If you have sex after drinking, beware of impotence.

　　It is well known that drinking alcohol can harm the body, but most people may not know how it harms the body. Appears after long-term drinking and sexual intercourse Impotence , after all, entering the body will produce a series of adverse reactions, and can also cause the decline of sexual ability and even cause impotence. So how exactly does alcohol cause impotence?
　　
　　1. Alcohol vs. nerve The impact of the system
　　
　　Drinking alcohol will briefly excite the "command" of the cerebral cortex, but it will soon turn into a suppressed state. If you have sexual intercourse in a hurry during this short period of excitement, you will be overly excited, reckless and rude, or even lose your temper. Your sexual ability will easily deviate, and you will easily attract blame from your spouse. This often lays the foundation for impotence caused by poor mental and psychological conditions. If sexual intercourse turns from excitement to inhibition, since the nervous system that controls sexual ability is in an inhibited state, the emergence of impotence is more reasonable.
　　
　　2. Effects of alcohol on the vascular system
　　
　　Just after drinking, people will feel hot and flushed on the face, because a large amount of blood is concentrated in the brain and skin Inside the blood vessels, if you have sex at this time, the sexual organs will immediately need a large amount of blood, and the supply will exceed the supply. How can the penis achieve a good erection? When the fever and facial flushing subside, a large amount of blood will accumulate in the internal organs, and the person will feel cold. If there is sexual intercourse at this time, the sexual organs will still not get the ideal blood supply, and impotence will occur.
　　
　　3. Effect of alcohol on sex hormone metabolism
　　
　　Some data show that after drinking a lot of alcohol, the amount of the androgen testosterone in the blood will decrease. On the one hand, this is because alcohol directly hinders the production of testosterone by the testicles, and on the other hand, because under the stimulation of alcohol, the liver will speed up the processing of testosterone, and a lot of testosterone will be broken down and transferred into other substances.
　　
　　Besides, people who drink alcohol for a long time will inevitably develop a certain degree of alcoholic cirrhosis. Although the ability to process testosterone will be weakened, the estrogen level in the body will increase. In short, a decrease in testosterone or an increase in estrogen will cause impotence.
　　
　　4. The impact of alcohol on overall physical condition
　　
　　People who drink alcohol for a long time or are often drunk will show weight loss, fatigue, and loss of appetite. Especially when the alcohol content irritates the gastrointestinal mucosa, it will seriously hinder the digestive function and cause a decrease in nutritional levels. As a result, the overall physical fitness will deteriorate, and sexual performance will also decrease. If impotence occurs, it is not surprising.
