我们在输精管内节育器研究[生殖与避孕,1992,12(4):76]的基础上,进行了输精管内硅橡胶空芯铜节育器的研究,报告如下。一、材料与方法将内径0.2、0.4、0.6、0.8、1.0、1.2、1.4mm,外径0.4、0.6、0.8、1.0、1.2、1.4、1.6mm 的空芯铜管切成6mm 一段,将同等内径的硅橡胶管套在铜管上,两端各长出1mm,再斜形剪去硅橡胶管。选精子数20×10~8/ml 以上的本地山羊21只,随机分为7组,每组3只。显露输精管,根据节育器大小用不同型号的输精管
We conducted a study on vas deferens silicone rubber hollow copper IUDs based on the study of the vas deferens IUD [Reproductive and Contraception, 1992, 12 (4): 76] and the report is as follows. First, the material and method The inner diameter of 0.2,0.4,0.6,0.8,1.0,1.2,1.4mm, outer diameter 0.4,0.6,0.8,1.0,1.2,1.4,1.6 mm hollow copper tube cut into 6mm section, will be the same The inner diameter of the silicone rubber tube in the copper tube, the ends of each grow 1mm, then cut the silicone rubber tube oblique. Twenty-one domestic goats with sperm count of 20 × 10 ~ 8 / ml were randomly divided into 7 groups with 3 in each group. Vas deferens are revealed, with different types of vas deferens depending on the size of the IUD
