Abstract
- From February 1993 to July 1993, serum testosterone concentrations were measured in 297 impotent men as a screening test. Libido was assessed by response to a questionnaire. Testis size was determined using an orchiometer, and atrophy was defined as a testicular volume less than 15mL. Of the 297 patients, 32(10.8%) had low serum testosterone concentrations, but on repeated testing, only 9 patients(3.0%) had an abnormally low value. Five patients had primary hypogonadism and four had secondary hypogonadism. All 9 patients with documented endocrinopathy had decreased libido (7) or testicular atrophy(5). Based on this study, we recommend limiting endocrine screening of impotent men to those who have either decreased libido or testicular atrophy.
