Answers
A hormone made in the pituitary gland. In females, it acts on the ovaries to make the follicles and eggs grow. In males, it acts on the testes to make sperm. Also called follicle-stimulating hormone and follitropin.
Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of women's ovaries and men's testes. In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production.
FSH plays an important role in sexual development and functioning. In women, FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries. FSH levels in women change throughout the menstrual cycle, with the highest levels happening just before an egg is released by the ovary.
Before puberty - 0 to 4.0 mIU/mL (0 to 4.0 IU/L) During puberty - 0.3 to 10.0 mIU/mL (0.3 to 10.0 IU/L) Women who are still menstruating - 4.7 to 21.5 mIU/mL (4.5 to 21.5 IU/L) After menopause - 25.8 to 134.8 mIU/mL (25.8 to 134.8 IU/L)
What having high FSH levels mean? An elevated FSH indicates diminished ovarian reserve. Diminished ovarian reserve is associated with a reduced number of follicles or eggs, often of questionable quality.
