The relationship between obstructive sleep apnoea and erectile dysfunction: An underdiagnosed link? A prospective...

Area of Science:

• Urology
• Sleep Medicine
• Andrology

Background:

• Obstructive sleep apnea (OSA) is a prevalent condition affecting many men.
• Erectile dysfunction (ED) is a common comorbidity with significant impact on quality of life.
• The relationship between OSA and ED requires further investigation into clinical characteristics and risk factors.

Purpose of the Study:

• To determine the prevalence of erectile dysfunction (ED) in male patients with suspected obstructive sleep apnea (OSA).
• To identify clinical characteristics and independent predictors associated with ED in this patient group.

Main Methods:

• A cross-sectional study involving 133 male patients with suspected obstructive sleep apnea (OSA).
• Assessment included clinical evaluations, laboratory tests, BMI, Epworth Sleepiness Scale (ESS), 5-International Index of Erectile Function (IIEF), overnight ambulatory polygraphy, and drug-induced sleep endoscopy (DISE).
• Statistical analyses were performed to identify correlations and independent predictors of ED.

Main Results:

• Of 80 patients diagnosed with OSA, 60% reported erectile dysfunction (ED).
• Significant correlations were found between IIEF scores and age, hypertension, diabetes, ESS, apnea-hypopnea index (AHI), oxygen saturation nadir, and oxygen desaturation index (ODI).
• Age, diabetes, and oxygen saturation nadir were identified as independent predictors of ED. Higher ESS, AHI, oxygen saturation nadir, ODI, and albumin levels were observed in patients with ED compared to those without.

Conclusions:

• Patients with obstructive sleep apnea (OSA) face a significantly elevated risk of developing erectile dysfunction (ED).
• Routine screening for erectile dysfunction is recommended for males diagnosed with obstructive sleep apnea (OSA) to address associated risk factors.
• No significant association was found between drug-induced sleep endoscopy patterns and erectile dysfunction in this cohort.
