A steroid hormone, testosterone is found mostly in men. It has a huge role in developing the male reproductive tissues which include the prostate and testes. It promotes other sexual characteristics such as hair growth, bone mass and increased muscle in men. This hormone is vital for a person’s well-being and health and it prevents osteoporosis.
According to a study made by a researcher at the University of Sydney, the decline of testosterone does not only happen with age because older men with great health can actually sustain their hormone levels. Its decline can be because of illnesses acquired due to age such as diabetes, heart diseases and obesity.
Other secondary reasons are beta-blockers and medications for stress, inflammation and hypertension, alcohol consumption, innutritious food, lack of proper sleep, no regular exercise, adrenal fatigue and a genetic disorder called Klinefelter’s syndrome. This disorder happens in one among five hundred men where there is an additional X chromosome in their bodies.
