Guidelines for age limits for egg donors are set forth by the American Society for Reproductive Medicine (ASRM) and the Food and Drug Administration (FDA) for the health and safety of the egg donor. Additionally, minimum age requirements are set to protect the reproductive health of the donor and to make sure she has developed the maturity to understand the commitment of choosing to participate in an egg donation cycle. The maximum age is set to ensure the quality of the donor oocytes (eggs) is still optimal. As women reach their mid to late 30s, egg quality as well as egg quantity diminish.
