What is a vasectomy ? 

A vasectomy is a surgical procedure that prevents sperm from being present in a man’s ejaculate, resulting in male sterility. The procedure involves cutting both vas deferens, the tubes that carry sperm from the testicles to the prostate, the gland where semen is formed.

A vasectomy is considered a permanent method of contraception. There is a surgical procedure called a vasovasostomy that can reverse a vasectomy, but it is more complex and success is not guaranteed. It is therefore important to be certain that you do not want any more children before proceeding.

After a vasectomy, it usually takes three months and a negative semen analysis to confirm sterility, because sperm can remain in the tubes and prostate for several months. There is also a small risk that the tubes could reconnect, either within the first three months after the procedure or, more rarely, after three months. This is very rare, occurring in only about 0.2% of cases.
