Answer

LH and FSH deficiencies may indicate secondary hypogonadism. Elevated FSH and LH levels differentiate primary hypogonadism from secondary hypogonadism. A low testosterone level in a man, or an amenorrheic woman with low estradiol and low/normal serum FSH/LH, indicates secondary hypogonadism.
