What does a Jewish child need most from a mother? Forget about the chicken soup””it’s all about the eggs, say a growing number of prominent rabbis. Several recent rabbinic rulings on fertility treatment dictate that a child conceived in vitro is Jewish only if the egg came from a Jewish woman.
The issue is most pressing in Israel, in part because tight restrictions on egg donation have long compelled infertile women to procure eggs abroad, where most donors are not Jewish. But decisions in Israel favoring the genetic mother over the gestational one are also likely to increase the already high demand for Jewish eggs in the U.S., and could call into question the religious status of thousands of children born to Jewish women around the world.
