Does freezing eggs affect fertility?

Freezing eggs does not negatively impact their viability or the chances of successful pregnancy later on. The survival rate for thawed eggs is about 90%, and technology has dramatically improved over the past decade, making the process more efficient and reliable. Dr. Natalie Crawford highlights that the quality of eggs and the number of eggs decline with age, particularly after 35. Therefore, starting the process earlier, especially in one's late 20s or early 30s, can be beneficial. This allows for multiple rounds of egg collection and freezing if necessary, without diminishing the number of eggs available 1.

Dr. Andrew Huberman supports this idea, emphasizing that the process of harvesting eggs for freezing does not affect future fertility. It simply utilizes the eggs that are naturally released from the ovarian reserve that month, without affecting the total number of eggs 2.
