>Given that female humans are the only female mammals with this egg limitation I bet we can crack this with stem cells too We can, eventually, I'm sure. Biology is just a mechanism, and with enough work and knowledge, we can figure it out. However, would it make much difference? I'm thinking most women don't have children because they don't want them (or any more of them), not because they've become infertile due to age. In fact, most mothers seem to lost all interest in having more kids after having 1 or maybe 2: going through the experience shows them the grim reality of child-rearing, so once they've "done their part" with 1 or 2 kids, they've had enough. Perhaps, if we achieve biological immortality, along with eliminating age-related infertility, people will have more kids, because they could afford to wait a long time between them. They could have the first one at 30-50, after they've gotten themselves financially situated, then they could take a break for a few decades, then have another one, then take another break, etc. Maybe after 2-3 decades, they'll have forgotten what a pain in the ass the previous one was.
