At age 40 and above women have reduced fertility potential as compared to that seen in younger women. When couples are trying on their own to get pregnant the fertility issue that reduces chances for success is related to the quality of the eggs. Most US IVF clinics have an upper age limit for allowing IVF treatment using "own eggs"of somewhere between 42 and 45 years of age. The quality of the egg is the most critical factor involved in determining the quality of the embryo. The quantity of eggs remaining in a woman's ovaries is often referred to as "ovarian reserve".
The quantity of remaining eggs probably does not have a large impact on natural fertility (trying to get pregnant "naturally"). The charts below illustrate the rate of live births per embryo transfer procedure by the age of the recipient of the embryos. Although these age and fertility statistics are specifically about IVF success, there is a similar loss in fertility potential with aging in the general "normal fertile" population.
The graphs below are from the 2012 ART Success Rates report published by the CDC, Centers for Disease Control and Prevention, a US government agency. Another point shown here is that there not a substantial decline in success by age of the recipient woman with donor egg IVF. The national summary (as well as clinic specific results) of IVF success rates for cycles done in years 1995 through 2012 are posted on the CDC website.
All clinics have some upper age limit after which they will not perform in vitro fertilization with the woman's own eggs. IVF can be used as an effective treatment for infertility of all causes except for women with infertility caused by an anatomic problem with the uterus, such as severe intrauterine adhesions. In vitro fertilization increases the efficiency of human reproduction, which is often not very efficient naturally.
With IVF we remove multiple eggs - and after careful culture for 3-5 days of the eggs that fertilize, we transfer one or more of the "prettiest" embryos back to the uterus.
We culture the embryos for several days and then pick the best one (or more) for transfer to the woman - selection of the best one(s) increases success. For example, if we transfer 2 embryos to the uterus and the female becomes pregnant - if there is one fetal heartbeat seen on early ultrasound (single pregnancy) the implantation rate is 50% (1 of 2 implanted).
Implantation rates are considered by fertility doctors when talking with couples about their chances for IVF success rates and multiple births. Implantation rates are used by in vitro fertilization labs to measure internal quality control. A weakness somewhere in the system (in the lab, or elsewhere) will cause implantation rates to drop as embryos become "weaker" - with a decreased ability to implant.
Our implantation rates for 2003-2005 were 47% for women under 35 years old, 33% for age 35-39, and 18% for women 40-42. Before you choose an in vitro fertilization clinic for your treatment, make sure you know the IVF success rates of the clinics you are considering.


Both SART and the CDC (US government agency) make this easy by posting success rates for all reputable IVF clinics on their websites.
As women age, the reproductive quality of their eggs begins to decline, making it increasingly difficult for them to get pregnant naturally without IVF or IVF using donor eggs. In this article I review the the United States Center for Disease Control statistics and pregnancy success rates for women 45 years and older using IVF with their own eggs. How do percentages of IVF cycles that result in pregnancies, live births, and singleton live births differ for women who are 40 or older? For women 44 and older, 3.3 percent of IVF cycles using their own eggs resulted in a live birth. A woman’s age is the most important factor affecting the chances of a live birth when her own eggs are used.
A woman’s age not only affects the chance for pregnancy when her own eggs are used, but also affects her risk for miscarriage. The percentage of IVF cycles that resulted in miscarriages began to increase among women in their mid?to late 30s and continued to increase with age, reaching 30 percent at age 40 and almost 58 percent among women older than 44.
How does a woman’s age affect her chances of progressing through the various stages of IVF?
As women get older, cycles that have progressed to egg retrieval are slightly less likely to reach transfer. The percentage of cycles that progress from transfer to pregnancy also decreases as women get older.
Overall, 1 percent of cycles started in 2008 among women older than 44 resulted in live births.
When attempting in vitro fertilization, the level of response of the ovaries varies greatly when women take the injectable FSH drugs for ovarian stimulation .
Before we stimulate the woman with the FSH containing drugs, antral follicle counts are the best predictor of the response the ovaries will give, and the number of eggs that will be retrieved. To a great extent, the more eggs we have to work with, the greater the chance that IVF will be successful. Women that respond well to the stimulation drugs sometimes also have better egg quality - and therefore could be more likely to have some high quality embryos. Women under 38 in our IVF program have acceptable live birth rates even with only 3 - 6 eggs, do better with more than 6 eggs, and do best with more than 10 eggs.
They also have substantially lower success rates with fertility treatments including in vitro fertilization (IVF). However, perhaps because we have five fingers on our hands we tend to think in fives and tens.
With treatments such as IVF, the issue that holds back success potential is both egg quality and egg quantity.
With IVF treatment we hope to get multiple embryos so we can choose the best ones from a group for transfer back to the uterus. The rate of chromosomal abnormalities in eggs (and therefore also in embryos) increases significantly with advancing female age.


However, when going through a fertility treatment such as IVF, the quantity of eggs remaining influences response to ovarian stimulating medications.
This report was generated from national data from hundreds of clinics and well over 100,000 IVF cycles. Women that have had tubal ligation and are considering tubal reversal surgery as well as men that are considering vasectomy reversal surgery might also consider IVF. In vitro fertilization and advanced maternal age is discussed in detail on the female age page. A day 3 FSH and estradiol test, antral follicle counts and AMH hormone levels are often done as screening tests for egg quantity.
Unexplained infertility means standard fertility tests have not found the cause of the fertility issue. More importantly, we see lower rates of implantation per embryo transferred (compare "Embryos Transferred" to "Fetal Heartbeats").
For those couples that had a day 3 embryo transfer procedure we estimated the number of day 5 blastocysts that (probably) would have been available if we had cultured all embryos until day 5. The implantation rate is usually defined as the percentage of embryos transferred that implant and develop to the stage of ultrasound documented fetal heartbeat. If there are two fetal heartbeats seen on early ultrasound (twin pregnancy) the implantation rate is 100% (both embryos implanted). If the rates drop significantly it should trigger a thorough evaluation of the entire IVF system. In general, while women in their 20s and 30s have many good quality eggs and few problems conceiving, women in their 40s and older may want to consult a doctor who specializes in fertility problems.
That’s because live births include women who have multiples like twins, triplets, and quadruplets.
As women age, we need more eggs to be able to make IVF work - because of the lower quality of the eggs.
So when the expected drop-off occurs as some embryos arrest their development (a normal process) - we will still have one or 2 "good" ones for transfer back to the uterus. Preimplantation genetic screening (PGS) can be used to test embryos for chromosomally normalcy (euploidy) prior to transferring them to the uterus.
Reduced egg quantity and quality is usually treated with either IVF, or with IVF with egg donation. The rate of miscarriage increases with the age of the female partner (compare "Fetal Heartbeats" to "Babies Born"). The purple arrows on the chart above show that some embryos will possibly be frozen after the embryos for transfer are selected. Embryos that have normal chromosomal analysis after PGS have a very high potential for implantation and live birth.
