Answer 1

Estrogen leads to the growth of breasts at puberty along with other female secondary sexual characteristics, including the distribution of body fat and the development of reproductive organs.

During puberty, in addition to breast development, estrogen is responsible for the growth of the uterus and ovaries, initiation of the menstrual cycle, and the deposition of fat in areas like the breasts, hips, and buttocks. It also contributes to the growth of axillary and pubic hair. Estrogen does not cause increased larynx size or a deepening of the voice; those are effects of testosterone in males.
