Fertility Prevention
Oestrogen can prevent the release of an egg - when oestrogen levels are high, it inhibits the production of FSH and after a while egg development stops and stays stopped
Progesterone stimulates production of thick cervical mucus which prevents sperm getting in
The pill is a mixture of high levels of oestrogen and progesterone
