The success rate of IVF depends on various factors such as the age of the woman, the reason for infertility, whether eggs are frozen or fresh, whether eggs are donated or are your own, and where the procedure is done. Here are some success rates based on age:
-
Under 35: The Society for Reproductive Technology (SART) states that for women under 35, the percentage of live births via IVF is 55.6% . The national average for women younger than 35 able to become pregnant by IVF on the first try is 55% .
-
35 to 37: IVF success rates for women aged 35 to 37 when using their own eggs is 40.8%. Live births based on the first embryo transfer is 31.6%. For a second or subsequent embryo transfer, the percentage of live births increases to 44.7% .
-
38 to 40: For women aged 38 to 40, the success rate is 26.8%, which is a considerable decline from 35 to 37 years of age. For 22.3% of women in this category, the first embryo transfer results in a live birth. For 40.9% of women in this category, the second or later embryo transfers result in a live birth.
Its important to note that the success rate for any given cycle remains constant, although cumulative pregnancy rates increase through a total of six attempts.
