- Sample Type
- Standard
- Fasting

FSH is a gonadotropin synthesized and secreted by the anterior pituitary gland. In females, it stimulates the growth of ovarian follicles and estrogen production. In males, it acts on Sertoli cells to support spermatogenesis. In the context of the 'LH, FSH, PRL Profile', it is used to diagnose primary vs. secondary hypogonadism, evaluate infertility, investigate menstrual irregularities, and confirm menopause.

Why Context Matters
FSH levels fluctuate wildly during the menstrual cycle; a single measurement without clinical context (day of cycle) is often uninterpretable. Furthermore, biotin supplements or high doses of exogenous hormones (BCP) can interfere with immunoassay results.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
