Association of diet with prostate specific antigen and prostate volume.

Background: Prostate is an important male reproductive system gland and its disorders can affect men's quality of life and health. Prostatitis, benign prostatic hyperplasia (BPH), and prostate adenocarcinoma are major disorders that can be found in all men in different ages.

Objectives: The aim of this study was to investigate the association of diet with serum prostate specific antigen (PSA) level as well as prostate volume.

Age specific reference levels of serum prostate-specific antigen, prostate volume and prostate specific antigen density in healthy Iranian men.

Background: It is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum PSA in Iranian population.

Objective: To determine age-specific reference ranges for serum prostate-specific antigen (PSA) concentration and PSA density (PSAD) and prostate volumes in a population of healthy Iranian men.

Methods: Nine-hundred and thirteen healthy Iranian men, aged 50-79 years, underwent a detailed clinical evaluation including a digital rectal examination, a serum PSA determination (DRE) and transrectal ultrasound (TRUS).
