A correlation has been found between erectile dysfunction and sleep apnea—also known as sleep disordered breathing (SDB).
A past article in Urology Today states:
“Since the majority of physicians who treat ED are unlikely to have expertise in SDB, and similarly those who treat SDB generally have little expertise in diagnosing or treating ED, it is the opinion of the authors that the potential impact each of these conditions may have on the other has been greatly underestimated. This review article attempts to alert physicians of the interaction between two apparently different disorders and give a more unified approach of ED and SDB.”
Vasculogenic, neurogenic, hormonal, and psychogenic pathways as well as the effects of drugs and others factors play important roles in the development of ED and recent studies suggest that ED as a result of sleep apnea might involve the nitric oxide synthase and phosphodiesterase- mediated pathways targeted by tadalafil and other similar products.
Going forward, it’s theorized that the treatment of SDB might also aid in the reversal of erectile dysfunction.
More recent studies conclude “a 95% confidence interval of 0.18–0.71, indicating that in patients without OSA (obstructive sleep apnea), the risk of ED is significantly lower compared with patients with OSA. The available evidence shows that OSA is associated with a higher risk of ED”.*
