ESTROGEN

Estrogen is one of two sex hormones commonly associated with females. Along with progesterone, estrogen plays a key role in your reproductive health. The development of secondary sex characteristics (breasts, hips, etc.), menstruation, pregnancy, and menopause are all possible, in part, because of estrogen.

Estrogen plays an important role in other body systems, too. For this reason, although females have the most estrogen, everyone makes this hormone.
