Younger is better, experts agree. ''If you do egg [harvesting and freezing] on someone in her 20s, you could probably get a good number of eggs, 15 to 25," Doctor says. "Four or five eggs at one time would be enough to produce one pregnancy, one baby."
"If you look at someone 40, from that person you may only collect 8 to 10 eggs. And perhaps she would need 25 eggs to have one baby." Some eggs don't survive the thawing process, and some eggs that are retrieved won't fertilize, among other problems.
If women can freeze their eggs before age 35, expert says, ''that will make a big difference,'' with better outcomes.
The healthiness of an egg is the primary factor that should be considered if one is planning to freeze their eggs. The prime reproductive age range for women is between 16 and 28, although one can usually count on good quality eggs until the age of 38. From 39-44, women may retain viable eggs but have a lower probability for a successful pregnancy. While oocytes should be saved when they are as healthy as possible these decisions should be made on an individual basis, depending on a patient’s life circumstances. While at EFC we recommend that women freeze their eggs in their 30s and 40s, there is no age limit for the procedure and if you are 42 or 44, although your chances are lower, we will not turn you away simply to boost our success rates. On an individual, case-by-case basis we are happy to help patients talk about options and find solutions that match their personal circumstances.

We also recommend that anyone who is considering fertility preservation have an antral follicle count and hormonal blood tests with their annual pap smear. These tests will provide an important assessment of your fertility status and will allow you to make informed decisions about when to start a family or freeze your eggs. An antral follicle count is a sonogram that shows how many follicles (eggs) you have in reserve. This will tell us how much time you have left on your fertility clock.
