A Harvard study of nearly 2,000 men found that abstainers and heavy drinkers were the most likely to become impotent. Erectile dysfunction was the least likely to occur among moderate drinkers.

The results were presented by Dr. Eric Rimm of the Harvard School of Public Health at the annual meeting of the American Urological Association.

These findings are consistent with other studies, which have shown that people who have one or two drinks a day have lower cholesterol and therefore better blood flow. Good circulation is essential for male sexual performance. However, restricted blood circulation is also a cause of sexual difficulties among women.
