Progesterone |
| Progesterone is a term that is incorrectly used interchangeably to describe both natural bio-identical progesterone and synthetic substitutes. Synthetic progestins (also called progestogens or progestational agents) are derivatives of bio-identical progesterone, and have been developed because they are longer lasting, more potent, and patent able. Although synthetic progestins such as medroxy-progesterone acetate are clearly beneficial in preventing estrogen-induced overgrowth of the uterine lining and endometrial cancer, their other effects are less desirable. Below we see the difference in bio-identical progesterone and Provera® (medroxyprogestone) a synthetic progestin. The synthetic progestins are not the same and they have different actions in the body than the hormones they are intended to replace. Additional Resources: Progesterone resource links |
