What is it?
The term ERA stands for Endometrial Receptivity Analysis or Array. In this test, a small sample tissue from endometrial lining (innermost layer of Uterus) is used for evaluating whether the Uterus is ready for implantation of embryo or not.
In the menstrual cycle of a woman the period from 19th to 23rd days is known as “implantation window” during which, the uterus gets prepared for the implantation process. It is part of the luteal phase and the endocrine part of ovaries is producing progesterone. This progesterone brings about modifications in the uterine wall so that, it gets prepared for receiving the embryo. The process involves formation of certain proteins that make the lining thicker and more receptive. In majority of females (84%) this window occurs at the exact time while in very few females (16%) this window occurs either before or after this period.
The IVF treatment in such cases fails as, the embryo transfer is occurring at wrong time. It is happening at the time, when the implantation window is either yet to open or has already been closed. So, the implantation is failing.
When is it prescribed?
It is prescribed in the patients where recurrent implantation failures are observed.

The results demonstrated existence of an endometrial microbiota that is highly stable during acquisition of endometrial receptivity. However, poor reproductive outcomes for in vitro fertilization patients is associated with pathological modification of its profile. This finding provides a novel microbiological dimension to the reproductive process.
How is it done?
Endometrial fluid and vaginal aspirate are investigated for studying the microbial composition. On the basis of these findings distinction was made as a Lactobacillus-dominated microbiota (>90% Lactobacillus spp.) or a non-Lactobacillus-dominated microbiota (<90% Lactobacillus spp.). Although the endometrial microbiota is not regulated hormonally during the acquisition of endometrial receptivity, the presence of a non-Lactobacillus-dominated microbiota in a receptive endometrium was associated with significant decreases in implantation [60.7% vs 23.1% (P = .02)], pregnancy [70.6% vs 33.3% (P = .03)], ongoing pregnancy [58.8% vs 13.3% (P = .02)], and live birth [58.8% vs 6.7% (P = .002)] rates.
When is it recommended?
Uterocervical microbial colonization has been suspected to influence conception rates, with possible causes including an association between cervical microbial species and a pre-existing uterine infection, or colonization of the endometrium or the embryo during transport through the colonized cervix. This kind of microbiota has a significant impact on reproductive outcome even in ART procedures. So, ART failure for no known reason makes it mandatory to examine the Uterocervical microbiota so as to eliminate this as possible reason for ART failures. Thus, the main purpose is to investigate the impact of vaginal microbiome composition on reproductive outcomes within the context of infertility treatments, and the implications this have on assisted reproductive technology procedures.

Pre-implantation Genetic Diagnosis is genetic screening technique which allows an expert to examine the genetic composition of a pre-embryo before it is transferred to the patient’s uterus so that, transmission of hereditary disorders into next generation can be avoided.
Why is it recommended?
A normal human genetic code consists of 23 pairs of chromosomes, and each of the chromosomes may contain hundreds of genes. This genetic material is inherited from gametic cells of both mother and father. The combination of these genes creates the character blueprint for the offspring. Unfortunately, the process may not always work seamlessly. Disorders in the chromosomes or particular gene lead to complications in pregnancy or miscarriage or serious genetic diseases. PGD can help in identification of the issues well before the pregnancy occurs.
In an IVF cycle, the embryos are selected using visual criteria: the embryo or embryos that look healthy are chosen for transfer. Sometimes, a visual inspection is not enough. Some serious genetic abnormalities are invisible to the eye. This is where PGD can be used. Following hereditary abnormalities can be identified with PGD:
When is it recommended?
PGD can be recommended in following conditions:
What are the advantages?
What is it?
It is the genetic study of embryo produced during IVF treatment & can help in having a healthy baby. The technique is helpful to identify embryos with the correct number of chromosomes for successful fertility treatment. PGS is performed on the embryo before it is transferred. This allows the identification & transfer of embryos free from any hereditary abnormalities.
When is it recommended?
It is recommended under following conditions:

What is it?
The embryo formation after fertilization involves a number of stages such as 2 cell, 4 cells, 8 cells stage, Morula and so on. Gradually, the cells become distinct as outer cells (Trophoblast) and inner cell mass (embryonic cells). There is a small cavity in between. This stage is called blastocyst. Usually, the protective covering of embryo (Zona Pellucida) is still intact. The blastocyst hatches out of this covering to get implanted into endometrial lining (Innermost covering of uterus).
Using this blastocyst (developed in laboratory) for embryo transfer in IVF technique is called blastocyst transfer (Blast transfer).
When is it recommended?
Blast transfer is recommended for those patients with one more of the following conditions.
What are the advantages?
What is it?
It is a laboratory procedure where a single sperm is picked up with a fine glass needle and is injected directly into the egg. This is carried out in the laboratory by experienced embryologists using special equipment.
When is it recommended?
It is recommended in any or more of the following conditions.
What are the advantages?
Very few sperms are required for the process and the ability of the sperm to penetrate the egg is no longer important as this has been assisted by the ICSI technique. ICSI does not guarantee that fertilisation will occur as the normal cellular events like fusion of nuclei still need to occur once the sperm has been placed in the egg.
Testicular Sperm Aspiration / Micro Epididymal Sperm Aspiration / Percutaneous Epididymal Sperm Aspiration / Testicular Sperm Extraction
What is it?
It is a method of drawing sperms directly from Testis or Epididymis with a syringe and needle or by a surgical procedure.
When is it recommended?
When the ejaculate does not contain vital sperms one of these methods is recommended.
How is it performed?
PESA AND MESA involve extraction of sperms from Epididymis (a tubular extension of testis). This is done when the Vas Deferens (duct that carries sperms away from testis for being ejaculated) is impaired. In the event of the PESA method the sperms are aspirated together with the fluid from epididymal ducts with a fine needle directly through the skin of scrotum. In MESA method a small microsurgical skin incision is performed, a puncture needle is inserted via this incision and the fluid is aspirated. The fluid is immediately analyzed in an embryology laboratory.
TESE
If sperms can not be obtained by MESA method, TESE is performed. In TESE, sperms are obtained directly from the testicular germinal epithelium. Tissue samples are taken from small incisions in the outer testicular layer and are analysed in the embryology laboratory to confirm presence of sperms in the aspirated fluid.

MACS is a technique which allows the spermatozoa with the best characteristics to be selected for use in Assisted Reproduction Treatments. This technique removes apoptotic (those which will disintegrate without achieving fertilisation) spermatozoa and helps select the healthy ones, thus increasing the possibility of pregnancy.
How is it done?
When is it recommended?
This technique can be used with any kind of patient who opts for ART, but is mainly used with:
What is it?
It is a test performed with fresh ejaculate received from the patient. This is an effective method for measuring DNA damage in thousands of sperm in the ejaculate. It measures the susceptibility of sperm DNA to denaturation process such as exposure to heat or acids. After this exposure sperms are stained with a fluorescent probe (dye) that interacts with the DNA molecule. Then quantitative analysis made about sperms with fragmented DNA.

What is it?
Endocrine glands in the body are responsible for secretion of hormones which are carried through blood and regulate functioning of different body systems. Fluctuations in levels of these hormones can lead to physiological disorders.
What are they?
How are they significant in fertilitiy?
Hormone imbalance can lead to various issues that may affect the fertility and cause issues as follows:
How is it diagnosed?
Following conditions indicate possibility of hormonal imbalance.
What is it?
Human immune system is capable of identifying and destroying invading microbes or foreign cells. This mechanism involves participation by certain specialized cells called Lymphocytes. The immunity present right from birth is innate immunity in which Natural Killer Cells play a significant role. These are different from the cells that protect our body from infections. NKCs are able to identify own body cells from foreign cells. During pregnancy the foetus in formation has both maternal and paternal combination of chromosomes and there is possibility of tissue conflict because the growing embryo or foetus is nourished through placenta. Uterine wall releases natural killer cells at the time of pregnancy. These cells some times identify placenta or embryonic cells are foreign cells and are likely to attack them. Usually rate of their synthesis increases during menstruation but diminishes and stops at the time of delivery.
If in their number does not decline, then there is possibility of miscarriage. Corrective measures are required in such conditions.
How is it done?
Either by conducting blood analysis and investigating activation level of the killer cells or by extracting and investigating tissue of uterine wall it is possible to diagnose the problem and suitable treatment like suppressing immune response or prescribing appropriate hormone therapy can overcome this problem.
When is it recommended?
If the patient has a history of repeated miscarriages and investigation reveals the causative factor as Uterine Natural Killer Cells, above said treatment is recommended.
What is it?
This is a condition in which the defense mechanism of the body starts identifying normal body cells are foreign cells and starts destroying them. In short, the immune system has been misguided against own body cells and can lead to serious consequences. This kind of disorder can affect endocrines, muscles, digestive system or gonadal organs (Testis or Ovary). Effects on endocrines or gonadal organs can result into infertility. Immunity against ovary minimized the ovarian reserve.
How is it diagnosed?
Autoimmune disease affecting ovary can be diagnosed by checking the ovarian reserve. This is done by analyzing the levels of FSH (Follicle Stimulating Hormone) and AMH (Anti Mullerian Hormone) in blood. Abnormally excess values of these hormone for a particular age could be due to reduced ovarian reserve and is likely to cause early menopause or infertility.
What are various autoimmune diseases?
Thyroid disease: Thyroid gland plays very important role in most of the body activities. Its autoimmunity in women, can reduce the pregnancy rate and can lead to miscarriage.
Anti-sperm Antibodies: Some times in men, antibodies are generated against own sperms. This may reduce the number or motility of sperm and reduce the chances of fertilization in female partner. The men who have had history of testicular trauma or surgery, reversal of vasectomy or treatment for varicocele are likely to have this type of antibodies.
Antiphospholipid Antibody Syndrome: This is a disorder in which antibodies are generated against a particular component of placental tissue resulting into miscarriage, certain pregnancy complication or placental abruption.
How is it treated?
Once diagnosed, the particular disease can be treated with appropriate medication and possibility of conception can be increased. Specific fertility treatment can provide a respite.
What is it?
Some times, hereditary factors could be responsible for infertility. In such cases before recommending any line of treatment, it is necessary to diagnose the cause of infertility. Studying the genetic or chromosomal composition of the concerned patient to rule out the genetic factor is done in Karyotyping.
PGD (Preimplantation Genetic Diagnosis) involves using one of the embryonic cell for kayotyping. If any defect is detected such embryos can be discarded and healthy embryos can be used for implantation.
Every normal body cell except Red Blood Cells has a set of 46 chromosomes (23 pairs) in its nucleus. These chromosomes are received from both the parents. These can be arranged in 23 pairs out of which the 23rd pair (Sex chromosomes or heterosomes) defines sex of the individual while other 22 pairs (somatic chromosomes or autosomes) of chromosomes define other body characters. Various units of heredity (genes) are located on these chromosomes. In karyotyping technique the integrity of chromosomes can be identified and any aberration in them can be detected. This can give an insight about any congenital abnormality that can result in the child to be born.
How is it done?
When is it recommended?
Karyotyping is recommended under following conditions so as to define the genetic anomaly and prevent it from being passed on to next generation.
What are the advantages?
In routine IVF technique, usually a healthy sperm participates in fertilization but, if ICSI is carried out even an unhealthy sperm can be used for fertilization.
Intake of proper food becomes very important during the fertility treatment. Eating certain foods during different phases of your menstrual cycle can enhance the fertility. So, if a woman wants to maximize her chances of conceiving, it is possible to eat foods that have advantageous to each phase. So, we ask our experts to weigh in on what to actually eat during each of the reproductive phase.
The list includes:
1. Plenty of fruits and vegetables
2. Complex carbohydrates – whole grains like brown rice , oats and whole meal bread .
3. Organic food where possible.
4. Oily foods like nuts, fish and oil.
5. Add lemon , pomegranate, green leafy vegetables and tomatoes to diet .
6. Flax seeds + sunflower seeds .
7. Avoid trans fats.
8. Increase intake of fibre.
9. More fish and organic eggs than red meat .
10. Avoid additive ,preservatives and artificial sweetner.
11. Reduce and avoid sugar both on its own and hidden in food .
12. Avoid caffeine : coffee, chocolate ,tea ,cola & alcohol .
13. Avoid processed food.
14. Try having fresh and home-made food.
What is it?
It is avoiding weight gain or losing weight for improving the chances of conceiving. Too low or too high body weight can interfere with fertility of an individual and hence, needs to be managed appropriately.
How is it done?
Normally, weight loss management involved diet and exercise. The couple trying for pregnancy needs to take careful measures in this. Proper diet and moderate exercise are best recommended for weight loss. But during pregnancy if necessary, weight management must be done preferably by diet control. Heavy exercise can affect the embryonic development in uterus and hence, has to be avoided.
When is it recommended?
Excess body weight in female partner is known to reduce the possibility or pregnancy. There is a need to manage the weight appropriately for natural pregnancy or even IVF. When an obese patient approaches for IVF treatment, before treatment the patient needs to undergo weight management regime and only then the IVF protocol can be followed. As mentioned above, the weight loss should be by controlled diet and not entirely by exercise.
What is it?
It’s the plasma separated selectively from peripheral venous blood and enriched with activated platelets.
How is it done?
When is it recommended?
The women with one of more of the following issues are recommended this treatment.
What is it?
Sometimes, female partner’s blood identifies lymphocytes from male partner as immunogens and reacts to them. In such cases, an aspect of immune-compatibility occurs leading to difficulty in conceiving. Active Immunotherapy can be an appropriate solution in such patients wherein, this type of immunity is suppressed and then ART can be tried.
When is it recommended?
Recurring miscarriages in a patient could be due to immune response by female partners blood to male partner’s lymphocytes. In such cases, after confirming cause of miscarriages as immune response immunotherapy can be recommended.
How is it done?
The blood from concerned patient is drawn and tested for confirming its reaction with male partner’s blood sample. If the cause is identified as immunity, immunotherapy is started.
