A non-hormonal, reversible and non-toxic male birth control could be a step closer, with scientists successfully targeting a protein that's crucial in making fertile sperm. Knocking this protein out for a period of time would give men control over their protection window, much like oral…
The Caveat is that it is permanent and irreversible for the average person with very few exceptions.
EDIT: added “for the average person”
That’s kinda the point
Also why it isn’t a replacement for birth control.
Another caveat is that it’s not allowed for men under 25 in my country (Sweden). “My body - my choice” only applies to one gender lol
edit: Although, to be fair, sterilisation is also not allowed for women under 25. They do ofc have many more options though
