Abstract
Background
To examine the effects of type 2 diabetes mellitus (DM) on the variables associated with prostatic growth including serum prostate-specific antigen (PSA), serum testosterone, and prostate volume, and to correlate these variables with the duration of diabetes treatment.
Methods
Our study was conducted over 3 months recruiting 501 men aged ≥ 55 years; of whom 207 had type 2 DM. Exclusion criteria were active urinary tract infection, suspicious rectal examination, urologic cancer, end-organ damage, and recent urological manipulations. Serum PSA and serum testosterone were measured. Prostate volume was determined by abdominal ultrasonography using an ellipsoid formula.
Results
The mean patient age was 60.21 ± 5.95 years. The mean PSA, testosterone, and prostate volume for diabetic men were 2.3 ng/mL, 3 ng/mL, and 56 g, respectively. The corresponding values for nondiabetic men were 3.5 ng/mL, 4 ng/mL, and 51 g, respectively (P = 0.001, P = 0.001, P = 0.03, respectively). The mean PSA density was 0.049 ± 0.043 ng/mL/cm3 in diabetics versus 0.080 ± 0.056 ng/mL/cm3 in non-diabetics (P < 0.001).
Conclusion
Type 2 DM is significantly associated with lower serum PSA and testosterone, and larger prostate volume.
