Is there a birth control method for guys to use?

Condoms and vasectomies are the only reliable types of birth control for men. Any other types of Birth Control are for women. The withdrawal method is another type for men but is known to be one of the most unreliable when used over many encounters. There is a lot of research money going into a male contraceptive, and one will most likely be found in the next five years. Previous attempts have resulted in drugs that had side effects that reduced a man's desire and were not well received. One promising new method involves stopping the sperm from developing the tail that helps them swim. Also, there is a type of vasectomy that is designed to be reverseable.
