The Impact of Obstructive Sleep Apnea in Erectile Dysfunction

April 5, 2019 updated by: Ferran Barbe, Sociedad Española de Neumología y Cirugía Torácica

The syndrome of obstructive sleep apnea (OSA) is a common condition that affects 2-4% of the general population, causing an increase in sympathetic activity, changes in systemic blood pressure, and is associated with cardiovascular disease. The pathophysiological mechanisms that are altered as a result of the events associated with obstructive sleep apnea (hypoxia-reoxygenation, arousals and sleep fragmentation), are associated with an increased risk of developing erectile dysfunction in patients with Obstructive Sleep Apnea. Until today, the studies linking Erectile Dysfunction with Obstructive Sleep Apnea (OSA) are epidemiological studies.

The alterations in the expression profile of endothelial and cardiovascular dysfunction biomarkers and sex hormones disorders that are altered as a result of the events associated with OSA are associated to erectile dysfunction development.

Treatment with continuous positive airway pressure (CPAP) reverses the effects of OSA and patients with erectile dysfunction may improve erectile function.

The primary objective of the study is:

1. To evaluate the impact of CPAP treatment on erectile dysfunction in OSA patients.

The secondary objectives are:

  1. To determine the profile of synthesis of different biomarkers related to endothelial dysfunction and cardiovascular disorder, which are altered as a result of the syndrome of obstructive sleep apnea and its relation to the risk of developing erectile dysfunction.
  2. To compare the secretion profile of sex hormones related to control erectile function in a group of patients with syndrome of obstructive sleep apnea with and without erectile dysfunction.
  3. To assess the prevalence of erectile dysfunction in patients with OSA.
  4. To compare the psychological profile of patients with OSA with and without erectile dysfunction in order to detect psychological distress associated with the risk of developing erectile dysfunction.
  5. To evaluate the impact of CPAP treatment on the secretion profile of sex hormones related to control erectile function in OSA patients.
  6. To evaluate the impact of CPAP treatment on the psychological profile of patients with erectile disfunction in OSA patients.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in International Index Erectile Function (IIEF) score
Time Frame: At baseline and 3 month
Effect of 3-months CPAP treatment on the changes in the International Index Erectile Function score of patients with Erectile Dysfunction.
At baseline and 3 month

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Self-Esteem And Relationship (SEAR) score
Time Frame: At baseline and 3 month
Compare the psychological profile of patients with OSA with and without erectile dysfunction in order to detect psychological distress associated with the risk of developing erectile dysfunction, using SEAR score. Evaluate the impact of CPAP treatment on the change in SEAR score after 3 months.
At baseline and 3 month
Changes in Sexual hormone profile (Testosterone, SHBG, free Testosterone, Prolactin, LH, and FSH)
Time Frame: At baseline and 3 month
Compare the secretion profile of sex hormones related to control erectile function in a group of patients with syndrome of obstructive sleep apnea with and without erectile dysfunction. Evaluate the impact of CPAP treatment on the change in the sexual hormone profile after 3 months. All hormones measured in blood samples by means of Radioimmunoassay.
At baseline and 3 month
Changes in Endothelial dysfunction biomarkers (ADMA, ICAM-1, VCAM-1, and VEGF)
Time Frame: At baseline and 3 month
Determine the profile of synthesis of different biomarkers related to endothelial dysfunction and cardiovascular disorder associated to obstructive sleep apnea and its relation to the risk of developing erectile dysfunction. Evaluate the impact of CPAP treatment on the changes in endothelial dysfunction biomarkers after 3 months. All markers measured in blood samples by means of Radioimmunoassay.
At baseline and 3 month
