Changes in the body, during which there is a gradual transition from puberty to the extinction of sexual function, are due to a decrease in the level of the main male hormone testosterone.
The climacteric period, during which the age-related physiological restructuring of the body takes place, is a natural stage in the life of every person – both men and women. The only difference is that in men menopause is usually milder and begins a little later than in women, that is, at 50-60 years.
With age, a man’s body undergoes natural changes in one of the most important parts of the brain – the hypothalamus, which regulates the activity of the main endocrine gland – the pituitary gland. As a result, the production of hormones by the pituitary gland is disrupted, stimulating the activity of the male sex glands – the testicles.
At the same time, age-related changes are observed in the testes themselves: their tissue is gradually partially replaced by connective and adipose tissue. All of this, taken together, leads to a decrease in testosterone production by the testes.
Testosterone in the male body regulates the activity of the testes, epididymis, se
minal vesicles, prostate and many organs outside the reproductive system. It stimulates sperm pr
oduction and also determines libido, sexual arousal and orgasm intensity.
Of no small importance in the development of male menopause are diseases associated with old age – hypertension, atherosclerosis https://en.wikipedia.org/wiki/Atherosclerosis, diabetes mellitus.
