Progesterone restores estrogen receptor sensitivity to its original state. Progesterone also protects against the proliferate side of breast cancer in estrogen receptors. It also down regulates DHT through 5 alpha reductase. It has no feminzing effect. Progesterone in the presence of estrogen up-regulates side branching, and estrogen promotes the elongation of breasts. But......an odd spin is that progesterone down regulates it's own receptor.
