本文观察了输精管结扎后1年内家兔睾丸、附睾体积和组织学变化。结果是对照组活体测量睾丸体积为3.36±0.54ml,尸检为1.39±1.59ml;术后3和6个月活体测睾丸体积分别为4.24±0.81ml和4.40±1.27ml,术后10个月处死组尸检体积为3.24±1.84ml,12个月为2.39±0.61ml,分别与对照组比较有显著差异(P(0.01);对照组尸检附睾尾体积为0.51±0.21ml,结扎10和12个月组分别为2.36±1.32ml和1.79±1.15ml,与对照组比较差异显著(P<0.01)。光镜下见曲细精管不同程度萎缩,炎细胞浸润,附睾管扩张,附睾精子肉芽肿只见于精索静脉结扎兔中,提示血管损伤是精子肉芽肿发生的重要因素之
In this paper, we observed the changes of testis and epididymis volume and histology in 1 year after vasectomy. The results showed that the testis volume in the control group was 3.36 ± 0.54 ml and the post-mortem was 1.39 ± 1.59 ml. The live testicular testicular volume was 4.24 ± 0.81 ml and 4.40 ± 1.27 ml respectively at 3 and 6 months after operation, and was sacrificed 10 months after the operation The volume of post-mortem examination was 3.24 ± 1.84ml, which was 2.39 ± 0.61ml at 12 months, which were significantly different from the control group (P <0.01). In the control group, the volume of post-mortem epididymal tail was 0.51 ± 0.21ml and the ligation time was 10 and 12 months (2.36 ± 1.32ml and 1.79 ± 1.15ml respectively), which were significantly different from those in the control group (P <0.01) .In the light microscope, the seminiferous tubules showed varying degrees of atrophy, inflammatory cell infiltration, dilatation of the epididymal tube, Seen in the varicocele ligation of rabbits, suggesting that vascular injury is an important factor in the occurrence of sperm granulomatosis
