Female sterilization is called tubal ligation or ‘tying the tubes.’
Female sterilisation is a heavier operation than a vasectomy. Normally it’s performed under general anaesthesia, although sometimes a local anaesthetic is used.
The fallopian tubes may be (1) cut, sealed and bound together, (2) tied off, (3) blocked, burning the tissue or (4) clamped. The fourth method is more easily reversible than the other methods and therefore used most often.
The operation makes it impossible for sperm to unite with an egg cell and for egg cells to get to the uterus, thus preventing pregnancy.
