Testosterone replacement: when is there a role?
Hypogonadism is an uncommon cause of erectile dysfunction. Unfortunately, hypogonadal states in adult males are difficult to diagnose on purely clinical grounds and it is necessary to seek biochemical support. The simplest way to establish the diagnosis of hypogonadism is by determination of serum testosterone levels. Several methods exist but total testosterone determination plus assessment of sex hormone-binding globulin or bio-available testosterone appear to be the most reliable and accessible. Once a diagnostic of hypogonadism has been established in a man with erectile difficulties, a trial of androgen supplementation is warranted if no contraindications exist. Knowledgeable monitoring is essential. In the absence of an adequate response, co-morbidities should be diligently sought out. In the absence of reliable guidelines for androgen administration to patients with erectile failure, a set of recommendations are provided.
