Progesterone is a hormone released by the ovaries. Changing progesterone levels can contribute to abnormal menstrual periods and menopausal symptoms. Progesterone is also necessary for implantation of the fertilized egg in the uterus and for maintaining pregnancy.
Progesterone inhibits the action of estrogen, hence it is protective against cancer. Progesterone also activates the gene p53, which if inactive or mutated prevents cells from dying naturally. One of the most important effects of progesterone is as a potent diuretic.
