title: [Comparative study of determined biochemical parameters in semen of vasectomized and non-vasectomized subjects].
abstract: OBJECTIVE
  Biochemical parameters, fundamentally those of prostatic origin, were analyzed and compared to determine the semen composition of vasectomized and non-vasectomized subjects.
  
  
  METHODS
  100 ml of semen from each group (vasectomized and non-vasectomized) were obtained. After thawing, the pool was homogenized and 5 one-ml sample from each one were analyzed for the following biochemical parameters: gamma glutamyl transferase (GGT), lactic dehydrogenase (LDH), prostate acid phosphatase (PAP), prostate-specific antigen (PSA) and total protein (TP) in the seminal plasma. Determination of the foregoing biochemical parameters was performed automatically with autoanalyzers.
  
  
  RESULTS
  The mean values for the vasectomized and non-vasectomized groups were respectively: a) GGT: 8890 +/- 811 and 5714 +/- 403 IU/L; b) LDH: 7045 +/- 879 and 2465 +/- 339 IU/L; c) PAP: 2,099,000 +/- 330,764 and 1,860,000 +/- 302,138 ng/ml; d) PSA: 953,000 +/- 154,715 and 1,018,000 +/- 119,685 ng/ml; total protein: 39,860 +/- 1094 and 37,900 +/- 5606 micrograms/ml.
  
  
  CONCLUSIONS
  Analysis of the different biochemical parameters showed no statistically significant differences between the mean values for PAP, PSA and total protein for the vasectomized and non-vasectomized group, but statistically significant differences were found for GGT and LDH (p < 0.001).
