This is evidenced by both clinical observation and physical and chemical analysis of the effects of alcohol on human physiology. The raw material of male androgen is testosterone, after alcohol enters the human body, it directly inhibits the secretion of testosterone, which causes the level of male androgen to drop linearly. In addition, there is also free testosterone in the body, which is dissolved in the blood. After alcohol enters the body, the level of free testosterone can be rapidly decreased and inactivated, and the level of estrogen in the human body will rise. This is in line with the Chinese medicine theory that the liver and kidney are homologous and that alcohol can damage the kidney essence and kidney qi, which in turn can cause a decrease in sexual and reproductive capacity. However, some patients may feel that their sex life is longer and more exciting after drinking alcohol, but this is a misconception. The improvement in the quality of sex life is only superficial and temporary, precisely because the drinking and the environment at that time increase the sexual desire, and at the same time, the central nervous reaction decreases due to the anesthetic effect of alcohol, which delays the time of ejaculation, but the damage to the human body also occurs at the same time. The damage to the human body from alcohol occurs only after several years of continuous drinking, and clinically, men who have been addicted to alcohol for a long time have different degrees of damage to their sexual function.
