摘　　要：隐睾是动物最常见的睾丸发育不良症状之一,严重影响着生理健康及繁育能力。该试验以猫单侧隐睾为研究对象,通过HE染色形态学观察、组织学数据测量。结果显示,隐睾与正常睾丸HE染色相比,单侧隐睾间质细胞较多且聚集,曲精小管内生精细胞较少、分布散乱,部分聚集在曲精小管中央呈岛屿样结构。测量数据证实隐睾曲精小管数量平均为7.45个/mm^(2),显著多于正常睾丸的5.38个/mm^(2)(P<0.01);但隐睾曲精小管直径平均为27.79μm,明显小于正常睾丸33.57μm,曲精小管数量和直径均成极显著性差异(P<0.01)。单侧隐睾与正常睾丸在组织形态学结构存在明显的差异,曲精小管数量较多而直径较小,可能是导致隐睾症公猫繁殖能力弱的重要因素。Cryptic testicle is one of the most common symptoms of testicular dysplasia in animals.The experiment was carried out by HE staining morphology and histological data.The results showed that compared with the normal HE staining of the testicles,the one-sided cryptostricular mesenchymal cells are more and more clustered,the intracellular spermatocytes are less and dispersed,partly clustered in the central tricellular island-like structure.The measurements showed that the number of cryptostracic tubes averaged 7.45/mm^(2),significantly more than 5.38/mm^(2)(P<0.01)of normal testicles.However,the diameter of the cryptostracoid tubes averages 27.79μm,which is significantly less than that of the normal testicles 33.57μm and the number and diameter of the tubes are significantly different(P<0.01).There are obvious differences in histomorphological structure between the one-sided cryptorchidium and the normal testicle.The number of curvature tubes is large and the diameter is small.
