Research has shown that severe obstructive sleep apnea (OSA) has been associated with sexual dysfunction. A recent study from the Mayo Clinic in Rochester, Minnesota published in the Journal of Sexual Medicine (Vol. 5, No. 4, 2008, p. 898) assessed whether milder forms of sleep disordered breathing (SDB), such as snoring, can lead to sexual problems.

Snoring Decreases Sexual Satisfaction

The researchers surveyed 827 men with a regular sexual partner concerning their sleep and sleep habits, as well as questions about their libido, erectile and ejaculatory function, sexual problems and sexual satisfaction.

The subjects were divided into three groups based on the severity of their snoring (Heavy Snorers (N=95), Moderate Snorers (N=573), and Mild/No Snorers (N=159)). Their median age was 64 years (range 51-90 years).

The study showed that sexual satisfaction was significantly lower in the heavy snoring group compared to the other groups. Additionally, heavy snorers were more than twice as likely to report low sexual satisfaction compared to the non-snoring group.

This finding underscores the fact that milder forms of SDB (snoring) can significantly interfere with sexual activity in middle-aged men.

Too Tired for Sex

Other studies and surveys have reported similar findings in the past. The National Sleep Foundation 2005 Sleep in America poll (www.sleepfoundation.org) found that 33% of partnered adults reported problems in their relationships because of their partner’s sleep problems.

Nearly a quarter of those polled stated they have sex less often or have decreased interest in sex, because they are too sleepy. The poll also found that 31% of partnered adults take precautionary measures to prevent their own sleep from being interrupted by the troubled bed partner. Most of these “home-remedies” included sleeping in separate bedrooms or on the couch in another room, which may reduce the likelihood of intimacy.

Apnea, Hypertension and Diabetes May Cause Erectile Dysfunction

Erection is achieved through a combination of psychological, neural, hormonal, and vascular factors. A problem in any of these factors can lead to erectile dysfunction (ED). SDB is a well established cause of hypertension and diabetes, both of which reduce sexual function and interest. Sleep apnea results in reduced blood oxygen supply and frequent sleep interruptions which are known to affect blood vessels and hormone levels that can cause ED.

Treatment of Sleep Disorders Improves Function

By treating an underlying sleep disorder (like SDB), it is possible to improve sex drive and sexual satisfaction. Snoring, sleep apnea, and other sleep disorders can be identified and remedied by a sleep specialist. A survey from Great Britain showed that 63% of respondents reported that they would increase amorous activity if snoring stopped. Clearly, there is more to gain than simply a good night’s sleep by removing snoring and other sleep disorders from the bedroom.
