A 2016 study of 1,171 IVF cycles using frozen eggs found that, for women under 30, each egg retrieved had a 8.67% chance of resulting in a child; for women over 40, that chance dropped to less than 3% per egg at best. More likely closer to 1%. Reminder: If you are a woman, plan on having children in your 20s. If you’ve frozen your eggs you’ve probably wasted your money.
