American scientists have made a sad statement for many coffee lovers: only two cups of coffee per day can significantly reduce the reproductive function of men.
Men who abuse this invigorating drink have only one of five chances to become a father with the help of artificial insemination (IVF) of their girlfriends. For those representatives of the stronger sex who are able to limit their craving for coffee to one cup, the chance to see their own child is 52% percent.
According to doctors, caffeine has a negative effect on sperm. It is estimated that one cup of espresso contains about 100 mg of caffeine. Men who consume more than 265 mg of this substance daily have a rather low chance of having an offspring. But beer, drunk in the amount of 750 ml before bedtime, on the contrary, increases the success rate in conceiving a child.
According to doctors, a reasonable amount of alcohol can not only reduce the stress experienced by a man, but also increase the likelihood of procreation. The observation was attended by 105 men, whose average age was 37 years. Wives of volunteers went through IVF. The study, conducted over 6 years, showed that, despite the fact that alcohol and caffeine in general do not affect the number of sperm produced or their speed of movement, the latter dramatically increases the risk of developing male infertility.
