Q. Re- question above of not performing a Bris Mila on Shabbos for a baby whose father isn’t Jewish. If a child is born by IVF from an egg donated by a Gentile mother, is the Bris done in Shabbat?

A. In Vitro Fertilization (IVF) using mature eggs collected (retrieved) from ovaries and fertilized by sperm in a lab, is not uncommon in our days. In the case above, likely the baby will require conversion, and the Bris therefore cannot be done on Shabbos.
