Testosterone is vital for healthy characteristics of a man. Deficiency in testosterone can lead to many unwanted side effects in the body such as depression , increased estrogen levels , anxiety , irritability and fatigue. One main cause of low testosterone is age. As men age , the testes produce a lower sufficient amount of testosterone. Testosterone production usually peaks at ages 20 and declines afterwards.

There is a variety of reasons for low testosterone. Damage to the hypothalamus , pituitary gland , and testicles can also decline testosterone production. Elevations of adrenal cortical and high levels of estrogen will also cause feminization , which is counter productive to testosterone enhancement. Smoking , lack of physical activity and excessive drinking will also cause damage to the aforementioned glands , therefore it is important to look at the individual’s style of living to find the cause of low testosterone. Drinking alcohol decreases testosterone while acting as a sexual inhibitor , which is one reason why erection problems arise from excessive drinking.

Lifestyle which can be easily modified by changing ones habits to fit a more healthy and active lifestyle. Aside from lifestyle , genetics can be the backbone for low testosterone , however this is not nearly as important as the hormonal environment and nutrition diet.
