The three main things that control the female brain?
Ha.
You thought this was the beginning of a joke, didn’t you?
It’s not.
They are:
1. Estrogen
2. Progesterone
3. Prolactin
Be ignorant at your own peril.
The primary hormones that exert control over a girl’s brain are estrogen, progesterone, and prolactin. Michael Gurian gives a detailed, insightful account of the science behind brain development in his book, The Wonder of Girls. This is our summary:  Estrogen is the nesting hormone. It helps a girl/ woman feel content with herself, her relationships, and her life.  Progesterone is the reassurance hormone. It creates more of a need for connection and a need for that connection to be reinforced —often.  Prolactin is the inviting hormone. Girls have 60 percent more of this hormone than boys. Basically, this hormone creates tear glands. It causes girls to cry, engendering empathy and inviting deeper connection.
