Combined pill

The combined oral contraceptive pill, usually just called "the pill", contains artificial versions of female hormones oestrogen and progesterone, which women produce naturally in their ovaries.

A woman can get pregnant if a man's sperm reaches one of her eggs (ova). Contraception tries to stop this happening usually by keeping the egg and sperm apart or by stopping the release of an egg (ovulation).

The pill is over 99% effective if used correctly. Some women find it difficult to take the pill at the same time every day, and it's less effective if not used correctly. Other methods of contraception are better at preventing pregnancy, such as the IUD, IUS, implant and injection.
