You just have to turn on the TV to know that there is an epidemic of male sexual dysfunction in America. We are bombarded with ads for medications that improve erectile function and correct low testosterone levels. However, what is rarely mentioned is the relationship of sleep and sleep disorders to sexual function.
Most testosterone is produced while sleeping. The highest levels seem to be produced during REM (dream) sleep. Therefore, it is not surprising that disorders that decrease total sleep or disrupt sleep could affect sexual function. We know that when men are sleep-deprived, their testosterone levels drop. In one study done on military recruits subjected to severe sleep deprivation, their testosterone levels dropped as much as 70%.
Several studies have shown that sleep apnea can cause erectile dysfunction. Moreover, erectile dysfunction has been found to be present in over 60% of men with severe sleep apnea. It is postulated that repetitive drops in oxygen during the night because of airway obstruction is the cause. These drops in oxygen result in endothelial dysfunction. In plain terms, this means the blood vessels that supply the penis lose their ability to regulate blood flow to the organ. This is the basis of most erectile dysfunction. When you combine this with the fact that sleep apnea also depresses testosterone production, is it any wonder that so many men with this disorder suffer from sexual dysfunction?
However, there is good news. When sleep apnea is treated, a majority of men note significant improvement in sexual function. In fact, in one recent study published in the International Journal of Clinical Practice marked improvement was noted after three months of treatment with CPAP (Continuous Positive Airway Pressure).
The take home message here is that sleep and sex are related. In order to maintain good sexual function we need to make sure that we are getting enough sleep and it is of good quality. If you suffer from Erectile Dysfunction and have sleep issues, be sure to discuss them with your health care provider. You may not have to continue taking that ”little blue pill“ after all.
