Sterilisation – Class 12 | Chapter – 4 | Biology Short Notes Series PDF

Sterilisation: Female sterilisation is an operation to permanently prevent pregnancy. The fallopian tubes are blocked or sealed to prevent the eggs reaching the sperm and becoming fertilised.

Facts about female sterilisation

  • Female sterilisation is more than 99% effective at preventing pregnancy.
  • You do not have to think about protecting yourself against pregnancy every time you have sex, so it does not interrupt your sex life.
  • It does not affect your hormone levels and you’ll still have periods.
  • You’ll need to use contraception up until you have the operation, and until your next period or for 3 months after the operation (depending on the type).
  • As with any surgery, there’s a small risk of complications, such as internal bleeding, infection or damage to other organs.
  • There’s a small risk that the operation will not work. Blocked tubes can rejoin immediately or years later.
  • If the operation fails, this may increase the risk of a fertilised egg implanting outside the womb (ectopic pregnancy).
  • It is very difficult to reverse, so you need to be sure it’s right for you.
  • It does not protect against sexually transmitted infections (STIs), so you may need to use condoms as well.

How female sterilisation is carried out

  • Applying clips – plastic or titanium clamps are closed over the fallopian tubes.
  • Applying rings – a small loop of the fallopian tube is pulled through a silicone ring, then clamped shut.
  • tying, cutting and removing a small piece of the fallopian tube.
