Overcoming Testosterone Deficiency (TD) begins with diagnosis of the problem. Testosterone levels may gradually decline with age — about 1% per year after age 30. More rapid decline can occur with weight gain, development of sleep apnoea, or pituitary tumours. Testosterone levels vary greatly among men. Blood tests to determine gonadal function and pituitary responsiveness are required to correctly assess the problem. Our clinic provides comprehensive diagnosis and subsidised treatment that can help restore mood, muscle mass, bone health, sexual desire, potency and vigour.
