Clearly it's easier to conceive in your 20's for both men and women, but menopause (which tends to happen around age 50) is not necessarily the end of the story

Clearly it's easier to conceive in your 20's for both men and women, but menopause (which tends to happen around age 50) is not necessarily the end of the story for women. Women can often become pregnant after menopause with their own pre-menopausal frozen eggs. If not, they can more often use a surrogate to bring their frozen egg to term. This can cost up to $40k for the procedures and storage, which is expensive but getting cheaper over time. I'd be surprised if girls being born now are ever nearly as anxious about menopause as today's quinquagenarians.
