What are the causes of decreased sexual desire in men?

　　Men can also become sexually apathetic, so what causes men to become sexually apathetic? Generally speaking, the following reasons lead to men’s sexual frigidity:

　　1. Diet:

　　British psychologists recently pointed out that people who are overly particular about the food they eat or who are deliberately dieting may not have as much energy and less strong sexual desire than those who eat casually. At the same time, due to low sexual desire, they often find it difficult to control their diet and overeat, which in turn aggravates low sexual desire and forms a vicious cycle.

　　2. Contraceptive methods:

　　After some women undergo fallopian tube ligation, they experience reduced sexual desire and suppressed sexual impulse due to psychological effects, which can be eliminated through psychological treatment. After a man undergoes vasectomy, the sexual function of the recipient is not affected. The loss of sexual desire in some individuals is also due to psychological factors. Women who use intrauterine devices for contraception may experience reduced sexual desire due to prolonged menstrual periods or increased menstrual bleeding.

　　3. Tobacco and alcohol:

　　Most people who drink a small amount of alcohol (blood alcohol content 20 mg per 100 ml) experience euphoria, activeness, and increased sexual desire. When the blood alcohol content exceeds 40 mg per 100 ml, people will behave clumsily, speak slurred, and have a significant loss of sexual desire. If you drink too much alcohol for a long time, your gonads may be poisoned, leading to male Testicular atrophy and sexual desire decline.
