How Medroxyprogesterone works
Medroxyprogesterone works by mimicking the natural hormone progesterone in the body.
It helps regulate the lining of the uterus (endometrium), preventing excessive thickening and controlling the timing of menstrual bleeding.
As a contraceptive, it also works by preventing ovulation and thickening the mucus at the entrance of the womb, making it harder for sperm to reach an egg. This combined action helps regulate the menstrual cycle and prevent pregnancy.
