Impaired Human Sexual and Erectile Function Affecting Semen Quality, in Obstructive Sleep Apnea: A Pilot Study

Area of Science:

• Urology
• Sleep Medicine
• Andrology

Background:

• Obstructive sleep apnea (OSA) is a prevalent condition with significant public health implications.
• Emerging research suggests a connection between OSA and diminished male reproductive health.
• The impact of OSA on sexual function and semen parameters requires further investigation.

Purpose of the Study:

• To examine the association between OSA and male sexual function, erectile function, and semen quality.
• To evaluate the therapeutic effect of continuous positive airway pressure (CPAP) on these parameters in OSA patients.

Main Methods:

• A study involving 41 male subjects undergoing polysomnography for suspected OSA.
• Assessment of erectile and sexual function using the International Index of Erectile Function (IIEF-15) questionnaire.
• Semen analysis and testosterone level measurements were conducted, with a one-year follow-up for OSA patients on CPAP therapy.

Main Results:

• OSA patients exhibited significantly impaired erectile function, lower testosterone levels, and reduced semen quality compared to controls.
• Body Mass Index (BMI) and IIEF scores were identified as independent determinants of the Apnea-Hypopnea Index (AHI).
• One year of CPAP treatment led to a notable improvement in sexual function among OSA patients.

Conclusions:

• This study reinforces the link between OSA and impaired erectile function and compromised semen quality.
• Consistent adherence to CPAP treatment demonstrates a positive impact on erectile function in men with OSA.
