That’s not really an option comparable to taking the pill. Firstly, it isn’t meant to sterilize, it works by effectively removing a person’s ability to become aroused. It also comes with a ton of side effects like reduced testosterone, osteoporosis, suicidal thoughts, etc.
At least with a condom, a guy can still have sex.
Granted, but generally women are still able to have sex on the pill. Chemical castration removes that ability entirely, on top of the side effects.
Presenting that in a thread discussing men undergoing voluntary surgery to sterilize themselves while stating that men make women handle birth control is a bit of a hot take there.
