Some observations on The New York Times article today: Firstly, IVF is so expensive that even mature adults with established careers need their parents to pay for it. Secondly, most eggs retrieved and frozen are not viable, that is, they will not become healthy embryos that result in live births. A typical result of a cycle with an egg donor in her 20s would be something like 12 retrieved, 10 mature, 7 fertilized, 2 transferred, 2 frozen, and with luck, a positive pregnancy that goes to term. If you retrieve 12 eggs and freeze them, not all will survive the thaw and fertilize. If a woman wants to preserve her fertility, she should do it in her 20s, but the need does not present itself until a woman is in her 30s.
