Unlike the Catholic perspective, halacha does not view an embryo as a human life. Thus, according to halacha, it is permissible to dispose of excess embryos outside the womb.
Should Jews donate embryos, one halachic concern would be with keeping track of all of a couple’s progeny to avoid any future chances of incest. However, in certain cases, it might be permitted for a Jewish couple to donate an embryo, under rabbinic guidance. Technically, donation is not considered adoption.
If you’d like to discuss this further, we invite you to arrange a personal consultation with a Nishmat Fertility Counselor, a Yoetzet Halacha who has completed additional specialized training in this area. Consultations are free and can take place in person, by phone, or via internet conference.
