The fact that human male sexual responsiveness declines with age is unquestionable. However, the sexual responsiveness of older men varies from person to person and from time to time for a particular individual. Acute or chronic physical illnesses, the social environment in which they live, and many other physical and psychological factors can have an impact on it. Summarized in the following five categories 1, sexual activity monotonous and boring, resulting in loss of interest in sexual intercourse; in addition, women after menopause, whether from the appearance or physiological rapid decline, can also make men lose sexual interest. 2, mental and physical fatigue fatigue is an important factor in the decline of sexual desire, and in middle age after the performance of the increasing impact. 3, diet, drinking too much Older men have a tendency to inhibit sexual tension by eating too much or drinking too much for a long time. 4, physical and mental illnesses The possibility of disease suddenly rises after age increases, acute illnesses caused by reduced sexual demand is often temporary; if the body’s disease develops into chronic, sexual function decline is one of the early signs of reduced physical performance. For example, diabetes mellitus is accompanied by a high percentage of impotence. On the other hand, the sexual life of older men is restricted due to the long-term illness of their wives, which can also lead to low sexual responsiveness or even loss. 5, fear of failure Any of the above points can cause fear of sexual performance incompetence in older men, and once impotence occurs in a situation, many men voluntarily retreat from any sexual activity species rather than face up to it and seek medical help. There are various reasons to believe that the ability to maintain regular sexual expression in the face of the aging process, coupled with proper physical health and a sound psychological state, sexual expression may be extended to the advanced age of 80.
