At RMA, once the embryos reach the blastocyst stage, they are tested through a process called Preimplantation Genetic Testing for Aneuploidy (PGT-A), which lets doctors know which embryos have a normal number of chromosomes. While genetically normal embryos are much more likely to lead to pregnancy and healthy babies, the transfer of abnormal embryos will either result in no pregnancy, miscarriage, or an affected baby. While testing is occurring on a small part of the embryos, the embryos themselves are frozen, awaiting a receptive uterus. A large, prospective study performed recently at RMA confirmed that performing an embryo biopsy does not harm the embryo and does not decrease the likelihood of implantation.


Our team here at the Center for Human Reproduction has recently developed an infographic explaining one of the most common causes of female infertility: unexplained infertility. This diagnosis is given to 30% of infertility cases and yet, we believe it really is a non-diagnosis. In our clinical experience, with proper testing, up to 90% of unexplained infertility diagnoses can be attributed to treatable causes.
With the exception of severe male infertility, 70% of the oocytes will become fertilized. In the case of severe male infertility, ICSI (pronounced ick-see) may be used to fertilize the eggs, instead of simply placing them in a culture dish. With ICSI, the embryologist will choose a healthy-looking sperm and inseminate the oocyte with the sperm using a special thin needle.

Oral drugs used to stimulate ovulation include clomiphene citrate and aromatase inhibitors. While taking these drugs, you will be monitored to see if and when ovulation occurs. This can be done by tracking your menstrual cycle or with an ovulation-predictor kit (an at-home urine test). You may be asked to visit your doctor for a blood test or ultrasound exam.


If a man and woman 35 or younger have had unprotected sex for at least 12 months (or six months if older than 35) without getting pregnant, they should suspect secondary infertility. This especially applies to women older than 30 who have experienced pelvic inflammatory disease, painful periods, irregular menstrual cycles or miscarriages, and to men with low sperm counts.
Assisted hatching. About five to six days after fertilization, an embryo "hatches" from its surrounding membrane (zona pellucida), allowing it to implant into the lining of the uterus. If you're an older woman, or if you have had multiple failed IVF attempts, your doctor might recommend assisted hatching — a technique in which a hole is made in the zona pellucida just before transfer to help the embryo hatch and implant. Assisted hatching is also useful for eggs or embryos that have been previously frozen as the process can harden the zona pellucida.

Availability of IVF in England is determined by Clinical commissioning groups. The National Institute for Health and Care Excellence recommends up to 3 cycles of treatment for women under 40 years old with minimal success conceiving after 2 years of unprotected sex. Cycles will not be continued for women who are older than 40 years old.[156] CCGs in Essex, Bedfordshire and Somerset have reduced funding to one cycle, or none, and it is expected that reductions will become more widespread. Funding may be available in "exceptional circumstances" – for example if a male partner has a transmittable infection or one partner is affected by cancer treatment. According to the campaign group Fertility Fairness at the end of 2014 every CCG in England was funding at least one cycle of IVF".[157] Prices paid by the NHS in England varied between under £3,000 to more than £6,000 in 2014/5.[158] In February 2013, the cost of implementing the NICE guidelines for IVF along with other treatments for infertility was projected to be £236,000 per year per 100,000 members of the population.[159]

Nadya Suleman came to international attention after having twelve embryos implanted, eight of which survived, resulting in eight newborns being added to her existing six-child family. The Medical Board of California sought to have fertility doctor Michael Kamrava, who treated Suleman, stripped of his licence. State officials allege that performing Suleman's procedure is evidence of unreasonable judgment, substandard care, and a lack of concern for the eight children she would conceive and the six she was already struggling to raise. On 1 June 2011 the Medical Board issued a ruling that Kamrava's medical licence be revoked effective 1 July 2011.[116][117] [118]


For cases where donor sperm is required, the majority of patients use commercial sperm banks as their source of donor sperm. You can find out a lot about a potential donor before making your choice. For example, you can access information about the donor’s ethnic or racial background, education, and physical characteristics. It’s also reassuring to know that sperm banks always screen donors for sexually transmitted diseases (STDs) such as chlamydia, syphilis, gonorrhea, hepatitis, HIV, and others. The FDA and the Centers for Disease Control and Prevention (CDC) recommend that frozen semen from a licensed sperm bank be used in order to prevent STDs.
Fertility expert Zita West has noticed this increase at her London clinic. "The main reason," she explains, "is age. Women are having babies later." Exhaustion also plays a part. "The sleeplessness of life with a small child can't be underestimated," she says. "You might still be breastfeeding, you might be sharing a bed with a toddler, you might be holding down a job at the same time. Basically, there's not a lot of sex happening."
Mild IVF[64] is a method where a small dose of ovarian stimulating drugs are used for a short duration during a woman's natural cycle aimed at producing 2–7 eggs and creating healthy embryos. This method appears to be an advance in the field to reduce complications and side-effects for women and it is aimed at quality, and not quantity of eggs and embryos. One study comparing a mild treatment (mild ovarian stimulation with GnRH antagonist co-treatment combined with single embryo transfer) to a standard treatment (stimulation with a GnRH agonist long-protocol and transfer of two embryos) came to the result that the proportions of cumulative pregnancies that resulted in term live birth after 1 year were 43.4% with mild treatment and 44.7% with standard treatment.[65] Mild IVF can be cheaper than conventional IVF and with a significantly reduced risk of multiple gestation and OHSS.[66]
The penetration of the IVF market in India is quite low at present with only 2,800 cycles/million infertile women in the reproductive age group (20–44 years) as compared to China which has 6,500 cycles. The key challenges are lack of awareness, affordability and accessibility.[152] India in 2018 becomes the destination for Fertility Tourism because of most affordable IVF treatment cost. IVF treatment cost in India varies from $2000 to $4000 (roughly between 150000/- INR to 250000/- INR including all aspects of IVF treatment with medicines which is almost 5 times lower than IVF Cost in Western part of the world.
1. Changes to Your Menstrual Cycle: This may be an absence of your period, heavier than normal flow or irregular menstrual cycles may be signs of infertility. Consider tracking your menstrual cycle to help you identify patterns or changes early on. This will also be helpful in case you ever seek guidance from a physician, as he or she will inquire about your medical history.

Time. The factor of time cuts both ways when you are weighing up these two options. IUI is a much shorter process than IVF, so if your first cycle is successful, it could be the quickest route to bringing home a baby. However, because of the gap in success rates between the two treatments, some patients in their late 30s to early 40s may get pregnant faster by going directly to IVF rather than waiting until they have had several failed IUI cycles.
In order for pregnancy to happen, sperm has to meet the egg. This normally takes place at the end of the fallopian tube, and this is called fertilization. There are a number of obstacles that can prevent this from happening, and the process itself even in healthy young fertile women is very complex- hence the low pregnancy rate each month. Obstacles such as cycle timing, low sperm count, poor sperm motility, blocked fallopian tubes, or endometriosis must be overcome to achieve a pregnancy. Timing is often the most common obstacle to conception. What does it mean for you when common causes of infertility are ruled out and you’re told you have unexplained infertility? It should mean a time of hope.
