I remember hearing a while back that somewhere in Europe a company had come up with a male birth control pill that overloaded your sperm with cholesterol and made them too fat to swim.
Not joking. As a guy, i’d personally love a birth control pill like this. Anyone know what became of it?

Doesn’t make them “too fat to swim” , but does deform them. Seems like the other version is merely hormones that can drop the sperm count of men to very low or even zero in some cases. In either case, we are looking at about 3 - 5 years.
