Healthy adult males contain 60-150 million sperm per milliliter of semen, with an activity rate of over 85% and less than 20% of abnormal sperm. When the number of sperm is too low or the activity rate is low or there are too many abnormal sperm, it can lead to a decline in male reproductive function and even inability to fertilize the egg, leading to infertility.
Smoking can reduce the number and activity of sperm, and increase the incidence of abnormal sperm. Smokers inhale nicotine, which acts on the seminiferous epithelium of the seminiferous tubules that produce sperm, causing a decrease in their spermatogenic function, resulting in a decrease in the number and quality of sperm produced.
Clinical doctors in Australia have found that smokers have an average sperm count of 27 million per milliliter of semen, with an activity rate of 49.27%; 6% of people who smoke more than 20 cigarettes a day have only 100 million sperm per milliliter of semen, which is significantly lower than the basic number required for fertilization, resulting in infertility. In addition, the incidence of varicocele in smokers is 10 times higher than that of non-smokers, which is one of the reasons for reduced sperm motility and infertility.
The fatal harm of smoking to men is to cause impotence. Research has confirmed that long-term smokers can cause embolism of small blood vessels at the end of the human body, including penile blood vessels, resulting in impotence due to poor blood supply to the penis.
Impotence causes couples to be unable to have normal sexual life, which not only leads to infertility, but also affects their relationship, family life, and family harmony. In 1986, the University of Pretoria surveyed 116 impotence patients and found that 108 were smokers. Another survey found that smokers suffer from erectile dysfunction twice as much as non-smokers, but some erectile dysfunction patients can self heal after quitting smoking.
