Objectives: the study aims to assess the relationship between obesity and prostatic markers (total prostatic specific antigen (tPSA), and free prostatic specific antigen (fPSA)). Methods: this study was conducted on 127 men aged ≥40 years at The Department of Urology at Al-Ramadi Teaching Hospital. Exclusion criteria were a history of previously diagnosed or treated prostate cancer, the use of prostacare or any drugs that affect the levels of PSA in the serum. Results: the age range of the participants of the study was between 40–80 year. The number of men with normal BMI was 26 (20.47%), 47 men were overweight (37%), 33 men were obese (25.98%), and finally, 21 men were severely obese (16.53%). The mean of parameters total and free prostate-specific antigen (tPSA, fPSA), in the study, were (mean ± SD) (1.683±0.563) ng/ml, (0.537±0.189) ng/ml, respectively. Conclusions: there are no significant relationships between BMI, tPSA, and fPSA, at P≤0.05 in a sample of Iraqi men.
