ABSTRACT

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)
