【摘要】 目的：验证过滤型络合铜纳米高分子复合材料输精管节育器(IVD)对雄犬的节育作用。方法：选雄性成年Beagle犬6只,手术植入IVD,术后1个月、3个月、6个月和12个月各采集犬精液,分别检测精子密度、精子活动力和精浆α-糖苷酶,并以仅做假手术的对照组(2只)作对照。结果：手术植入IVD后,雄犬精液中精子含量显著下降,3个月后精液中没有检测到活精子。结论：植入过滤型络合铜纳米高分子复合材料IVD可显著降低雄犬精液中精子的密度和活动力,是一种值得进一步研究的非阻塞性IVD。更多还原

【Abstract】 Objective:To proof the comtra ceptive effect of the filtering nano-copper complex/polymer composites intravas device (IVD) in dogs.Methods:Eight male adult beagel dogs were collected,6 of them were planted with IVD in their vas deferens and 2 as the control.Their semen were collected to test sperm densities, sperm activities in 1 month,3 months,6 months and 12 months after the operation.Results:The densities of sperms were reduced significantly after the IVD was implanted,no viable sperms were found in the 3rd month. Conclusion:The filtering nano-copper complex/polymer composites IVD can reduce the densities of dog’s sperms significantly.更多还原
