Excessive Follicle-Stimulating Hormone (FSH) in hypogonadism indicates gonadal insufficiency. Pituitary function test, useful to distinguish primary gonadal failure from secondary (hypothalamic/pituitary) causes of menstrual disturbances and amenorrhea. Inadequate corpora lutea are related to low FSH levels. Useful in defining menstrual cycle phases in infertility evaluation of women and testicular dysfunction in men. |
