> Increased life expectancy for women so far hasn't been matched by an increase in fertility beyond 40 years old.

You've said this with some certainty, were are you getting this from? This doesn't fit with all current data about general health and longevity, so I'd like to see who's saying this and what their case is.

The ovarian reserve doesn't somehow increase with increased longevity. The chart from Wikipedia is as good as anything on this: https://en.wikipedia.org/wiki/Ovarian_reserve#/media/File:Wa...

The ovarian reserve only decreases from birth, so it becomes less and less likely for a woman to conceive as they get older.

https://en.wikipedia.org/wiki/Age_and_female_fertility also notes: A review in 2012 came to the result that therapeutic interventions to halt or reverse the process of reproductive ageing in women is limited, despite recent reports of the potential existence of stem cells which may be used to restore the ovarian reserve

https://en.wikipedia.org/wiki/Advanced_maternal_age has some further good reading on this.
