Traumatic masturbation and erectile dysfunction: A matched case–control study

Abstract

ObjectiveTo identify atypical masturbatory behaviors (AMB) and to reveal their effects on both sexual and masturbational erection hardness in men with erectile dysfunction (ED).MethodsPatients with ED and healthy controls were questioned about their masturbation habits. Accordingly, “rubbing in a prone position,” “pressure on penis,” and “masturbation through clothes” were included in the traumatic masturbation syndrome (TMS) group. Erection hardness score (EHS) is used to measure the erectile functions during masturbation (mast), foreplay (presex), and sexual intercourse (sex), separately.ResultsThe data of 448 participants, 266 (59%) from the patient group, and 182 (41%) from the control group were analyzed. The mean ages were 30 years in both groups (p = 0.734). The rate of “rubbing in a prone position” and “penile pressure” while masturbating was higher in patients than the controls (10.2% vs. 6%, p = 0.024 and 8.6% vs. 3.3%, p = 0.0002, respectively). Patients had 2.2‐fold (odds ratio, 2.21; 95% confidence interval, 1.40–3.47; p = 0.001) increased risks of having at least one AMB, compared with controls. In the secondary analysis, the patient group was divided into 2 subgroups according to having TMS (ED + TMS) or not (ED). The percentage of patients with EHS≥3 during masturbation was higher than those during sex and presex in the “ED + TMS” group (60.2%, 38.8%, and 37.2%, respectively, p = 0.0001; n = 98). Comparing the percentage of patients with EHS≥3 during mast, presex, and, sex was found to be similar in the “ED” group (58.9%, 56.5%, and 56%, respectively, p = 0.753; n = 168).ConclusionAtypical masturbatory behaviors are more common in young men presenting with erectile dysfunction. These patients have higher erection hardness scores during masturbation compared to partnered sex.
