| 摘 要： | 目的了解经腹股沟管的兔输精管结扎术后附睾内的精子郁积情况。方法6月龄正常雄性日本大耳白兔18只,经腹股沟管进行单侧闭合性(11只动物)和开放性(7只动物)输精管结扎,术后3月取双侧附睾,制作甲基丙烯酸树脂包埋切片,用体视学方法定量研究附睾内郁积的精子团的体积。结果两种结扎术后结扎侧附睾的总体积均显著增加(与对侧假手术侧相比),分别增加了59%(闭合性结扎)、44%(开放性结扎);附睾内精子团的总体积显著增加了148%(闭合性结扎)、120%(开放性结扎)。结扎侧附睾的肿胀以及附睾内精子的郁积主要在附睾的尾部,附睾头部及体部的肿胀及其内的精子郁积并不明显。结论远离附睾尾的兔输精管结扎术后3月,睾丸仍在产生大量精子,附睾内精子大量郁积。

| Abstract: | Objective To study the stasis of spermatozoa in the epididymis after vasectomy via inguinal canal in rabbits.Methods 18 normal male Japanese white rabbits(aged 6 months) were subjected to unilateral close-ended(11 animals) or open-ended(7 animals) vasectomy via the inguinal canal.Three months after operation,epididymides were removed and methacrylate resin-embedded sections prepared.The volume of spermatozoal mass filled up in the epididymis was quantitatively studied using stereological methods.Results The... |
