Oocyte donation

Oocyte donation is widely practiced worldwide, and since its introduction, almost 30 years ago, has become an extremely efficient therapeutic approach for both pre- and postmenopausal women who are in need of donor eggs. Like any other field in medicine, and in particular, reproductive medicine, many of the current practices associated with donor and recipient preparation and treatment have not been standardized. The purpose of the current survey is to explore current trends, practices and various issues related to donor and recipient evaluation and treatment.
The survey is conducted by Dr. Ariel Weissman, Wlfson Institute, IVF Center, Israel
