High Quantities Of Beer Affect Male Fertility, Study Says


Just four pints of lager a week can harm male fertility, according to a recent Danish study.

The new finding points to an increasing public health concern, especially in the UK, where one in seven couples who have trouble starting a family attribute their problems to male infertility.

The study, conducted by University of Southern Denmark researchers, indicated that young men who drank a little more than three pints a week, or half a pint each day, reduced the quality of their sperm. Researchers noted that the effects occurred when more than 7.5 units of alcohol were consumed each week.

The study involved 1,200 military recruits between the ages of 18 and 28 who were asked about their drinking habits. They were also asked to give blood and sperm samples.

According to the study, most of the men had drunk 16 units of alcohol in the previous week and half of the men had binged on alcohol or had been drunk more than twice in the past month. The men who had drunk more had less sperm, which was more abnormal in shape and size than those who had drunk less alcohol.

While the researchers pointed out that the finding might just be a correlation – meaning that it’s possible that men with poor sperm drink more, instead of the other way around – they noted suggested a ‘high habitual intake’ of alcohol is still inadvisable in terms of infertility.

“I think the main message of this paper is clear,” Chris Barratt, professor of reproductive medicine at the University of Dundee, said. “High levels of alcohol intake do appear to be associated with changes in sperm and semen that may affect infertility.”

Dr. Allan Pacey, a male fertility expert at the University of Sheffield, said that while his own study had failed to link infertility to extreme drinking, the correlation is not unthinkable. Pacey added that binge drinking may be more harmful than the long-term intake of alcohol in the long-run.
