【Author】 LING Xiao-Yang, et al Jilin Research Institute for Family Planning, Changchun. Although the function of spermatogenesis of the testis could recover after vaso- vasostomy, spermacrasia and lack of fertilizasion ability of the sperm happened in some cases.In this study, an animal model of vasovasostomy with Japanese white rabbit was established and the sperm plasma membrane bound adenosine deaminase (ADA)activity was analyzed.The result showed that the ADA activity (186.87±63.73 nMols/mg Pro/h for non-pregnant group, 132.81±49.85 nMols/mg Pro/h for pregnant group) was significantly higher than that of control (81.22±47.63 nMols/mg Po/h) (P<0.01).Also a significant difference of the ADA activity between non-pregnant group and pregnant group was observed (P<0.01). These results were consistent with our previous investigation and we concluded that ADA is invloved in the process of sperm maturation.
