PURPOSE: The effects of androgen replacement via a nonscrotal permeation enhanced testosterone transdermal system on the sexual function of men with hypogonadism were assessed. MATERIALS AND METHODS: An open label, multicenter study of testosterone supplementation and withdrawal was conducted with sexual function assessed by the Watts and Davidson questionnaires and RigiScan monitoring. RESULTS: When comparing results obtained during use of the testosterone transdermal system (with normalized testosterone levels) and during the androgen withdrawal period, nocturnal erections occurred more frequently with longer duration and greater rigidity, and patient assessments of sexual desire and weekly number of erections were higher. CONCLUSIONS: Sexual function improved significantly in men with hypogonadism treated with the testosterone transdermal system.
