IVF Success Rates by Age
Age is one of the most important factors affecting in vitro fertilization (IVF) success rates. Below, we share IVF success rates, by age group, as reported to the Society for Assisted Reproductive Technologies (SART) in 2012.
These rates show the percent of women giving birth after an embryo transfer with IVF. First, we share IVF success rates for women that used fresh embryos. The second group of success rates below shows birth rates for women that used frozen embryos with IVF.
IVF success rates with fresh embryos - 2012
- Women under 35: 47.1 %
- Women 35-37: 37.9 %
- Women 38-40: 28.5 %
- Women 41-42: 16.3 %
- Women 42: 6.1 %
IVF success rates with frozen embryos - 2012
- Women under 35: 42.4 %
- Women 35-37: 39.8 %
- Women 38-40: 33.9 %
- Women 41-42: 26.4 %
- Women 42: 17.8 %
As women age, they have lower IVF success rates.
IVF success rates tend to be higher for younger women for two main reasons.
- The quality/genetic makeup of a younger woman's eggs is often better.
- Younger women usually produce more eggs for retrieval with IVF. Having more eggs may lead to more embryos, allowing a doctor to choose the best embryo from the group for transfer.
It is important to remember that these rates above are averages and each couple’s chance of success depends on several factors including age, diagnosis and prior treatment history.
Donor egg IVF success rates
If you are having trouble getting pregnant with IVF, ask your doctor about IVF with donor eggs. Donor egg IVF may increase your chances of conceiving.
Donor eggs are often considered for women over 38 or for younger women who have few eggs of their own. When donor eggs are used, IVF success rates increase significantly.
When it comes to conceiving with donor eggs, the age of the woman who donates her egg is often more critical than the age of the woman carrying the pregnancy.
- In 2012, 56.6 % of fresh donor egg embryo transfers resulted in live birth.
- 37.2 % of frozen and thawed donor egg embryo transfers resulted in live birth in 2012.
Ask your doctor about IVF success rates
To get the best idea of your personal chances of success with IVF, talk with your doctor. Openly discuss your medical history, including test results and fertility history. Then ask about the benefits and risks of IVF to you.
An open and honest discussion will help you make the best decision about whether IVF may help you have the baby you are dreaming of.Sources
