目的　探讨超声引导下细针抽吸睾丸组织的诊断价值。  方法　回顾分析2015年1月到2016年12月的睾丸细、粗针穿刺活检病理切片，比较其中生精小管断面数量的差异；除生精小管以外的其他成分（皮肤、血管及纤维软组织）及血肿的差异。   结果　粗针穿刺与细针抽吸睾丸组织病理切片，生精小管断面数量大于20的，粗针穿刺组有8例(8/24,33.3%)，细针抽吸组有11例(11/20,55.0%)，组间对比（χ2=2.087，P=0.149），两者差异无统计学意义；存在其他成分例数，粗针穿刺组有19例( 19/24，79.2%)；细针抽吸组有1例(1/20，0.9%)，组间对比(χ2 =24.203，P=0.000)，两者差异有统计学意义；穿刺后出现血肿例数，粗针穿刺组有5例(5/24，20.8%)，而细针抽吸组20例均未见血肿，组间对比（χ2=4.70，P=0.032），两者差异有统计学意义。  结论　细针抽吸睾丸组织标本满意，几乎无其他成分干扰，具有较大的临床应用价值。

Objective　To evaluate the diagnostic value of ultrasonography guided fine needle aspiration for testis tissue.  Methods  The tissue slices of the testis through fine needle aspiration and core needle biopsy were collected from January 2015 to December 2016, the difference in the number of microtubules was compared. In addition, the differences in other ingredients (skin, blood vessels and fibrosoft tissue) and hematoma were analyzed.　Results　The testicle histopathological sections collected by core needle puncture or fine needle aspiration presented more than 20 seminiferous tubule sections for 8 patients in the core needle group and 11 patients in the fine needle group , without statistically significant difference between the two groups （χ2=2.087，P=0.149）; additional components were present in the sections for 19 patients in the core needle group and 1 patient in the fine needle group, with statistically significant difference between the two groups(χ2 =24.203，P=0.000); 5 patients in the core needle group and 0 patient in the fine needle group experienced post-puncture hematoma, with statistically significant difference between the two groups（χ2=4.70，P=0.032）.　Conclusion　The fine needle aspiration of testicular tissue is satisfactory, and almost no other components interfere with it, and have great clinical application value.
