Estrogen initiates female pubertal development, including breat development, widening of the pelvis, and distribution of body fat.
Together with progesterone, estrogen regulates the menstrual cycle.

FSH, released from the anterior pituitary, acts on granulosa cells in the ovary, inducing their production of estrogen.
