Abstract:
:Activities of deoxyribonucleic acid (DNA) polymerase alpha, beta, and gamma were measured in extracts of testicular biopsy specimen obtained from 37 cases of male infertility with left varicocele and compared with those of 6 normal controls. It was observed that levels of DNA polymerase alpha, beta, and gamma were significantly lower in infertile men than normal controls on both sides of testes. Among three DNA polymerases, the level of DNA polymerase beta activity well correlated with the histological findings (Johnsen's score), i.e., the extent of differentiation of germinal cells. DNA polymerase beta activity appeared to be the lowest in the patients whose sperm density was less than 5 X 10(6)/ml. On the other hand, no correlation was apparent between levels of DNA polymerases and other clinical parameters, e.g., testicular volume, sperm motility, grade of varicocele, and serum hormone levels. These results suggest that the combined decrease in the DNA polymerase activities may be one of the factors that have deleterious effects on spermatogenesis in varicocele patients.
