More than 400 middle-aged patients with impotence were tested for penile blood pressure index. It was found that 53% of patients with organic impotence suffered from arterial damage.

Inadequate arterial blood supply, which causes impotence, is mainly caused by smoking and improper diet. He believes that quitting smoking in these patients can help restore normal sexual function.
The semen quality of 222 married men was examined, of whom 127 were completely nonsmokers and 95 smoked at least four cigarettes per day. The comparison between the two groups showed that the average sperm content in the semen of the smoking group was 25 million per milliliter, while the average sperm content in the non smoking group was 63 million per milliliter; The sperm concentration and percentage of active sperm in the smoking group were significantly lower than those in the non smoking group, accounting for only 49% of all sperm, while those in the non smoking group accounted for more than 63%. Smoking is also a major enemy of eugenics. According to surveys, the incidence of fetal malformations is only 0.5% for fathers who do not smoke, 1.4% for those who smoke 1 to 10 cigarettes per day, and 2.1% for those who smoke more than 10 cigarettes per day. Pregnant women who smoke or smoke passively have a high incidence of low birth weight infants. The birth rate of low birth weight infants in smoking pregnant women is twice that of non smoking pregnant women. Compared with children whose fathers smoke and whose mothers do not smoke, the total risk of leukemia and lymphoma in the former is 20% higher than in the latter, indicating that father smoking is a risk factor. In addition, the children of pregnant women who smoke not only have poor growth and development, but also are prone to defects in intelligence, emotion, and behavior.

Due to active androgens reducing testicular atrophy, impotence can occur.
