Egg donation is already a vital therapy for some infertile couples. The ASRM and SART have in place strong guidelines on how to screen, counsel, and compensate potential egg donors. All these guidelines could be used if seeking donors for stem cell or SCNT purposes as well as for reproduction. The ASRM is already working with the FDA to develop regulations on donated reproductive tissues. These would apply whether these tissues are to be used for reproductive purposes or for stem cells.
