I won't say for sure that his points are correct, but evolution programmed women (and men) to get horny and want to have sexual intercourse. Then during pregnancy oxytocin helps develop a bond with the child to take care it. There's surely a lot of other little hormonal imperatives but that's the main thing. His assertions about women without children doesn't conflict with biology. The only one I can see someone taking issue with is "avoid accountability" but that can be a compound result of other unstated imperatives.
