title: [Andropause].
abstract: The terms andropause, partial androgen deficiency of the aging male (PADAM) or late-onset hypogonadism (LOH) describe a clinical entity which has been defined as a syndrome associated with advanced age. This syndrome is characterised by a deficiency in serum testosterone levels that may result in significant alterations in the quality of life and adversely affect the function of multiple organ systems. Whereas in classic primary and secondary hypogonadism, the clinical picture of testosterone deficiency is clearly defined, the clinical diagnosis of PADAM might escape detection for various reasons: not all signs and symptoms necessarily present together; they often progress slowly and are subtle in nature; the non-specific signs and symptoms might not be discernible from the unavoidable process of aging itself. However, PADAM features many potentially serious consequences that can be avoided or treated, and is, therefore, clinically relevant. Testosterone substitution may be an effective way to manage this condition. Once patients begin treatment with testosterone substitution, follow-up and monitoring are essential.
