Experts from America, came to unexpected conclusions. It turns out that alcohol and coffee do not affect the ability of a man to fertilize, and an hour and a half ride on a bicycle leads to a decrease in fertility by 34%.
In Boston, a meeting of the American Society of Reproductive Medicine and the International Federation of Fertility Society. During this meeting, the results of research in this field were presented.
Studies conducted by scientists have shown the effect on the male body of alcohol and caffeine. In the experiment, 166 men participated, who had problems with fertilization. As it turned out, scientists did not find the harmful effects of alcohol or caffeine on the quality of sperm. French scientists conducted a completely different study in this area. They studied the genetic analysis of sperm 4,5 thousand men to find out whether caffeine has a harmful effect on sperm DNA. As it was found out, the use of coffee does not lead to strong damages of DNA of sexual cells at men.
In addition, specialists have studied some types of exercise that can reduce or, conversely, improve the quality of sperm, and, accordingly, affect the fertility of men. According to Audrey Gaskins, who is the author of the work, physical exercises have a positive effect on the quality of sperm. The study involved 137 men who were divided into groups. So in a group where men were exercising an hour a day, it turned out to be 48% more sperm, unlike those who gave exercises less than one hour per week.
Also, scientists managed to find out that some types of physical activity significantly increase the quality of sperm. Men who are engaged in fresh air for about two hours a week in the spermogram are 42% more germ cells, in contrast to those who did not spend much time in the fresh air. Scientists attribute this to the effect of ultraviolet light, which increases the level of vitamin D in the body, which affects the fertility of men.
Similar results were found in men who are engaged in weightlifting, who for more than two hours are engaged in the gym and pump muscles. During the research, it was found that male weightlifters have 25% more spermatozoa than men who do not lift weights. As reported by O. Gaskins, this result is due to the fact that in men who are engaged in weightlifting, the male sex hormone testosterone rises significantly in the body. Also, scientists managed to find an interesting fact - cycling for more than two hours leads to the fact that men's fertility is reduced by 34%. As scientists explain this phenomenon, it occurs as a result of strong pressure on the scrotum and an increase in temperature in the inguinal region.
Earlier, scientists studied the properties of food to influence the quality of male germ cells, and as it turned out, the use of sausages, ham and hamburgers significantly lowers the quality of sperm, which, naturally, affects fertilization.
