Principles of contraception
Keyword(s):
There are many contraceptive methods available (increasing year on year) which can be classified as: hormonal and non-hormonal, longer lasting, and those with a shorter duration of action, reversible and irreversible. No contraceptive method is 100% effective (apart from abstinence) and where there is potential risk of conception due to unprotected sex or an error with a contraceptive regimen, the patient must be informed about methods of emergency (post-coital) contraception, the most effective being the post-coital intrauterine device (PCIUD). Education of the public about the benefits of contraception is vital and must be done in a timely way (e.g. through school sex education, media, and online resources).
