Is it only a sleeping disorder or more? Restless legs syndrome and erectile function

Abstract

Objective: Sexual dysfunction and restless legs syndrome (RLS) have similar pathophysiological properties. This study evaluated the presence of erectile dysfunction (ED) and premature ejaculation (PE) in patients with RLS.

Materials and methods: Fifty patients in the RLS group and 50 in the control group were included in the study. The International Restless Legs Syndrome Study Group rating scale, the five-item International Index of Erectile Function and the Premature Ejaculation Diagnostic Tool were used to define the RLS and erectile function of both the study and control groups. A stopwatch technique was used to evaluate the intravaginal ejaculatory latency time of patients in the study.

Results: The mean age of patients in the RLS and control groups was 53.5 ± 9.9 and 53.2 ± 8.8 years, respectively (p = 0.527). None of the patients in either group had diabetes mellitus. There was no difference between the groups in terms of history of hypertension, body mass index and total testosterone level. There were 27 patients (54%) in the RLS group and 17 patients (34%) in the control group with PE (p = 0.008). There were 26 patients (52%) with ED in the RLS group and 17 (34%) in the control group (p = 0.069). The prevalence of moderate and severe ED was significantly higher in the RLS group (p = 0.045).

Conclusions: PE was more prevalent in RLS than in control patients. On the other hand, the rate of ED did not differ between the groups. In addition to receiving a neurological evaluation, RLS patients must be evaluated for sexual function.
