Introduction: Most epidemiological studies suggest that premature ejaculation (PE), also referred to as early ejaculation and rapid ejaculation, may be the most common male sexual disorder. The exact etiology of PE is unknown. Psychological/behavioristic and biogenic etiologies have been proposed. Objective: Initial reports indicate that there are hormone differences between men with primary (lifelong) and secondary (acquired) PE. This study was designed to investigate hormone profiles of these two subgroups. Methods: Men who presented to our outpatient clinic with PE were enrolled in this study. The diagnosis and classification (primary or secondary) of PE was based on patient medical and sexual history according to guidelines of international society of sexual medicine (ISSM) and European association of urology (EAU). Complete physical examination was done and we measured thyroid stimulating hormone (TSH), testosterone (T), and prolactin (P) for all patients. Statistical analyses included descriptive statistics and independent-measures t-test for univariate analyses. Analysis of covariance was used for multivariable analyses. Results: 506 men were included in this analysis. The average age of these men was 44±12 years old and the mean body mass index (BMI) was 26.7±5.5. The mean levels of T, TSH, and P for the entire sample was 4.38±1.69, 2.31±3.56, and 10.56±11.04, respectively. There were 267 men in the primary PE group and 239 men in the secondary PE group. The men with primary PE were significantly younger than those with secondary PE (37±11 vs. 52±12, p=0.001). There were no significant differences in BMI between the groups. On univariate analyses, there was no differences between the primary PE and secondary PE groups in T (4.39±1.66 vs. 4.38±1.84, p=0.94), TSH (2.31±4.89 vs. 2.20±2.07, p=0.76), and P (10.65±8.13 vs. 10.46±13.46, p=0.86). When controlling for age in multivariable analyses, there continued to be no differences between the two groups (p values ranging from p=0.56 to 0.81). Conclusions: hormonal profile including T, TSH and P seem to be in the normal range in men with PE and there is no statistical difference in these hormones between primary and secondary PE Disclosure: No. [ABSTRACT FROM AUTHOR]
