What is testosterone deficiency?
Testosterone deficiency, often referred to as hypogonadism, occurs when the body produces insufficient amounts of testosterone—a hormone critical for male health. Testosterone is responsible for regulating a range of functions, including muscle mass, bone density, red blood cell production, and libido. Although testosterone is commonly associated with men, women also produce small amounts of this hormone. Testosterone deficiency can result from various causes, including ageing, medical conditions, or lifestyle factors. Leading consultant urologist Mr Jas Kalsi provides a patient-friendly overview of testosterone deficiency, helping you identify potential symptoms and understand its causes and treatment options.
