Studies have shown that sleep apnea increases the likelihood of sexual dysfunction for both men and women. In addition, the disrupted, restless, and often noisy sleep of a person with OSA—which can include loud snoring—can send sleeping partners to separate beds. Not good for intimacy.
Researchers at Walter Reed National Military Medical Center have found that regular CPAP use can improve both sexual function and sexual desire among men with obstructive sleep apnea. Their study examined erectile function and libido among 92 men who’d recently been diagnosed with sleep apnea and were using CPAP therapy. All the men were under the age of 60—their average age was 45—and none were diabetic. Researchers testing the men at the outset of the study found that nearly 50% of the 92 participants were suffering from some degree of erectile dysfunction. This is not surprising—we know that men with sleep apnea are also significantly more likely to suffer from ED than men without sleep apnea.
Researchers evaluated the men at 1, 3, and 6 months after beginning CPAP therapy. They found that all the men experienced improvement in both erectile function and libido as CPAP treatment progressed. The men who had been diagnosed with erectile dysfunction at the beginning of the study experienced the most significant improvement to their sexual function and desire. But even the men without ED saw improvements to their libido and sexual function after using the CPAP to treat their sleep apnea.
