Wikipedia
Egg donation is the process by which a woman donates eggs for purposes of assisted reproduction or biomedical research. For assisted reproduction purposes, egg donation typically involves in vitro fertilization technology, with the eggs being fertilized in the laboratory; more rarely, unfertilized eggs may be frozen and stored for later use. Egg donation is a third party reproduction as part of assisted reproductive technology (ART).
In the United States, the American Society for Reproductive Medicine (ASRM) has issued guidelines for these procedures, and the FDA has a number of guidelines as well. There are boards in countries outside of the US who have the same regulations. However, egg donation agencies in the U.S. can legally choose whether to abide by ASRM regulations or not.
