Follicle Stimulating Hormone

Alias: FSH

Discipline: Clinical Chemistry

Test information: In females, FSH stimulates follicle development and production of oestradiol and other oestrogens during the follicular phase of the menstrual cycle. FSH acts synergistically with LH to cause ovulation. In males FSH stimulates spermatogenesis. Increased concentrations of the gonadotrophins are seen in ovarian failure in women, whether pathological or after the natural menopause. High concentrations of FSH are seen in azoospermic men and LH is increased if testosterone secretion is decreased.
