How norethisterone enanthate works

Norethisterone enanthate contains a synthetic form of the female sex hormone, called progesterone. This hormone stops you getting pregnant by working in three ways: firstly, by preventing an egg being released from your ovaries; secondly, by making the fluid (mucus) in your cervix thicker, which makes it more difficult for sperm to enter the womb; and thirdly, by preventing the lining of your womb thickening enough for an egg to grow in it.
