Why do doctors prescribe progesterone with estrogen?
If you haven’t had your uterus removed, your doctor will typically prescribe estrogen along with progesterone or progestin (progesterone-like medication). This is because estrogen alone, when not balanced by progesterone, can stimulate growth of the lining of the uterus, increasing the risk of endometrial cancer.
What is the role of progesterone in HRT?
In the menstrual cycle, ovarian progesterone protects the endometrium and induces a monthly bleed to reduce the risk of developing abnormal cancerous cells. Combined HRT mimics this protective action only if the progestogen or progesterone is taken at the correct dose and for the recommended number of days.
Is progesterone an anti androgen?
Progesterone is an anti-androgen because it competes with androgens for androgen receptors and an anti-estrogen because it downregulates estrogen receptors (Johnson and Everitt, 1995).
Is injectable estrogen more effective?

Should I take estrogen and progesterone at the same time?

What is the most important estrogen hormone?
Estradiol, an estrane, is the most potent and prevalent. Another estrogen called estetrol (E4) is produced only during pregnancy. Estrogens are synthesized in all vertebrates and some insects. Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history.
Is spironolactone a progesterone?
