What does the Follicle-Stimulating Hormone test measure?

Q: What is the reference range for Follicle-Stimulating Hormone?

The standard reference range for Follicle-Stimulating Hormone is Females (follicular): 3.5–12.5 mIU/mL; mid-cycle peak higher; postmenopausal: 25–135 mIU/mL; adult males: 1.5–12.4 mIU/mL # REVIEWER FLAG: Reference intervals are sex-, cycle-, and assay-dependent — reviewer to confirm against LabCorp's assay-specific ranges.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Follicle-Stimulating Hormone (FSH) is a clinical biomarker used in female-hormones assessment. Follicle-stimulating hormone is a glycoprotein gonadotrophin secreted by the anterior pituitary under pulsatile hypothalamic GnRH control. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Follicle-Stimulating Hormone?

Follicle-stimulating hormone is a glycoprotein gonadotrophin secreted by the anterior pituitary under pulsatile hypothalamic GnRH control. In women it drives ovarian follicular development and, with LH, regulates the menstrual cycle; in men it supports Sertoli-cell function and spermatogenesis. Its secretion is modulated by negative feedback from gonadal steroids and inhibin, so FSH rises when gonadal function declines. FSH has a longer half-life than LH, making its levels somewhat more stable across the pulsatile cycle.

Why is Follicle-Stimulating Hormone measured?

FSH is central to evaluating ovarian and testicular function and localising the level of a reproductive disturbance. An elevated FSH with low gonadal steroids indicates primary gonadal failure (including menopause), while a low or inappropriately normal FSH with low steroids points to a hypothalamic-pituitary cause. It is a key marker in subfertility assessment, menopausal evaluation, and the workup of delayed or precocious puberty.
