摘      要：Aim: To evaluate the sperm function after vasovasostomy. Methods: Semen samples from 42 subjects aftervasovasostomy (Group A: 1-6 months, Group B: 6-12 months; Group C: 12-18 months after vasectomy rever-sal) were investigated. Semen from 34 normal fertile men was used as controls. Sperm function tests, including hypo-osmotic swelling test (HOST), acridine orange (AO) fluorescence, acrosome reaction (triple-stain), cervical mucuspenetration test (CMPT), etc were done. Results: After vasectomy reversal, the percentage of HOST was signifi-cantly lower than that of the normal fertile men. In regard to AO, there were no significant differences between thethree vasovasostomy groups and between these 3 groups and the controls. With triple-stain, the percentage of normalacrosome reaction was significantly lower in Group A as compared with the controls, but not in Groups B and C. Therewere no significant differences in the results of CMPT between the vasovasostomy groups and the controls. However,the number of poor type was significantly higher in Groups A and C than in the controls; the percentage of nega-tive type were higher in Groups A and B than in the controls. Conclusion: After vasovasostomy a lower level ofHOST remained for one year and gradually recovered after one year. Six months after vasectomy reversal, the percent-age of acrosome reaction could be changed from lower level to normal range. The data of AO indicated that the geneticmaterial (double-stranded DNA) in spermatozoa was not affected by vasovasostomy. To evaluate the result of CMPTafter vasectomy reversal, not only the normal results but also the abnormal results ( poor and negative types)should also be ***: To evaluate the sperm function after vasovasostomy.
