Good news for coffee drinkers: a few cups a day could help curb men’s risk for erectile dysfunction.

A new study from the University of Texas Health Science Center at Houston found that men who drink more caffeine (the equivalent of about two or three cups of coffee) are less likely to experience erectile dysfunction than their peers who consume little or no caffeine, according to CBS News. Researchers can’t prove causality in this finding, but they suggest the correlation could be true because caffeine helps relax muscles and arteries, allowing freer blood flow.

The finding does not seem to apply, however, to diabetics, who face higher risks of erectile dysfunction.
