Follicle Stimulating Hormone

Whenever Puberty is summoned, choose one of
the following:
•If male, act on the Sertoli cells in the testes to
start sperm production and stimulate testosterone production.
•If female, stimulate the growth of ovaries for egg
development and start the menstrual cycle.
This little bugger from the anterior pituitary just loves
to make the lives of teens miserable by starting
acne spurts, mood swings, and periods.
