For couples in a stable relationship who have completed their family, a vasectomy takes away the concern of unplanned pregnancy.
Using the modern 'no-scalpel' technique, the vasectomy is performed with minimal discomfort. Make sure both you and your partner have no reservations about having a permanent form of contraception. Even though we can reverse the procedure it is not always successful so a vasectomy should be considered irreversible.
When planning for the operation, make sure you have allowed 2 days to recuperate afterwards (longer if you have a strenuous manual job) and that you need to arrange someone to take you home afterward.
Please do not hesitate to have a separate operative consultation if you have any doubts or concerns.
