An unresolved discussion: presence of premature ejaculation and erectile dysfunction in lumbar disc hernia

Premature ejaculation (PE) and erectile dysfunction (ED) are both frequent diseases with several questions about the aetiological factors for these disorders. Lumbar disc herniation (LDH), which can cause both neurological and physiological impairments, may be a causative reason. We prospectively tried to evaluate the presence of PE and ED in patients with LDH and identify the effect of both surgical and physical therapy treatments for LDH on PE and ED. A total of 50 patients with LDH and a corresponding control group without LDH at an age of 18-50 years were included in the study. Both PE and ED were evaluated with premature ejaculation diagnostic tool (PEDT) and International Index of Erectile Function. Mean intravaginal ejaculatory latency time (IELT) was calculated at their 5 consecutive intercourse. Physical therapy or microdiscectomy was performed according to indication. After 6 months of follow-up, patients in treatment group were re-evaluated for PE and ED. Mean age of study and control group was 34.1 +/- A 3.3 and 34.2 +/- A 4.0 years, respectively (p = 0.979). In LDH group, IELT was < 1 min in 12 (24 %), 1-2 (16 %) min in 8, 2-3 min in 7 (14 %), 3-4 min in 7 (14 %) and 4 or more minutes in 16 (32 %) patients. These numbers were 11 (22 %), 8 (16 %), 5 (10 %), 9 (18 %) and 17 (34 %) in control group, respectively. Mean PEDT score of patients who had IELT < 1 min was 11.9 +/- A 2.1 and 10.7 +/- A 2.1 in study and control group, whereas it decreased to 1.0 +/- A 2.8 and 0.5 +/- A 1.8 as IELT increased over 4 min, respectively. There were 11 (22 %) patients with ED in LDH group, whereas there were only 2 (4 %) in control group (p = 0.017). Twenty patients with LDH underwent surgery while 30 had been taken into physical therapy. After 6 months, patients with PE significantly decreased in both surgery and physical therapy group (p = 0.025 and p = 0.046). Patients with ED also decreased after treatment, but the numbers were so limited for statistical evaluation. Although ED was more frequent in patients with LDH, PE was similar in both study and control groups, but the treatment of LDH had positive effects on PE and ED
