<unk> (also spelled<unk>  is any of a number of medical methods of birth control that intentionally leaves a person unable to reproduce.<unk> methods include both surgical and non-surgical, and exist for both males and females.<unk> procedures are intended to be permanent; reversal is generally difficult or impossible. There are multiple ways of having<unk> done, but the two that are used most frequently are tubal ligation for women and vasectomy for men. There are many different ways tubal<unk> can be accomplished. It is extremely effective and in the United States surgical complications are low. With that being said, tubal<unk> is still a method that involves surgery, so there is still a danger. Women that chose a tubal<unk> may have a higher risk of serious side effects, more than a man has with a vasectomy. Pregnancies after a tubal<unk> can still occur, even many years after the procedure. It is not very likely, but if it does happen there is a high risk of ectopic gestation. Statistics confirm that a handful of tubal<unk> surgeries are performed shortly after a vaginal delivery mostly by minilaparotomy. In some cases,<unk> can be reversed but not all. It can vary by the type of<unk> performed.
