That part doesn't surprise me. Why would they think any differently? Men are completely unable to comprehend what it's like to have a period, let alone the stress to the body done by pregnancy &/or childbirth.

Think about all the things women go through for birth control and gynaecological related procedures, and then compare the reaction of most men* when you suggest they be responsible for birth control - Oh no, you're not cutting into my testes. Sickening.

*this includes the men who are willing to have a vasectomy.
