Contraception is any method used to prevent pregnancy by stopping fertilisation or implantation of an egg. Methods can be hormonal, barrier, or other approaches.

How does the contraceptive pill work?

The pill contains synthetic oestrogen and/or progesterone. These keep hormone levels high, which inhibits FSH release from the pituitary — preventing egg maturation and ovulation.
