An updated guide to contraception. Part 3: Permanent methods, traditional methods and emergency contraception

摘要

Permanent methods of contraception have high efficacy but their usage is falling, which may relate to increased awareness and uptake of long-acting reversible contraception. Traditional methods - the barrier methods, fertility awareness methods, withdrawal and lactational amenorrhoea - remain valued options despite lower efficacy in typical use than modern methods. Emergency contraception has an important role in reducing the number of unintended pregnancies.
