What qualifies someone as an experienced donor?
There is no universal definition for a proven donor, but it is commonly accepted amongst fertility doctors that a proven donor is somebody whose egg or eggs have been successful. Success is not measured by a positive pregnancy test but by a successful live birth. It does not mean a good embryo or a genetically normal embryo. Of course, the goal of any donor is to provide a genetically normal embryo, a proven donor is based solely on a successful live birth.
Are non-proven egg donors bad?
Everybody has to start somewhere, there are plenty of amazing egg donors whose eggs haven't gotten the chance yet to prove themselves. So, it is important not to dismiss a potential match because they haven't had the opportunity yet to show their full potential.
