The testosterone hormone makes most of the

physical changes in a boy.

How does Estrogen cause Physical ChangesSimilar to boys, girls also start from the

pituitary glands and sends the signal through the blood cells to the ovaries. The ovaries contain eggs that have been laying there since she was born. Then it starts to produce a hormone called estrogen. Estrogen also causes most of the physical changes in a girl.
