What it is?
A minor operation to seal, tie or cut the vas deferens (narrow tubes that carry sperm from the testicles to the urethra). This procedure can be performed under a local or general anaesthetic.
How it works
This procedure will prevent the sperm from mixing with semen during ejaculation. An egg is unable to be fertilised without sperm, therefore, preventing pregnancy.
Sperm is still produced but instead of being released, the body absorbs it.
