Treatment Choice - Treatment Choice | Compare Prices | Find Hospital | A woman can get pregnant if a man’s sperm reaches one of her eggs (ova). Contraception tries to stop this happening by keeping the egg and sperm apart or by stopping egg production. One method of contraception is female sterilisation.<br/>Female sterilisation is usually carried out under general anaesthetic, but can be carried out under local anaesthetic, depending on the method used. The surgery involves blocking or sealing the fallopian tubes, which link the ovaries to the womb (uterus). <br/>This prevents the woman’s eggs from reaching sperm and becoming fertilised. Eggs will still be released from the ovaries as normal, but they will be absorbed naturally into the woman's body.
