Have you considered that women are just not interested in chess, or are generally worse at it than men, so they rage-quit?
Hou Yifan, "The Queen of Chess" is ranked #1 among women has a FIDE rating of 2651, which places her below 100th place among men.

That distribution is actually normal, considering how many more men play chess than women. But I haven't heard a good explanation on why so few women play chess in the first place (other than the two reasons I suggested).
