What is the Origin of Endometrial Protection Progesterone?

The concept originated directly from the clinical observation in the 1970s that estrogen replacement therapy alone increased the incidence of endometrial cancer. Progesterone was introduced into hormone replacement protocols to mimic the natural menstrual cycle's protective phase, establishing a standard of care in women's hormonal health.

What is the Mechanism of Endometrial Protection Progesterone?

Progesterone acts by binding to progesterone receptors in the endometrial tissue, inducing a differentiation process that limits cellular proliferation and promotes glandular maturation. This mechanism effectively counterbalances the mitogenic effects of estrogen, preventing uncontrolled growth. The correct dosing and timing of progesterone are crucial to ensure adequate receptor saturation and subsequent protection of the endometrium.

Endometrial Protection Progesterone

Meaning

The essential clinical practice of administering progesterone to women receiving estrogen replacement therapy to counteract the proliferative effects of estrogen on the uterine lining (endometrium). This intervention is mandatory for women with an intact uterus, as unopposed estrogen can significantly increase the risk of endometrial hyperplasia and carcinoma. Progesterone serves a vital protective role by inducing secretory changes and promoting shedding of the lining.
