Testosteron und erektile Dysfunktion

Primary hypogonadism represents a classic but rare cause of erectile dysfunction (ED) in men. Therapy with testosterone as monotherapy is therefore unlikely to cure ED in the typical ED patient. However, recent developments indicate a much greater role of testosterone in erectile function than has been supposed in the past. Serum testosterone levels decline in men with increasing age. Aging men might develop late-onset hypogonadism (LOH) associated with characteristic symptoms. Typical symptoms of LOH are represented by decreased libido and sexual function, osteoporosis, altered distribution of body fat, overall reduction in physical strength, and alterations in the general mood. Experimental and clinical studies over the last few years have also pointed out that hypogonadism results in characteristic alterations of the erectile tissue of the penis. These alterations might be reversible in response to hormone therapy with testosterone. Particularly testosterone might be a helpful supportive therapy in cases where PDE-5 antagonists have tended to lose their effectiveness on the erectile tissue in the treatment of ED.
