ABSTRACT
Prostate specific antigen (PSA) is a specific marker of prostate tumor which is used for diagnosis of prostate cancer. Apart from prostate cancer,different factors may affect PSA level and ejaculation is one of these possible factors .In a study on 21 patients at ages of 18-37, serum levels of PSA were measured before the ejaculation and about two hours after it. There was no statistically significant difference between the PSA levels before and after ejaculation. Based on this study ,PSA levels can be measured within a short interval of ejaculation without any fear about the false increase or decrease in its serum levels.
