For this reason when men are initially considering a vasectomy they're advised to think of it as a permanent operation. If they have the slightest doubt as to whether they may wish to have children in the future then it's best for them to think about an alternative form of contraception. This can make it difficult to make a patent connection that allows sperm to easily pass through. Having a vasectomy reversed is not always available on the NHS, it is, however, available privately but be aware that it can be quite expensive. The operation is done as a day-case procedure either under local or general anaesthetic.
