Hypogonadism

Men gradually reduce their levels of testosterone as they age. Many of the signs and symptoms of testosterone deficiency were previously believed to be part of the normal ageing process, and only recently has treatment of low testosterone in the ageing male been shown to provide long-term physical and mental improvement. There is an estimated UK incidence of 8% of men aged 50€“79 years with testosterone deficiency syndrome, also known as hypogonadism.
