Erectile dysfunction and testosterone deficiency syndrome: the "portal to men's health".

Erectile dysfunction (ED) and testosterone deficiency syndrome (TDS) are closely related. In addition to affecting men's sexual health, both conditions also affect other male health issues. Screening for ED, especially in younger men, should become standard clinical practice for the primary care physician. Possible systemic effects and associated effects of TDS are now well documented. Testosterone replacement therapy (TRT) is very safe and effective in the right man.
