What is the function of FSH?
stimulates maturation of ovarian follicles
support sperm maturation and supports function of Stertoli cells
how is LH and FSH regulated?
by pulses of GnRH
What is the negative feedback for GnRH?
sex steroids inhibit secretions of GnRF, which have negative effects on gonadotrophs
What are the symptoms of low FSH and LH in men?**

in the stomach
stimulates appetite
What is CCK?
found in duodenum, jejunum (I cells
feeling of satiety, reduces appetite
What is secretin?**
