embryos so that the nutrients secreted by the cumulus cells continue to be provided within the woman’s body thereby enhancing pregnancy rates.

In IVF, the term “culture” means to grow or incubate embryos in a defined nutrient medium. In the technique of “Co-Culture”, embryos are grown in a culture medium on top of a proliferating monolayer of cells called “Feeder” or “Helper” cells. The feeder cells assist in the growth and development of the embryo.

We have developed a co-culture system which uses the patient’s own cumulus cells. These would otherwise have been discarded at the time of ICSI. We remove them from the oocyte and make them into a layer of feeder cells for the embryos to develop on. Since the patient’s own cumulus cells are more easily available unlike other cells like tubal or uterine cells, they are ideal for use as feeder cells in a co-culture system.
