Currently, a non-profit foundation is developing a male birth control to eliminate the need for monthly female birth control and contraceptives. It's called Vasalgel, and it's essentially a gel injection into the vans deferens that then ruptures the membranes of sperm, thus preventing them from progressing. It's a one-time injection, and can supposedly be reversed at any time. It's currently within the animal testing phase, and is set to start the human testing phase next year.
