Certain kinds of IVF, in particular ICSI (first applied in 1991) and blastocyst transfer (first applied in 1984) have been shown to lead to distortions in the sex ratio at birth. ICSI leads to slightly more female births (51.3% female) while blastocyst transfer leads to significantly more boys (56.1% male) being born. Standard IVF done at the second or third day leads to a normal sex ratio.
Undergo minor surgery to retrieve eggs. Following a round of injections, your doctor will determine the best date to retrieve eggs from the follicles of your ovaries. If you choose to use donor eggs, the retrieval process will occur with the donor, or the frozen eggs may be collected and used. A partner’s sperm or donor sperm will also be collected.
Generally, the best chance of pregnancy is when sex happens 1-2 days before ovulation. If you have a regular 28-day cycle, count back 14 days from when you expect your next period to start. Plan on having sex every other day around that time -- say, days 12 and 14.  Keep in mind that having sex every day may lower a man's sperm count. Your cycle may be longer or shorter, so an online ovulation calculator may help you figure out the likely day.
Fertility is often something people do not consider until they are actively trying to start a family, or in many cases after they have started having trouble conceiving. What many don’t realize is that couples ages 29-33 with normal functioning reproductive systems only have a 20-25% chance of conceiving in any given month. Add in any number of infertility factors from either gender and those chances can decrease significantly.

The Latin term in vitro, meaning "in glass", is used because early biological experiments involving cultivation of tissues outside the living organism were carried out in glass containers, such as beakers, test tubes, or Petri dishes. Today, the scientific term "in vitro" is used to refer to any biological procedure that is performed outside the organism in which it would normally have occurred, to distinguish it from an in vivo procedure (such as in vivo fertilisation), where the tissue remains inside the living organism in which it is normally found.


Most couples develop a willingness to conceive a child at some point in their life. Generally, couples conceive within the first year, and around 7% of couples conceive in the second year. The inability to conceive within 12 months is defined as infertility. It is recommended to seek help from a reproductive endocrinologist if you are unable to conceive within 12 months. Our modern technology in healthcare has opened a lot of options for women who are facing infertility issues.

"Demographers tend to define infertility as childlessness in a population of women of reproductive age," whereas "the epidemiological definition refers to "trying for" or "time to" a pregnancy, generally in a population of women exposed to" a probability of conception.[8] Currently, female fertility normally peaks at age 24 and diminishes after 30, with pregnancy occurring rarely after age 50.[9] A female is most fertile within 24 hours of ovulation.[9] Male fertility peaks usually at age 25 and declines after age 40.[9] The time needed to pass (during which the couple tries to conceive) for that couple to be diagnosed with infertility differs between different jurisdictions. Existing definitions of infertility lack uniformity, rendering comparisons in prevalence between countries or over time problematic. Therefore, data estimating the prevalence of infertility cited by various sources differs significantly.[8] A couple that tries unsuccessfully to have a child after a certain period of time (often a short period, but definitions vary) is sometimes said to be subfertile, meaning less fertile than a typical couple. Both infertility and subfertility are defined as the inability to conceive after a certain period of time (the length of which vary), so often the two terms overlap.
A 2013 review and meta analysis of randomised controlled trials of acupuncture as an adjuvant therapy in IVF found no overall benefit, and concluded that an apparent benefit detected in a subset of published trials where the control group (those not using acupuncture) experienced a lower than average rate of pregnancy requires further study, due to the possibility of publication bias and other factors.[34]
In 2008, a California physician transferred 12 embryos to a woman who gave birth to octuplets (Suleman octuplets). This led to accusations that a doctor is willing to endanger the health and even life of women in order to gain money. Robert Winston, professor of fertility studies at Imperial College London, had called the industry "corrupt" and "greedy" stating that "one of the major problems facing us in healthcare is that IVF has become a massive commercial industry," and that "what has happened, of course, is that money is corrupting this whole technology", and accused authorities of failing to protect couples from exploitation: "The regulatory authority has done a consistently bad job. It's not prevented the exploitation of women, it's not put out very good information to couples, it's not limited the number of unscientific treatments people have access to".[101] The IVF industry has been described as a market-driven construction of health, medicine and the human body.[102]

Progesterone elevation on the day of induction of final maturation is associated with lower pregnancy rates in IVF cycles in women undergoing ovarian stimulation using GnRH analogues and gonadotrophins.[23] At this time, compared to a progesterone level below 0.8 ng/ml, a level between 0.8 and 1.1 ng/ml confers an odds ratio of pregnancy of approximately 0.8, and a level between 1.2 and 3.0 ng/ml confers an odds ratio of pregnancy of between 0.6 and 0.7.[23] On the other hand, progesterone elevation does not seem to confer a decreased chance of pregnancy in frozen–thawed cycles and cycles with egg donation.[23] 

People who have suffered primary infertility tell me that the only way they can get by is to avoid everything and anything to do with babies. But for the secondary infertility sufferer, this is not an option. You are confronted on a daily basis at the school gates by pregnant women, people with babies, large families squashed into multiple buggies. School drop-off becomes a terrible tableau of everything you want but cannot have.
All pregnancies can be risky, but there are greater risk for women who are older and are over the age of 40. The older the women the riskier the pregnancy. As women get older, they are more likely to suffer from conditions such as gestational diabetes and pre-eclampsia. If older women do conceive over the age of 40, their offspring may be of lower birth weight, and more likely to requires intensive care. Because of this, the increased risk is a sufficient cause for concern. The high incidence of caesarean in older mothers is commonly regarded as a risk.
3-6 months of treatment with Clomid pills (clomiphene citrate) might improve fertility by as much as 2 times as compared to no treatment. This is a very low level infertility treatment. Infertility specialists do not usually recommend Clomid treatment( without insemination) for unexplained infertility for women over the age of about 35. Most fertility specialists do not use it (without IUI) on any couples with unexplained infertility. If a woman is already having regular periods and ovulating one egg every month, giving Clomid, which will probably stimulate the ovaries to release 2 or 3 eggs per month (instead of one) is not really fixing anything that is broken - and is not likely to be successful.

Coping with secondary fertility can be tough. Endless doctor appointments, tests, procedures, and medications. Sleepless nights. Time and energy away from your little one. Guilt over wanting another pregnancy when many women are struggling to have just that. Stress between you and your partner. Sadness when you get invited to yet another baby shower — and guilt for even feeling that way.

IVF: During IVF, medications are usually taken for around 10 days to grow a large number of eggs. Once many eggs have developed, a procedure takes place where the eggs are removed from the ovaries. The eggs are then fertilized outside of the body in a lab. After growing for a few days in the lab, an embryo is transferred back into the woman’s uterus. 
In IUI, this natural sequence of events is given some assistance. A sample of sperm is prepared in the laboratory so that only the best moving sperm are concentrated together. This sperm is then deposited directly into the uterus without having to swim there on its own, which can be challenging, especially if the sperm do not swim well. IUI places a higher concentration of moving sperm closer to the ovulated egg. Often a woman will have taken medication prior to the IUI procedure to ensure she will ovulate around the time of the procedure, so egg and sperm can meet.

The Rand Consulting Group has estimated there to be 400,000 frozen embryos in the United States in 2006.[83] The advantage is that patients who fail to conceive may become pregnant using such embryos without having to go through a full IVF cycle. Or, if pregnancy occurred, they could return later for another pregnancy. Spare oocytes or embryos resulting from fertility treatments may be used for oocyte donation or embryo donation to another woman or couple, and embryos may be created, frozen and stored specifically for transfer and donation by using donor eggs and sperm. Also, oocyte cryopreservation can be used for women who are likely to lose their ovarian reserve due to undergoing chemotherapy.[84]
Deciding whether to undergo in vitro fertilization, and how to try if the first attempt is unsuccessful, is an incredibly complicated decision. The financial, physical, and emotional toll of this process can be difficult. Speak with your doctor extensively to determine what your best options are and if in vitro fertilization is the right path for you and your family. Seek a support group or counselor to help you and your partner through this process.

In order to have a successful IVF pregnancy, the first few weeks need special care. When you undergo IVF, you will be continuously monitored throughout the process by skilled doctors. Constant supervision reduces the complications associated with pregnancy. By understanding the IVF process and following your doctor’s instructions, you can enjoy the journey of your healthy pregnancy.

According to the data collected for 2014, these are the IVF success rates nationally, when using non-donor eggs, per egg retrieval. (These are not per cycle. In other words, these are the odds of a live birth after one egg retrieval, which may mean conception with fresh eggs/embryos in the cycle of the egg retrieval ​or after a frozen embryo transfer cycle in the following months.) 
Uterine exam. Your doctor will examine the inside lining of the uterus before you start IVF. This might involve a sonohysterography — in which fluid is injected through the cervix into your uterus — and an ultrasound to create images of your uterine cavity. Or it might include a hysteroscopy — in which a thin, flexible, lighted telescope (hysteroscope) is inserted through your vagina and cervix into your uterus.
PCOS: Polycystic ovarian syndrome (PCOS) is an ovarian issue that can cause irregular menstrual cycles and make it difficult for women to ovulate — a crucial part of the conception and pregnancy process. Women with PCOS do not release eggs regularly, and their ovaries often have many small cysts within. IVF is a strong option for women with PCOS, since it can help their bodies ovulate to achieve pregnancy.
Very slight elements of risk are associated with any medical intervention but for IVF the most notable risk in the past has been multiple births. The impact of multiple births on birth weight, premature delivery, and post-natal complications is well known. This is largely due to the practice over the past 30 years of transferring two or more embryos during IVF. Thanks to PGT-A testing and Single Embryo Transfer (SET), however, doctors can now feel confident about transferring just one normal embryo. At RMA, we have established SET as the standard of care going forward. With SET, the risk of multiple births is drastically reduced.
