Worsening obstructive sleep apnea (OSA) is associated with declining erectile function, according to a systematic review and meta-analysis published in the International Journal of Impotence Research.
Researchers analysed eight observational studies to evaluate the relationship between OSA severity and erectile dysfunction (ED) using validated measures. Seven studies involving 594 participants assessed whether the apnea-hypopnea index (AHI) correlated with erectile function. Six of these found that increasing AHI was associated with lower scores on the International Index of Erectile Function (IIEF), indicating worsening erectile function as sleep apnea became more severe.
The pooled analysis showed a statistically significant moderate negative correlation between AHI and erectile function. Additionally, three studies involving 513 participants found that higher minimum oxygen saturation during sleep was associated with better erectile function, suggesting that greater oxygen deprivation correlates with poorer outcomes.
ED prevalence among men with OSA ranged from 59.3% to 69.0% across four studies, significantly higher than in groups without OSA. Age was consistently identified as a significant factor in both OSA severity and ED prevalence.ED prevalence among men with OSA ranged from 59.3% to 69.0% across four studies, significantly higher than in groups without OSA.

Three studies evaluated continuous positive airway pressure (CPAP) therapy, with one showing ED completely resolved in 42.6% of patients after treatment. Another demonstrated significant improvement in erectile function scores after three months of therapy. However, researchers noted these treatment results should be interpreted cautiously given the limited number of studies with relatively short follow-up periods.
Up to one billion people worldwide may be affected by OSA, which shares common biological pathways with ED, including intermittent hypoxia, vascular dysfunction, inflammation, and reduced nitric oxide availability. The findings emphasise the importance of considering OSA screening in men presenting with ED, particularly when symptoms of sleep-disordered breathing are present.
