The prevalence of premature ejaculation in young Turkish men

This study was conducted to investigate the prevalence of premature ejaculation (PE) in young Turkish men and to evaluate PE in a population having good physical and mental health. A total of 1230 healthy university graduates aged between 24 and 30 attending the police academy having no physical or mental problems were included in the study. To identify the presence of PE, the participants were asked to complete the premature ejaculation diagnostic tool (PEDT). The mean ages in the PE and non‐PE group were 27.3 and 26.7 respectively. There was no statistically significant difference between the two groups concerning age, body mass index (BMI), smoking status and alcohol consumption (P > 0.05). The PE prevalence was found to be 9.2%. The mean PEDT score was calculated as 6.3. Of the participants, 92 scored 11 and higher (9.2%), 66 scored 9 and 10 (6.6%), and the remaining 842 obtained a score equal to or lower than 8 (84.2%). The lower prevalence of PE in young Turkish men compared to the results of studies in the literature can be attributed to the physical and mental well‐being of the participants. This study showed that the prevalence of PE in young men with good physical and mental health is lower than that found in the literature.

Association between serum folic acid level and erectile dysfunction

This study measured the serum folic acid (FA) level in patients with erectile dysfunction (ED) and evaluated the possible association between the serum FA level and erectile function. The study divided 120 patients with ED into 3 groups of 40 patients each: those with severe, moderate and mild ED. Forty healthy men served as controls. Fasting serum samples were obtained, and the total testosterone, cholesterol and FA levels were measured using chemiluminescent immunoassays. There were no significant differences in the mean age, mean body mass index or mean serum total testosterone and cholesterol levels among the three ED groups and controls (P > 0.05). The mean serum FA concentrations were 7.2 ± 3.7, 7.1 ± 3.2, 10.2 ± 4.6 and 10.7 ± 4.6 ng ml−1 in the severe, moderate and mild ED and control groups respectively. The mean serum FA concentration was significantly higher in the control group than in the severe and moderate ED groups (both P < 0.001), but not the mild ED group (P = 0.95). Considering the significant differences in the serum FA levels between the control and ED groups, serum FA deficiency might reflect the severity of ED.

The Effect of Ejaculation Frequency on Serum Prostate-Specific Antigen Level

Objective: Serum prostate-specific antigen (PSA) levels are very important in the diagnosis of prostate cancer. Besides prostate cancer, PSA levels can also be increased by cystoscopy, prostate biopsy, prostatitis, and manipulation. There are also studies reporting that ejaculation affects serum PSA levels. In this study, we aimed to investigate the effects of ejaculation frequency on serum PSA level. Methods: A total of 135 male patients aged in the range of 48–69 years who presented with lower urinary tract symptoms at the urology outpatient clinic between October 2009 and August 2012 were included in the study. Three groups divided according to ejaculation frequency (Group 1, Group 2, and Group 3) were compared by total and free PSA (t/f PSA) values, age, International Prostate Symptom Score (IPSS), prostate volumes, and PSA density (PSAD). Results: There was no significant difference between t/f PSA values, age, IPSS, prostate volumes, and PSAD values of the groups. Conclusion: In our study, ejaculation frequency was found to have no effect on serum PSA levels. (JAREM 2015; 5: 56-9)
