The hormone estrogen is more prevalent in girls. Estrogen is a group of hormones that play a significant role in the normal sexual and reproductive development in women. It is primarily produced by the ovaries, although small amounts are also produced by the adrenal glands and fat cells.
Estrogen is responsible for the development of female secondary sex characteristics, such as breast growth, widening of the hips, and the regulation of the menstrual cycle. It also plays a crucial role in pregnancy, childbirth, and bone health.
