title: Seminal plasma prostate-specific antigen level in benign prostatic hyperplasia.
abstract: BACKGROUND
  We evaluated the role of the seminal plasma PSA level in the prediction of the response to alpha-blocker treatment in patients with benign prostatic hyperplasia.
  
  
  METHODS
  18 male patients with lower urinary tract symptoms were enrolled in the study. After their blood was sampled for PSA, ejaculates of all the subjects were obtained. Serum and seminal plasma PSA levels were calculated by Active PSA IRMA kit. Patients were given 4 mg/day doxazosin for a period of 6 weeks, following which their International Prostate Symptom Score (IPSS) evaluation was repeated. The correlation between serum PSA, seminal plasma PSA and PSA density levels and the percentage improvement in IPSS was investigated.
  
  
  RESULTS
  The mean serum PSA level, the mean PSA density and the mean seminal PSA level of the patients were 2.7 +/- 1.2 ng/ml, 0.05 +/- 0.02 ng/ml/cm(3) and 0.7 +/- 0.39 g/l, respectively. The percentage improvement in IPSS varied from 26.9 to 53.5%. Serum PSA and serum PSA density were not useful in the prediction of the response to alpha-blocker treatment, but the seminal PSA levels correlated with the percentage improvement in the IPSS (p = 0.017).
  
  
  CONCLUSIONS
  Seminal plasma PSA has been found to be a better predictor of the response to alpha-blocker treatment when compared to serum PSA and PSA density.
