目的：探测睾丸淋巴管阻断后，睾丸重量变化与曲细精管直径变化的相关关系。方法：用外科手术的方法将２５只正常成年ＳＤ大鼠双侧睾丸淋巴管阻断后，观察术后２、６、１２、２４和４８ｄ睾丸重量的变化，并用自动图像分析仪测曲细精管直径，进行相关回归分析。结果：睾丸重量与曲细精管直径呈正相关关系（ｒ＝０．９０７４）。睾丸重量越小，曲细精管直径越小。结论：睾丸淋巴管阻断的大鼠，曲细精管直径可由睾丸重量来预测，反之亦然。
Objective: To detect the relationship between testicular weight change and seminiferous tubule diameter change after testicular lymphatic obstruction. Methods: Twenty-five normal adult Sprague-Dawley rats were occluded with bilateral testicular lymphatic vessels. The testes weights at 2, 6, 12, 24 and 48 days after operation were observed. Tube diameter, correlation analysis. Results: There was a positive correlation between testicular weight and seminiferous tubule diameter (r = 0.9074). The smaller the testicular weight, the smaller the seminiferous tubule diameter. CONCLUSIONS: Rats with lymphatic testis and testes diameter can be predicted by testicular weight, and vice versa.
