FSH (Follicle Stimulating Hormone)

FSH (Follicle Stimulating Hormone) is a hormone, released from the anterior pituitary gland. It is a gonadotropin, stimulating the ovary to produce hormones and ovulate. 

FSH causes an ovarian follicle to develop and drives the pre-ovulatory rise in estrogen.

There is spike of FSH coincidental with the LH surge. These lead to ovulation within a few hours.

Elevations found in:

  • Ovulation
  • Ovarian failure
  • Testicular Feminization Syndrome

Decreases found in:

  • Polycystic Ovary Syndrome (PCO, Stein-Levinthal Syndrome)
  • Amenorrhea-Galactorrhea Syndrome
  • Pituitary failure
