Experts call testosterone ‘hormone that makes a man out of a man’. Testosterone level largely determines the sexual orientation and men behavior. Sculptural modeling muscles on his broad shoulders, more active metabolism than women's, the ability to procreate… This is not a complete list of testosterone functions in the male body. The normal level of testosterone in men is 11-33 nmol per liter (this figure may vary depending on the method used for testing).
It is believed that the low level is less than 300 nanograms per deciliter of blood. Reduction of testosterone levels passes gradually and very slowly in men by age. There are not very many people with evident symptoms of low testosterone levels. Many preserved sexual activity, but may manifest frequent fatigue, sleep disturbance. Very often, the muscle tissue begins to be replaced by fat abruptly.
Men with reduced in 10-12% level of testosterone, the male sex hormone, are effeminate, soft and sensitive. Conversely, the men with testosterone levels in blood in 10-12% above normal, show aggressiveness, reduced sense of self-preservation.
The functions of testosterone
1. Increase muscle mass
2. Fat Burning
3. Metabolism activation
4. Bone strengthening
5. Protection against cardiovascular and other diseases
6. Provision of secondary sexual characteristics and erection
7. Control of the sperm generation and its ability to fertilize
8. Maintain an increased interest in the female sex
9. Extension of youth and increase the life duration
10. Charging with cheerfulness and optimism
11. Formation of the male character: offensive, active, enterprising, unfettered, fearless, reckless, prone to adventures and improvisations.
Lack of testosterone in men is often caused by age-related changes, or genetic predisposition. Testosterone deficiency is frequent in older men. After adolescence and up to 30 years the androgen level in blood is the greatest. After 30, the level of testosterone decreases slowly in 1-2% annually, and after 50 finally stops and is considered to be passive.
Besides this, the lack of testosterone in men may be related to:
- hazardous or dangerous habits (smoking, alcohol abuse, drugs that completely destroy the hormonal system; so the children of drug addicts have the same testosterone levels as that of the elderly);
- nervous congestion (at work, which is accompanied by stress, family problems, exhaustion of the nervous system, the lack of male emotions);
- the way of life (long-term abstinence, lack of physical activity or immoderate physical activity, use of substandard female products, obese, office mode of life or living in ecologically unfavorable place).
The concentration of free testosterone in blood decreases greatly with age. This is due to the deterioration of blood supply to the testicular tissue. Furthermore, this reduction is associated with the increased levels of globulin, binding testosterone.
It should be borne in mind that the concentration of active testosterone or freely circulating fraction decrease much faster, and total testosterone may be normal. Because of this all symptoms of testosterone reduction is observed in elderly patients, although they have a relatively normal level of it.
Reduced levels of testosterone or hypogonadism lead to a chain reaction in the body. Testosterone is necessary to maintain normal levels of elasticity in the collagen fibers in the cavernous tissue and for the synthesis of nitric oxide, which is indispensable to the normal full erection.
In addition, testosterone is required for normal passage of numerous processes in the body, so reducing its level leads to the development of certain systemic diseases. Somatic diseases, in turn, can trigger changes in hormonal status. For example, chronic prostatitis caused by violations of lifestyle triggers congestion in the small pelvis and can lead to the development of hyper lactogenic factor and the prevalence of estrogen over androgen.
Externally, the decline in testosterone levels is manifested as a decreased libido, ejaculation and orgasm disorders, erectile dysfunction. In addition, there is a decrease in ejaculate fertility. Not less noticeable are somatic disorders such as osteopenia and osteoporosis, gynecomastia, anemia, obesity, reduced physical strength and muscle mass. There are also psycho-emotional disorders.
