Is there a shot or pill a guy would get from a doctor every two months to make him sterile for a certain amount of time?

There isn't any shot/pill for a guy at this time to prevent pregnancy. The only forms of Birth Control are condoms and vasectomies. There is a very interesting article on this very subject.

No, there is no shot or pill for a man to become sterile. In about 5-10 years they may release on they are working on, but not at this time. You need to leave this guy. That is an enormous lie! And breast tenderness can be a sign of pregnancy. You should go to a doctor and have a test done. This is very serious. For him to do that is very, very bad.

I knew a guy who just dipped his balls into really hot water for a minute or so, every day. The theory is it kept the sperm from being viable.
