ONLY is a strong word.
After all, MEN have had hysterical pregnancies. I'd love to have been in the ER when THAT came through.
Certainly Munchausen and Munchausen-by-proxy are almost exclusively by women. Men almost never kidnap so they can have children to take care of (raping is a different issue). There are bunch of different psychological issues that are mostly women, but not exclusively.
Women are more likely to be passive aggressive, claim ignorance, deny their own agency etc, than men, but men have and will continue to do these things occasionally.
