Follicle stimulating hormone (FSH) is a hormone synthesized and secreted by gonadotropes in the anterior pituitary gland. In the ovary FSH stimulates the growth of immature Graafian follicles to maturation. As the follicle grows it releases inhibin, which shuts off the FSH production. In men, FSH enhances the production of androgen-binding protein by the Sertoli cells of the testes and is critical for spermatogenesis. FSH and LH act synergistically in reproduction.

Follitropin is a glycoprotein pituitary hormone, which is under complex regulation by hypothalamic gonadotropin releasing hormone (GnRH) and by gonadal sex hormones, estrogen and progesterone in females, and testosterone in males. FSH acts on the granulosa cells of the ovary and the Sertoli cells of testis. Normally FSH increase occurs at an early stage of puberty, 2-4 years before LH (Luteinizing Hormone) reaches the same levels. Excessive FSH increase occurs at an early stage of puberty, 2-4 years before LH reaches the same levels. Excessive FSH and LH are found in hypogonadism, anorchia, gonadal failure, complete testicular feminization syndrome, menopause, Klinefelter syndrome, alcoholism, and castration. FSH and LH are pituitary products, and are useful to distinguish primary gonadal failure from secondary (hypothalamic/pituitary) causes of gonadal failure, menstrual disturbances and amenorrhea. It is useful in defining menstrual cycle phases in infertility evaluation of women and testicular dysfunction in men. Both FSH and LH are low in pituitary or hypothalamic failure. FSH and LH are high following menopause. Source: LOINC partner 1
