Clinical Significance
The FSH pediatrics by ECL assay quantitatively measures FSH in human serum. In the female, FSH stimulates follicular growth, prepares ovarian follicles for action by LH and enhances the LH induced release of estrogen. FSH levels are elevated after menopause, castration and in premature ovarian failure. In the male, FSH stimulates seminiferous tubule and testicular growth and is involved in the early stages of spermatogenesis. Oligospermic males usually have elevated FSH levels. Tumors of the testes generally depress serum FSH levels and increase levels of LH. High levels of FSH in men maybe found in primary testicular failure and Klinefelter syndrome. Elevated levels are also present in cases of starvation, renal failure, hyperthyroidism and cirrhosis.
