Androgen replacement therapy in the hypogonadal ageing man

In men, gonadal function is affected in a slow, progressive way as part of the normal ageing process. Recently, however, significant interest has developed on the importance of this condition, which is variously known as male climacteric, andropause or, more appropriately, androgen decline in the ageing male (ADAM). The term andropause is biologically wrong and clinically inappropriate but, it adequately conveys the concept of emotional and physical changes that, although related to ageing in general, are also associated with significant hormonal alterations. The inappropriateness of the term is based on the fact that in women, the reproductive cycle invariably ends with ovarian failure. In men, this process is not universal and when it occurs it is normally subtle in its clinical manifestations. This has led to a tendency to ignore the syndrome as an unavoidable and untreatable result of the ageing process. For the sake of simplicity and directness, this review will use the terms ADAM and andropause to denote the global hormonal alterations associated with ageing.
