A perfectly legitimate question. Eggs can be frozen for a long time and often are, until ultimately being disposed of. Id rather the children be born than thinking their death is OK as they otherwise might have had bad parents, homosexual parents, poor parents, 1 parent, etc. There is no situation bad enough to justify abortion which ultimately is no different than throwing away the embryos. It is important to distinguish between frozen eggs and frozen embryos.
I see absolutely no moral dimension to freezing, conserving, and/or disposing of frozen eggs.
