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).
