PURPOSE: We evaluated the correlation of prostate specific antigen (PSA) and ejaculation in patients with symptomatic benign prostatic hyperplasia and an active sexual life. MATERIALS AND METHODS: In a study of 40 patients 50 to 60 years old (mean age 55) with prostatic symptoms serum PSA was evaluated before as well as 1 and 7 days after ejaculation. Due to clinical significance of PSA in diagnosis and monitoring of prostate cancer, we included men at risk age and with an active sex life. RESULTS: The results were compared to those of a control group of 10 asymptomatic (without coitus) men 50 to 60 years old (mean age 55 years). There were no statistically significant differences in PSA levels before and after ejaculation or between the groups. These results suggested that there was no physiological relationship between ejaculation and PSA level. CONCLUSIONS: Based on our data we conclude that sexual activity does not preclude the use of PSA to screen men for prostatic cancer.
