Daily popular science post: Can men really get drunk and have sex?

Drunk promiscuity is one of the topics that people often gossip about. Some people say that this is just an excuse for men to fool around, while others think that men can't get an erection when they are drunk. Predecessors have done a lot of research on this. At present, it seems that if you drink too much at a time, men can still achieve something, but it is difficult to ejaculate; And drinking it for a long time will make you impotent. Some men will say that they are drunk, can't remember clearly, and have no responsibility. Some people retort that a man can't get an erection when he is drunk, so as long as he does, it will prove that he is not drunk at all! Whether a man can "promiscuous" after drinking is an important issue involving science and character. Science vs Personality In a review of Alcohol and Human Sexual Behavior, psychologist Crowe, Dr. Ye Xiaokai C Crowe of new york State University and William H George compiled a lot of relevant information. Among them, some studies (Snyder and Karacan) pointed out that alcoholics have less erections at night, low hardness and slow erection. If there is a problem with erections at night, impotence often occurs. This is consistent with the medical community's general belief that alcoholism will lead to impotence. As early as 1976, farkas and Rosen (Facas &; Rosen) published research in this field. By measuring the circumference of the penis, they found that men with a blood alcohol concentration (BAC) of 0.025 would have a slightly higher sexual response. What is the concept of BAC reaching 0.025? Generally speaking, it is just a few drinks, and the behavior is the same as that of normal people. It's not drunk. But when the alcohol concentration in the blood exceeds 0.05 BAC, men's sexual response will plummet-at this time, they will start talking too much and lose their attention. In 1979, Malatesta, Pollack and others studied the ejaculation of volunteers during masturbation after drinking, and found that when BAC reached 0.06, the time required for volunteers to ejaculate was obviously prolonged, while when BAC reached 0.09, many volunteers could not ejaculate at all. When BAC reaches 0.09, people will become insensitive and only one step away from getting drunk. However, regardless of the ejaculation situation, the researchers found that drinking alcohol has no significant effect on erection-that is, they still have the conditions to "commit crimes". In 2008, a study by the University of Washington also tried to find out the effect of alcohol on male erection. Scholars studied the reaction of 78 heterosexual men to pornographic movies without drinking alcohol and BAC 0.08 by penis plethysmography. Finally, they came to a conclusion "regretfully", that is, on average, there is no significant difference in erectile status between drunk men and men who are not drunk. Judging from erectile function, men are capable of committing crimes after being drunk. As for whether or not to recognize the debt afterwards, it is true or not, which is a matter of personality (embarrassment). The influence of alcohol on sex Even if drinking alcohol does not affect men's erection, alcohol may lead to poor performance in bed. Studies have shown that alcohol can anesthetize cells in male and female reproductive tissues, so it is difficult for both of them to reach orgasm after drinking alcohol. A study by George Wh and Davis KC of the University of Washington shows that it is more difficult for women to arouse sexual desire after drinking a lot. As for men, as mentioned above, they may not be able to ejaculate after drinking to a certain extent-don't think that this can prolong sexual intercourse, and the taste is absolutely unpleasant. Moreover, alcohol will make people slow and clumsy, which will bring a lot of obstacles to passionate moments. If you want to get pregnant, saying goodbye to alcohol has a great influence on pregnancy. This is because alcohol can affect people's liver function and lead to an increase in estrogen levels. For men, this may affect the development of sperm. Moreover, alcohol may also kill spermatogenic cells in the testis, resulting in a decrease in the number of sperm. Therefore, men who often drink alcohol often have low sperm count and poor mobility. For women, drinking alcohol may lead to irregular menstruation and ovulation dysfunction, thus affecting pregnancy. So doctors usually advise couples who want to get pregnant to give up drinking for a while. In short, moderate drinking is really good for your health, and a small amount of drinking beforehand will also make you feel good, but if you are drunk, don't toss about, wash and sleep early.
