Sterilisation - Disadvantages

Women
Female sterilisation does not protect you against sexually transmitted infections so you should still use a condom if you are unsure about your partner's sexual health. The most difficult thing to do is to reverse a tubal occlusion - this involves removing the blocked part of the fallopian tube and rejoining the ends.

Men
You will need to use contraception after the operation until tests show your semen is free of sperm - if your semen contains sperm, you could make your partner pregnant. It's difficult to reverse vasectomy.
