Men who are sound sleepers have better sex lives.
A study published in a recent edition of Urology says men who suffer from sleep apnea syndrome also suffer a high rate of erectile dysfunction.
One theory, Dr. Atwood said, suggests that sleep apnea disrupts rapid-eye-movement or REM sleep — a time when men routinely experience erections. Decreased REM sleep means fewer REM erections.
The possibility exists, he said, that REM erections are a necessary process for men to maintain healthy sexual function.
