|FSH (Follicle Stimulating
Hormone) is a hormone, released from the anterior pituitary gland. It
is a gonadotropin, stimulating the ovary to produce hormones and
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:
- Ovarian failure
- Testicular Feminization Syndrome
Decreases found in:
- Polycystic Ovary Syndrome (PCO, Stein-Levinthal Syndrome)
- Amenorrhea-Galactorrhea Syndrome
- Pituitary failure
