Yes! The age of the female partner is the single most important factor in achieving a viable pregnancy. This is because age directly affects the following:
The quality and the number of eggs. There is also an increased risk of miscarriages and abnormalities with advanced maternal age.
The ability to have a healthy baby decreases gradually but significantly from 32 years of age to almost Nil at the age of 46.
High FSH >10 on day three is the second most important factor, even in younger patients. If found, it severely reduces the chances of pregnancy with any treatment, including IVF.
