I know it's not the most important thing right now, but since the Roe v Wade news there have been a bunch of tweets encouraging men to get vasectomies, and/or trying to analogize between female birth control methods and vasectomies, that include some assertion to the effect of "you can just get it reversed later when you're ready for kids".
This is not true. Yes, the vasectomy reversal procedure exists but its success rate is not very good (70% at best), and the likelihood of restoring fertility only goes down as more time passes since the initial vasectomy. This is why urologists advise their patients to consider a vasectomy to be a permanent procedure.
I won't say much more about it, other than it would be nice if more forms of male birth control (e.g. Vasalgel) entered the market soon.
My take is that Anti-Natalism fundamentally misunderstands the point of reproduction/having kids. Like, it's not supposed to be a weird utilitarianist calculus to figure out whether or not the kid you'd end up having is gonna end up experiencing more Utils of pleasure (or whatever the fuck we're gonna use as a calculation). It's about the continuation of the species, and of human social bonds.
