ED from Sleep Apnea is Treatable

manSleep apnea is a common sleep disorder that can cause cardiovascular disease, memory problems, weight gain, headaches and daytime sleepiness that can lead to impairment and danger.

Another important side effect of sleep apnea is the development of erectile dysfunction. For sufferers of sleep apnea, erectile dysfunction (ED) is often part of the package.

New research indicates that ED in cases of obstructive sleep apnea syndrome (OSAS) may be linked to the chronic intermittent hypoxia—oxygen deprivation— (CIH) that patients with OSAS experience during episodes of obstructed breathing.

In the first model to address this possibility experimentally, researchers from the University of Louisville found that after one week of being exposed to CIH similar to that which a human with PSAS would experience, mice showed a 55 percent decline in their daily spontaneous erections.

After five weeks of CIFH exposure, the “latency to mount” period— the average interval between mounting a mate— increased 60-fold.

“Even relatively short periods of CIH…are associated with significant effects on sexual activity and erectile function,” wrote David Gozal, M.D., professor of pediatrics at the University of Louisville.

The results appeared in the second issue for September of the American Journal of Respiratory and Critical Care Medicine, a publication of the American Thoracic Society.

Despite the lingering negative effects of CIH on sexual behavior in mice, the researchers did find that it was largely reversible.

In the second phase of the experiment, Dr. Gozal administered tadalafil, which increases the availability of nitric oxide through PDE5. Treatment with tadalafil improved erectile and sexual functioning in CIH-exposed mice to near-normal levels in almost all cases.

“In the present study, tadalafil restored CIH-induced impairments of latencies to mounts, intromissions and ejaculations, significantly improving performance during spontaneous erections and during mating and noncontact activity,” wrote Dr. Gozal.

“The effects of tadalafil were not limited to the erectile tissue but extended to behavioral components, suggesting a possible role for PDE5 in central nervous system mechanisms that control sexual behavior.”

“Further studies are needed to explore the effects of sleep disruption and episodic hypoxia during sleep on the central nervous system that mediates sexual drive,” said Dr. Gozal.

“Exploration of alternative interventions aiming at preventing and treating this infrequently spoken of, yet extremely frequent complication of OSA, will certainly require improved understanding of the complex mechanisms affecting sexual activity and how it is affected by diseases such as sleep apnea.”

“These findings add sexual dysfunction to a long list of disorders associated with – and probably caused by – OSA,” stated John Heffner, past president of the ATS.

“Although this study was performed in research animals, chronic intermittent hypoxia has profound effects on multiple organ systems and a strong biologic plausibility exists that similar findings will be observed in humans.

“Early identification and effective therapy of OSA is critically important especially considering the high prevalence of this disorder.”
