Sleep and libido in men with obstructive sleep apnea syndrome

The objectives of this study were to investigate the relationship between a low libido and objective sleep parameters as well as mood disturbances in patients with obstructive sleep apnea syndrome (OSA).

We enrolled 436 untreated patients who were newly diagnosed with OSA (all male, mean age 42.8 years). Patients completed the Symptom checklist-90-Revised (SCL-90-R), Epworth Sleepiness Scale (ESS), Beck Depression Inventory-II (BDI), and Beck Anxiety Inventory (BAI). Patients were divided into low-libido and normal-libido groups according to their response to the statement "Loss of sexual interest or pleasure" on the SCL-90-R.

Approximately 23% of patients reported a low libido. Patients with a low libido were older (47.5 ± 9.0 vs. 41.4 ± 11.1 years; p < 0.001), had more nocturia (33.3% vs. 16.6%; p < 0.001), higher BDI (9.0 (5.0-14.0) vs. 5.0 (2.0-9.0); p < 0.001) and BAI score (11.0 (6.3-16.8) vs. 5.0 (2.0-10.0); p < 0.001). These patients had a lower non-REM sleep stage 3 (N3) % (0.1 (0-4.0) vs. 2.3 (0.1-7.9); p < 0.001). Multivariate analysis revealed that older age and higher BDI score were independent factors associated with a low libido.

Men with untreated OSA suffered from a low libido. Older age and depressed mood were the most important factors of low libido in middle-aged men with OSA.
