Estrogen is a female hormone
It is not a hormone that only prevents women, but it does play an important role in the development of female sexual characteristics, in the menstrual cycle and in a pregnancy. Estrogen is also found in the male body, but the usefulness is still unclear. Excess estrogen in the body can inhibit sexual desire. Estrogens play an important role in the growth of the uterus, the breasts and the vagina.
