title: Sexual functions of men with obstructive sleep apnoea syndrome and hypogonadism may improve upon testosterone administration: a pilot study.
abstract: This study examined 72 patients with obstructive sleep apnoea syndrome (OSAS), confirmed by polysomnography. Thirty-two patients were suffering from erectile dysfunction (ED) assessed by IIEF-5 questionnaires and confirmed by nocturnal penile tumescence examination. Their testosterone levels were measured. Eight patients had normal testosterone levels and were treated with a PDE-5 inhibitor (vardenafil) only; after 6 months of treatment, 6 of these patients (75%) showed significant improvement in erectile function. The remaining 24 patients with OSAS, ED and hypogonadism (total testosterone <12 nmol l(-1)), were divided into two groups based on the indication for continuous positive airway pressure (CPAP) therapy: five patients received CPAP therapy (group 1) and 19 patients did not (group 2). The patients of group 2 received only a PDE-5 inhibitor (vardenafil 20 mg) for ED; and eight patients (42%) showed an improvement after 3 months of treatment. The five patients receiving CPAP therapy were treated with a combination of parenteral testosterone undecanoate and a PDE-5 inhibitor (vardenafil) and all had normal erectile function after 3 months of therapy. The results suggest positive effects of addition of testosterone to treatment with PDE-5 inhibitors in hypogonadal men with OSAS, which should be confirmed in larger controlled studies.
