Progesterone
Progesterone is a steroid hormone of the class of hormones called progestogens. This hormone occurs naturally in the human body. It plays a role in the female menstrual cycle and gestation in pregnancy, as well as taking part in the fertilization of the egg and embryo development during pregnancy. Other roles of progesterone include acting as an anti inflammatory agent, regulating the immune response, normalizing blood clotting, and preventing endometrial cancer by regulating the effects of estrogen in the female body.
If the human body does not produce enough progesterone in the female on its own, there are some effects. For example, progesterone helps to lower estrogen levels, so too low progesterone levels can lead to increased PMS symptoms and difficult periods for women. The woman may also experience mood swings and irritability.
