Right but even in man's prime he has very few dating choices compared to much older women.

An average man in his prime on a dating app gets 20 matches for every 100 swipes.

A woman, even a below average woman can get 80 out of 100.

Additionally, nowadays you will find on dating apps even women past 40 still have abundant matches. This is a modern phenomenon though. In the past what you said is largely true but with dating apps the game has leaned heavily in favor of women on all fronts.

What's happening is the age group is just shifting. If the woman is in her 20s her age group is 20 to 30, if she's in her 40s it shifts to 40 to 60. As the pool for younger men closes an older pool opens up. Dating apps is what enables this as women can now find matches outside of local networks.

Actual fertility is a different story though.
