Realistically, you can always undergo IVF unless you have experienced ovarian failure and/or menopause. However, pregnancy success rates using your own eggs drops considerably for women over 40.
Most fertility clinics set an age limit, often between 42 and 45 years old, for a woman to use her own eggs. However, the ASRM committee opinion concludes that "limited treatment may be provided after a process of explicit education and examination of values."
IVF and IUI Treatment through our Bulk Billed Program is therefore only available to women who are 45 years of age or younger (at the time of egg collection). However, if you are over 45, you may be suitable for IVF treatment through our Full-Service Fertility Program (you can see costs here).
IVF can however help improve chances of successfully conceiving a healthy baby, even after 40 years. the procedures of egg retrieval and screening of embryos can help improve pregnancy outcomes.
After 42, however, pregnancies are rare so in general we do not recommend them. At that point you should go to donor eggs. If you don't want to keep trying with your own eggs, or you've reached the end based on answers to the above two questions, then your best bet is donor eggs.
Pregnancy in Your 40s
If you get pregnant after 35 years old, experts call this an “advanced maternal age” pregnancy. But it's still possible to get pregnant and deliver a healthy baby in your 40s. Childbirth at older ages has become more common too. Since the 1990s, birth rates in people aged 40-44 have gone up.
The success rate using eggs over age 44 is about 1% per attempt.
IVF Success Rates Over 40
For women over 40, the IVF success rate is around 7%, with women under 42 having a higher rate of success than women over 42 years of age. In many cases, women over 40 may decide to use donor eggs.
For women ages 35-37, the IVF success rate is 38.3% for live births using the patient's own eggs for a singleton (one child) birth. At ages 38-40, the percentage drops to 25.1%, and for 41-42, it is 12.7%.
So on average, when we look at large groups of women, of women who want to conceive at age 40, about half will get pregnant naturally. But that decreases quickly to perhaps 20% to 25% by age 42 to 43. And by age 45, it's quite rare to become pregnant naturally. Dr.

Studies show that women in their 20s and 30s have the most success when getting pregnant through IVF and other reproductive technologies. According to the CDC, the average percentages of assisted reproductive technology (ART) cycles that lead to a live birth are: 31% in women younger than 35 years of age.
The short answer is there isn't a standard maximum IVF age limit. Although rare, women over 50 have had successful pregnancies with IVF. However, it is more common practice to limit the upper age for IVF patients to around the mid-40s.
Pregnancy after age 45 years is infrequent and the mother and baby should be considered as a high risk. There is a greater incidence of spontaneous abortion, gestational trophoblastic disease and chromosomal abnormalities in the fetus.
At an average, your chances of getting pregnant at 40 with Natural IVF* is 9%, whilst your chances with Mild IVF* are 20%. However, it is important to note that your chance of IVF success is dependent on your own specific circumstances.
IVF Success Rates by Age
For women ages 35 to 37, the percentage of live births per egg retrieval is 41.1%. For women ages 38 to 40, the percentage of live births per egg retrieval is 26.7%. For women ages 41 to 42, the percentage of live births per egg retrieval is 13.8%.
Thus, the pregnancy rate even with IVF (using her own eggs) is less than 5% in women above age 42 years. They are even lower at age 44 and practically zero at age 45 years.
Can you have a normal, healthy pregnancy at 45? Yes. Assuming you have top-notch prenatal care during your pregnancy, you eat well and have a healthy lifestyle, you take care of yourself during your nine months, and you come into your pregnancy as healthy as can be, your pregnancy can be problem-free.
Women have “perfect” eggs below the age 30, but then egg quality starts to decline, which explains declining fertility. Over the age of 45, almost all the eggs which fertilise will create chromosomally abnormal embryos and therefore the chance of healthy, ongoing pregnancy is close to zero.
For women aged 40-41 when they started, there was a 13 per cent chance of a baby after one cycle, a 21 per cent chance after two cycles and a 25 per cent chance after three cycles.
“The live birth rate per cycle start was 14% at the age of 40, declining to 1%-2% at the age of 44-45, and 0% over the age of 45.” With multiple IVf cycles this same group had a cumulative IVf success rate (after an average of 2.3 IVF cycles) of 28% at age 40 and 0% over age 45.
Women under the age of 35 are the most likely to benefit from a six-cycle regimen. Women 40-42 (using their own eggs) had a 31.5% live birth rate at the six-cycle mark. Women older than 42 (using their own eggs) had a <4% live birth rate at the six-cycle mark.
By 40, less than half of a woman's eggs are considered normal. Egg quality is largely determined by the ovarian environment that the eggs spend their final 90 days of development in; women in their 40s generally have a poor ovarian environment for producing high-quality eggs.
It is true that fertility does decline with age, but many women conceive naturally aged over 40 and go on to have healthy pregnancies and healthy babies.
By the time a woman reaches 40, she'll be down to about 18,000 (3% of her pre-birth egg supply). Although the chances of conception are lower, this does not mean it is impossible to conceive at this age.
