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]

This chart is US national average data on success rates per IVF cycle by female age for 2014. The dark blue line (triangles) shows pregnancy rates per cycle by age. The orange line (circles) shows live birth rates per cycle by age. The rate of singleton live births per cycle is shown by the light blue line. The difference between "pregnancy" rate and "live birth" rate is due to miscarriages.
Treatment depends on the cause of infertility, but may include counselling, fertility treatments, which include in vitro fertilization. According to ESHRE recommendations, couples with an estimated live birth rate of 40% or higher per year are encouraged to continue aiming for a spontaneous pregnancy.[63] Treatment methods for infertility may be grouped as medical or complementary and alternative treatments. Some methods may be used in concert with other methods. Drugs used for both women and men[64] include clomiphene citrate, human menopausal gonadotropin (hMG), follicle-stimulating hormone (FSH), human chorionic gonadotropin (hCG), gonadotropin-releasing hormone (GnRH) analogues, aromatase inhibitors, and metformin.
West states that the "hardest thing about secondary fertility issues is that you want a sibling for your child." Fiona, who has a son of five and has been trying to conceive a second child for two years, says she can no longer look out of the window at her son playing in the garden. "It breaks my heart. He just looks so alone out there. All I want is a sibling for him but I don't think it's going to happen."

PMID 7988065. There is now substantial evidence that coeliac sprue is associated with infertility both in men and women. (...) In men it can cause hypogonadism, immature secondary sex characteristics and reduce semen quality. (...) Hyperprolactinaemia is seen in 25% of coeliac patients, which causes impotence and loss of libido. Gluten withdrawal and correction of deficient dietary elements can lead to a return of fertility both in men and women.
The cost of an IUI is almost certainly less on a per cycle basis, but because IVF has much higher success rates and IUI is a poor option for some, the higher per cycle cost of IVF can actually be more affordable in the long run – in terms of the cost to bring home a baby.  Because most successful IUIs happen in the first three or four-cycle, it eventually becomes very expensive to bring home a baby with an IUI.

For women, problems with fertilisation arise mainly from either structural problems in the Fallopian tube or uterus or problems releasing eggs. Infertility may be caused by blockage of the Fallopian tube due to malformations, infections such as chlamydia or scar tissue. For example, endometriosis can cause infertility with the growth of endometrial tissue in the Fallopian tubes or around the ovaries. Endometriosis is usually more common in women in their mid-twenties and older, especially when postponed childbirth has taken place.[55]


A lot goes into determining your odds of IVF success. No matter how small or big each factor is, you should try to optimize all of them for a happy outcome. Don’t forget, you can also use the success rate calculator for a personalized predication. It is also important to plan multiple full IVF cycles no matter what the first IVF cycle outcome is. 3 full IVF cycles are generally recommended to improve your cumulative success rates. About two thirds of patients will be successful after six or more cycles of IVF.

Addressing lifestyle issues is not meant to be a quick fix, and typically does not lead to instant success. However, with unexplained infertility every little bit counts, so don’t fret or give up. Do not assume just because the cause of infertility is unexplained, it is untreatable or there is no pathway to parenthood. When a specific cause is not determined for women, and male infertility has also been ruled out, our fertility specialist may begin a course of treatment to improve the chances of conception and pregnancy. The speed with which interventions are offered depends on each individual’s own needs and desires as determined by age and other factors.
As with any medical procedure, there are some risks to keep in mind. When choosing between IUI and IVF, the risk is certainly something to consider. The chances of experiencing either a miscarriage or multiples are concerns many have when deciding to undergo fertility treatments. So let’s take a look at the odds of either of these things occurring, plus a few other risks to be aware of.
Gene mutations in men and obscure viruses in women can cause infertility. Here’s a basic list of the most commonly known reasons men and women can’t get pregnant, plus four research studies that describe lesser known causes of male and female fertility problems. If you’ve been trying to get pregnant for more than a year,… Read More »Causes of Infertility for Men and Women Who Can’t Get Pregnant
Other health related problems could also cause poor egg health, low ovarian reserve, or abnormal immunological responses, which can affect conception. Stress could also play a role. We all know that menstrual cycles can be altered during times of extreme duress- and this can be emotional, physical, or environmental stressors. In these instances, the first steps should be to avoid life stressors, maintain a healthy weight, routinely exercise, avoid smoking, and reduce alcohol intake, all of which may be contributing to unexplained infertility issues.
The stress of secondary infertility on an individual's life and relationships can be significant. It can be hard to find support from family and friends, especially when a woman or couple already has/have children. Sentiments such as, "you should be grateful for what you have," or, "just keep trying," almost never serve as useful advice or support. Couples and single parents can even experience resentment from other couples with infertility who are unable to even have their first child.

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.
Risk of ectopic pregnancy. Women who have difficulty getting pregnant have an increased risk for ectopic pregnancy, regardless of how they conceive. And all assisted reproductive technology treatments, including IVF, also make an ectopic pregnancy more likely. An ectopic pregnancy occurs when an embryo implants in a fallopian tube or the abdominal cavity rather than in the uterus. It's treated with the medication methotrexate or by surgically removing the embryo to prevent it from severely injuring the mother by continuing to grow.
Ovarian stem cells: it is thought that women have a finite number of follicles from the very beginning. Nevertheless, scientists have found these stem cells, which may generate new oocytes in postnatal conditions.[67] Apparently there are only 0.014% of them (this could be an explanation of why they were not discovered until now).[citation needed] There is still some controversy about their existence, but if the discoveries are true, this could be a new treatment for infertility.

The live birth rate is the percentage of all IVF cycles that lead to a live birth. This rate does not include miscarriage or stillbirth; multiple-order births, such as twins and triplets, are counted as one pregnancy. A 2017 summary compiled by the Society for Assisted Reproductive Technology (SART) which reports the average IVF success rates in the United States per age group using non-donor eggs compiled the following data:[10]
One in 8 couples (or 12% of married women) have trouble getting pregnant or sustaining a pregnancy. Infertility is defined as the inability to get pregnant after regular sexual intercourse without the use of any contraceptive methods for 6 months for those 35 years old or over, or 12 months for those under 35.(1)  Under normal circumstances the ability to get pregnant is at the most 25% each month. This number declines over time and starts to decline more rapidly once a women reaches her thirties, so that by age 35, the likelihood of getting pregnant each month is down to about 15%, and by age 40 it’s down to less than 10%.
With egg donation and IVF, women who are past their reproductive years, have infertile male partners, have idiopathic female-fertility issues, or have reached menopause can still become pregnant. After the IVF treatment, some couples get pregnant without any fertility treatments.[3] In 2018, it was estimated that eight million children had been born worldwide using IVF and other assisted reproduction techniques.[4] However, a recent study that explores 10 adjuncts with IVF (screening hysteroscopy, DHEA, testosterone, GH, aspirin, heparin, antioxidants in males and females, seminal plasma, and PRP) suggests that until more evidence is done to show that these adjuncts are safe and effective, they should be avoided.[5]
I had a wonderful experience at CHA Fertility Clinic and got pregnant on my first cycle.  My son will turn two this year and I immediately contacted them when we were thinking of having a second child.  The doctors and staff are so kind, informative, and helpful, and they really put my mind at ease.  We had looked at other fertility clinics … Read More
