First, alcoholism and impotence Because of the long-term abuse of alcohol and alcoholism in men, about 50% suffer from sexual dysfunction. Among male alcoholics, about 40% have erectile dysfunction; 5% to 10% have ejaculation disorders. In the months or years after quitting alcohol, sexual function returns to normal in only half of these cases. 1, why alcoholism will cause sexual dysfunction? Alcohol’s effect on the nervous system Drinking alcohol will briefly excite the cerebral cortex, but then it will turn into a state of inhibition. If you rush to have sex at this time, you will be too excited, reckless and rude, or even out of order, sexual behavior is prone to deviation, but also prone to incur the blame of the spouse, which is often due to poor mental state caused by erectile dysfunction to lay the root of the trouble. If you have sexual intercourse after the change from excitement to inhibition, erectile dysfunction is more likely to occur due to the inhibition of the nervous system that controls sexual ability. Alcohol’s effect on the vascular system After drinking alcohol, people will feel a burst of heat, facial blush, at this time the blood of the whole body is mainly concentrated in the brain and the skin inside the blood vessels, if sexual intercourse at this time, there will be a lack of blood supply in the corpus cavernosum of the penis, can not be a good erection, and when the fever and the facial blush subsides, a large amount of blood will be stagnant in the internal organs, but people feel chilled, so then have sexual intercourse, the corpus cavernosum of the penis is still not an ideal blood supply, so the spongy penis is still not ideal. Still do not get the ideal blood supply, so erectile dysfunction will occur. 2, the effect of alcohol on the metabolism of sex hormones After drinking a lot of alcohol, will not only make the blood androgen reduction, will also make the body estrogen level rise. Both results will cause erectile dysfunction. Alcohol on the physical condition of the impact of long-term drinking or often drunk people will show thin, fatigue, loss of appetite, especially after the alcohol content to stimulate the gastrointestinal mucosa, will seriously hamper the digestive function, caused by the decline in the level of nutrients, so the overall physical condition is deteriorating, the sexual ability will also decline. Erectile dysfunction can easily occur. So people who may have erectile dysfunction should never abuse alcohol. Second, smoking and impotence Smoking can make the blood supply of penile arteries affected. Foreign people have done a test: the dog will be anesthetized, through the electrical stimulation to make its penis erect. At this time, with a special device to simulate the situation when people smoke, the smoke of different cigarettes sprayed to the dog’s nose, respectively, recorded the dog penile cavernous artery blood flow changes. It was found that despite the different types of cigarettes used, they all reduced the blood flow in the cavernous artery of the dog’s penis to varying degrees. This experiment objectively proves the fact that smoking does reduce blood flow in the cavernous arteries of the penis, thus affecting the quality of erections. Therefore, we advise those who are addicted to smoking, especially those who have erectile dysfunction at the same time, should quit smoking as soon as possible.
