FSH
Follicle-stimulating Hormone
REF: DS177710 96 tests

Intended use
Immunoassay for the in vitro quantitative determination of follicle-stimulating hormone in human serum.

Summary
FSH (follicle stimulating hormone), together with LH (luteinizing hormone), belongs to the gonadotropin family. FSH and LH regulate and stimulate the growth and function of the gonads (ovaries and testes) synergistically. Like LH, TSH and hCG, FSH is a glycoprotein consisting of two subunits (α- and β‐chains). Its molecular weight is approx. 32000 daltons. In women, the gonadotropins act within the hypothalamus‐pituitary‐ovary regulating circuit to control the menstrual cycle. (1, 2, 3)
FSH and LH are released in pulses from the gonadotropic cells of the anterior pituitary. The levels of the circulating hormones are controlled by steroid hormones via negative feedback to the hypothalamus. In the ovaries FSH, together with LH, stimulates the growth and maturation of the follicle and hence also the biosynthesis of estrogens in the follicles. The FSH level shows a peak at mid-cycle, although this is less marked than with LH. Due to changes in ovarian function and reduced estrogen secretion, high FSH concentrations occur during menopause. (3) In men, FSH serves to induce spermatogonium development.
Determination of the FSH concentration is used in the elucidation of dysfunctions within the hypothalamus‐pituitary‐gonads system. The determination of FSH in conjunction with LH is utilized for the following indications: congenital diseases with chromosome aberrations, polycystic ovaries (PCO), amenorrhea (causes), and menopausal syndrome. Depressed gonadotropin levels in men occur in azoospermia. (1, 2, 3, 4, 5)
