Guidelines on the management of sexual problems in men: the role of androgens
British Society for Sexual Medicine
The role of androgens in maintaining wellbeing in men is well established. Low androgen levels in men are chiefly the result of hypogonadism. Hypogonadism (primary or secondary) can occur at all ages, including in elderly men.
The diagnosis of treatable hypogonadism requires the presence of symptoms and signs suggestive of testosterone deficiency, as well as biochemical evidence. The symptom most associated with hypogonadism is low libido. Other manifestations include: erectile dysfunction, absence of morning erections, delayed ejaculation, decreased muscle mass and strength, increased body fat, decreased bone mineral density and osteoporosis, decreased vitality, and depressed mood.
This Guidelines summary covers laboratory testing, types of interventions and treatments, and follow-up and monitoring.
