Hypogonadism: cardiometabolism and gonadal function in men

Hypogonadism is a relatively rare condition in men, which increases in frequency as men age, but also as they become less active and gain weight. In the past 20 years, developing knowledge on the relationship between hypogonadism and cardiovascular and cerebrovascular health and on aspects of metabolic health has become clearer. The relationship between hypogonadism and specific endocrine abnormalities of spermatogenesis is much longer established. Long- and short-term testosterone replacement therapies have well-recognised effects on cardiovascular and cerebrovascular health and on aspects of metabolic health. This leads to a sense of safety when it comes to considering these options as ways of managing the recognised symptoms of hypogonadism and the hidden adverse findings. That confidence has yet to be proven by long-term randomised controlled studies. The use of exogenous gonadotrophins to raise endogenous testosterone levels is a cost-efficient method of achieving spermatogenesis but is not suitable for long-term testosterone maintenance therapy.
