Does smoking affect male sexual performance?

　　Two years ago, the "Thalidomide" incident in Western Europe resulted in the birth of tens of thousands of children with seal-like deformities. After this tragedy, people began to understand the teratogenic effects of drugs or various chemicals. Since then, people have gradually realized that pregnant women should not smoke, and doctors have always warned women who are pregnant or want to become pregnant to stop smoking. However, smoking is good for male No one pays attention to its impact on reproductive function. I am afraid that most men have little understanding of its harm. Many young men will ask the doctor during premarital examination: "I smoke very hard, are there any problems in my lungs?" ”Because everyone knows that smoking may cause lung cancer, but no one asks whether smoking will affect sexual function and fertility! This is because they do not yet understand the harm that smoking brings to fertility and sexual performance.

　　Paris "Europe Impotence Research Center" once measured the penile blood pressure index of more than 400 middle-aged impotence patients and found that 53% of patients with organic impotence had arterial and vascular damage. Furthermore, other factors ultimately cause damage by affecting the arteries that carry blood. It is well known that smoking can cause arteriosclerosis. Research results show that 2/3 of impotence patients smoke. After investigation, a French doctor believed that the insufficiency of arterial blood supply that causes impotence is mainly caused by smoking and improper diet. He suggested that these patients quit smoking and drink less alcohol, which would help restore normal sexual function. Peking University Peking University Hospital Andrologists have made similar observations. Research also shows that smoking among male adolescents will delay the maturation of male sexual characteristics.

　　Doctors found in infertility clinics that smokers are normal sperm The number has decreased, by about 10% on average. Those who smoke 21 to 30 cigarettes a day have a significantly higher incidence of abnormal sperm. ； Those who smoked more than 30 cigarettes had a higher incidence of abnormal sperm. The longer you smoke, the more abnormal sperm will be, and as the number of normal sperm continues to decrease, sperm motility will also weaken. According to analysis, this is probably because the toxic substances in smoke act in the body, damaging the genes that regulate sperm production, and then changing the sperm morphology. Someone once analyzed more than 5,000 pregnant women and found that those whose husbands smoked more than 10 cigarettes a day, fetus Prenatal mortality has increased significantly； The more you smoke, the higher your mortality rate. Women whose husbands smoke are about 2.5 times more likely to give birth to children with birth defects than those whose husbands do not smoke. Therefore, the harm of men's smoking to fertility and sexual ability is quite serious.
