Vasectomy is a relatively permanent procedure — meaning if a man decides he wants to father a child after he’s had a vasectomy it can be very difficult and expensive with no guarantee of success.
It is possible to store semen in a sperm bank to preserve the possibility of producing a pregnancy at some future date. Doing this is also expensive and stored semen does not always stay healthy enough to make pregnancy possible. For all of these reasons, doctors advise that vasectomy be undertaken only by men who are prepared to accept the fact that they will no longer be able to father a child. The decision should be considered along with other contraceptive options. Men who are married or in a serious relationship should also discuss the issue with their partners.
