| 摘 要： | In the present study,male SD rats were used to evaluate the efficacy of a new vas occlusion device,intravas device(IVD) and long-term morphological change of both vas and IVD.After inserting IVD into bilateral vas,all rats(9)became sterilized as proved by mate test and the fact that no sperm was found in female vagina after mat-ing.Half a year later,there had been a large amount of sperm in vas lumen dilated and sperm granuloma was found in the proximal end of IVD.Scanning electron microscope studies showed that nylon threads in IVD were covered by protein like matter.There were some normal sperms between the nylon sutures.A few sperms with deformed structure were found in the distal end of IVD.Conclusion:our studies showed that IVD could be an effective device in SD rats.Fluid and some deformed sperms may pass through IVD,but these sperms have no fertility.The mechanism of IVD needs to be further investigated.
