title: Routine endocrine screening in impotence.
abstract: Routine hormonal screening (serum testosterone and prolactin) of 300 men presenting with a primary complaint of impotence resulted in detection of endocrine dysfunction in 5 men (1.7%). Four patients had hypogonadism, and 1 patient had a prolactin-secreting pituitary adenoma. The cost of screening these men for endocrine dysfunction was $34,722.00. Despite this cost and the low yield of endocrine disease detection, routine determination of serum testosterone and prolactin provides useful information to the clinician evaluating impotent men and when abnormal, indicates the need for thorough endocrine evaluation.
