What effects do testosterone, progesterone and estrogen have on the reproductive system?

Progesterone acts as a combatant to its own receptor, while testosterone acts as an enhancer of sex drive. Estrogen, on the other hand, can sometimes act in the opposite way, primarily because it is recognized to have contraceptive properties.

Testosterone, progesterone, and estrogen play crucial roles in the reproductive system. Testosterone is essential for the development and maintenance of male reproductive tissues, including the testes and prostate gland. It stimulates spermatogenesis and promotes the development of secondary sexual characteristics in males. Progesterone helps prepare the uterus for pregnancy by thickening the uterine lining and maintaining it during pregnancy. Estrogen is important for the development and regulation of the female reproductive system, including the menstrual cycle, ovulation, and the development of secondary sexual characteristics. It also helps maintain the health of the vaginal epithelium and the uterine lining.
