Testosterone deficiency in adult men
Based on the British Society for Sexual Medicine Guidelines on adult testosterone deficiency, with statements for UK practice1
Testosterone is the most important androgen in men. It regulates a number of vital processes in the body and is responsible for the development and maintenance of secondary male characteristics.2
When testosterone levels fall, patients can experience adverse physical and psychological effects, and a subsequent reduction in quality of life.3
Testosterone deficiency (TD) is defined as a clinical AND biochemical syndrome, associated with advancing age and comorbidities, characterised by a deficiency in serum testosterone PLUS relevant signs and symptoms.3,4
