Am I eligible if I only have one ovary?

You will need two functioning ovaries in order to be eligible. There are many factors to take into consideration when screening and accepting donors into our program. One of the most important things we look at is a donor’s expected ovarian reserve. We do this by evaluating blood work and something called an Antral Follicle Count. Antral follicles are small follicles (where the egg is stored) that we can see and measure with ultrasound to estimate the ovarian reserve. This helps us to determine how much stimulating medications will need to be used and the chance for a successful pregnancy using in vitro fertilization. The number of antral follicles are an indication of how many eggs we should expect to be able to stimulate and potentially develop into mature eggs to be able to retrieve and freeze.

When there are only a few antral follicles, there are fewer eggs to work with. The number of eggs retrieved correlates with IVF success rates. When we are starting with only one ovary, our possible yield of mature eggs for each cycle is cut in half. When there are an average or high number of antral follicles, we tend to get a good response, good number of eggs and higher pregnancy rates. When there are fewer antral follicles, as expected in someone with only one ovary, we tend to have a lower response, sometimes cancelled cycles and lower pregnancy rates. This has no bearing on your own ability to become pregnant and have your own children; this is purely in the context of becoming a donor and undergoing stimulation with an egg retrieval.
