Sterilisation is a permanent method of contraception, for people who don’t want more children, or any children.
It works by stopping sperm from meeting an egg.
Male sterilisation (vasectomy) is done by cutting and sealing or tying the vas deferens (the tube that carries sperm from the testicles to the penis).
Female sterilisation (tubal occlusion) is done by cutting, sealing or blocking the fallopian tubes which carry an egg from the ovary to the uterus (womb).
