Maybe it's not the best vitamin in the world, but…
Alcohol and caffeine do not affect male fertility
HealthDay News: Exercise Might Boost Men's Sperm Counts, Study FindsAccording to recent scientific studies, certain types of physical exercise can increase or decrease the quality of sperm, and therefore affect the chances of a couple conceiving a child.
In addition, scientists have found that coffee and alcohol do not affect the ability of men to fertilize. The results of the research will be presented this week at a joint meeting of the International Federation of Fertility Societies (IFFS) and the American Society for Reproductive Medicine (ASRM) in Boston: Impact of Caffeine Alcohol and Exercise on Sperm Quality.
According to lead author Audrey Gaskins from Harvard University (USA), the results of a survey of 137 participants in the experiment showed that men who regularly exercised for one hour every day had 48% more sperm in the samples compared to those who gave them less than one hour a week.
Scientists have also found that certain types of physical exercise can significantly improve the quality of sperm. It turned out that men who engaged in physical activity in the fresh air for more than an hour and a half every week had 42% more spermatozoa in the spermogram than those subjects who did not actively spend time outdoors. Scientists believe this is due to the fact that under the influence of sunlight in the body increases the level of vitamin D, which affects male fertility.
Similar results were shown by weightlifters who pump muscles for two or more hours a week. According to the researchers, weightlifters had 25% more germ cells in their sperm samples than men who did not lift weights. According to Gaskins, this is due to the fact that weightlifting significantly increases testosterone levels in the male body.
In addition, Gaskins and colleagues found that cycling for more than an hour and a half can reduce male fertility by 34%, which, according to scientists, can be explained by pressure on the scrotum and an increase in temperature in this area during this sport.
Two other studies presented at a conference in Boston examined the effects of caffeine and alcohol on the male body. In one of these studies, the effects of alcohol and coffee on the body of 166 men who had fertility problems were studied. "We found that neither coffee nor alcohol harm the quality of sperm," HealthDay quoted the words of the main author of the work, Dr. George Chavarro from Harvard University.
In another study, French scientists conducted a genetic analysis of the sperm of 4,500 men to find out whether caffeine harms sperm DNA. The results of this experiment showed that coffee consumption does not cause significant damage to the DNA of male germ cells.
The results of these studies are presented at a medical conference, therefore, before publication in peer-reviewed scientific journals, all data and conclusions should be considered preliminary.
