Vasectomy is a surgical intervetion to seterilase men. Once it has been performed no more sperm is expelled and pregnancy cannot take place.
Vasectomy reversal, or vasovasostomy, is a simple surgical intervention of two hours, after which the man recovers his reproductive capacity.
Vasectomy must be only chosen as a contraceptive method when a man is convinced that he does not want to have more children. Although it is a sterilisation procedure, there are options for being father again, if desired.
