> HRT with estrogen and progesterone has been long considered to have anti-aging effects; results of larger studies though, particularly of the Women’s Health Initiative, have shown that an anti-aging effect is not necessarily to be expected. On the contrary, HRT has been accused to have a higher cardiovascular risk and increase of the risk of breast cancer. The Women's Health Initiative studied replacing women's declining hormone levels with horse estrogens (Premarin, derived from PREgnant MARe's urINe) and Provera, the birth-control drug that is used to make women infertile (as the much-loved [1] drug, depot-Provera). Somebody tricked the medical scientists into thinking that Progestins are analogues of Progesterone, except in the case of in vitro fertilization, where they have to use Progesterone USP.
