The aim of this study was to determine the extent of sexual dysfunction in young male patients (18-24 years) with epilepsy. Forty-five male patients with epilepsy aged between 18 and 24, and forty-four age- matched healthy male volunteers were included in the study. Participants completed a battery of self-reported tests (ASEX: Arizona Sexual Experiences Scale, HADS: Hospital Anxiety and Depression Scale). Demographic and clinical variables were recorded. Serum total testosterone was measured between 8:00 and 10:00 a.m. in patients with epilepsy. Sexual function scores (sexual drive and penile erection) were higher in patients with epilepsy than those of the control group (p < 0.001 and p = 0.008, respectively). The difference between the mean total ASEX scores, which were 13.9 and 11.4 in patients with epilepsy and controls, respectively, was significant (p = 0.009). HAD anxiety scores were significantly higher in patients with epilepsy than controls (p = 0.01) (Table 2). HAD-depression scores of both groups were similar (p = 0.09). This study demonstrates that young male patients with epilepsy have lower levels of sexual activity and drive and more erectile problems. Impaired sexual function is associated with anxiety scores.
