Rigevidon

How Does Rigevidon Work?

A woman becomes pregnant when an egg discharged from the ovaries is fertilised by a sperm. Ovulation is the process through which the ovaries release one egg each month during a typical menstrual cycle. Progesterone and oestrogen regulate this process. Rigevidon comprises the synthetic hormones levonorgestrel and ethinylestradiol, which manipulate the levels of each hormone to prevent the release of an egg. The pill makes it more difficult for sperm to reach the uterus. Fertilisation and embryo implantation fail to take place, resulting in a light period.
