Experts are beginning, slowly, to decipher what low testosterone levels are, and how this influences a man’s general health. Implications have already been found on some devices and systems, so that future studies are to be pursued in the hope that such information will be much larger and will assist patients.
Testosterone is a steroid hormone secreted by the testes in men (mainly) and adrenal glands (in smaller amount), in women. Its role is important ever since the intrauterine period, when involved in sexual differentiation in genital development of the prostate and seminal vesicles. In postnatal life, namely childhood and pre-puberty, testosterone is important in bone growth, accelerated bone maturation, development and stimulating of the sebaceous glands in both boys and girls.
The maximum secretion of testosterone begins to be reached after the body reaches puberty. During this period testosterone is responsible for the emergence and maturation of secondary sexual characteristics, for auxiliary hairiness appearance, body, and facial, pubic, to increase the size of the penis and to stimulate the development of seminal tissue (thereby influencing fertility). In mature body, testosterone maintains all these sexual characters, boosts libido, maintains muscle tone and stimulates mental and physical energy (zur webseite).
Age is one of the factors involved in reduced secretion of testosterone. It seems that after the age of 30 years, the testosterone level decreases by 1-2% annually. This reduction in testosterone is associated with a lower rate of survival. Low testosterone translates clinically mainly in reduced libido by reducing erectile function and increasing the risk of osteoporosis by night sleep rhythm disorders, insomnia, lethargy and mood swings.
Thanks to the very important role of testosterone in the body, many diseases have been linked, over time, with the decrease of secretion and synthesis of testosterone. The most common are diabetes, metabolic syndrome, obesity and hypertension. Although currently it recognizes that not the actual decrease of testosterone itself is the main etiological factor of these diseases and the administration of hormonal products based testosterone is not a cure, experts believe that the reduction in time of this hormone can influence the overall health of the body.
