The aim of this study was to determine whether testicular volume can serve to predict patterns of spermatogenesis in azoospermia. In 27 tests of azoospermic infertile men, cytological specimens from several sites from each testis were obtained by fine needle aspiration. Testes were classified according to the most mature spermatogenic cell type. Classifications were testes with spermatozoa, with arrested spermatogenic development, and with only Sertoli cells. Prior to fine needle aspiration the 3 dimensions of each testis were determined ultrasonically and its volume calculated. Mean testicular volume (+/- SD) was 7.71 (+/- 5.95) ml for testes with spermatozoa and 7.55 (+/- 2.35) and 7.31 (+/- 4.42) ml for testes with spermatogenic maturation arrest and with only Sertoli cells, respectively (differences not significant). It is concluded that testicular volume can not be used as a predictive parameter, neither for the presence of spermatozoa nor for the cytological pattern of the testes of azoospermic infertile men.
本研究的目的是确定睾丸体积是否可用于预测无精子症患者的精子发生模式。对27例无精子症不育男性进行检测，通过细针穿刺从每个睾丸的多个部位获取细胞学标本。根据最成熟的生精细胞类型对睾丸进行分类。分类包括有精子的睾丸、生精发育停滞的睾丸和仅有支持细胞的睾丸。在细针穿刺前，通过超声测定每个睾丸的三维尺寸并计算其体积。有精子的睾丸平均体积（±标准差）为7.71（±5.95）ml，生精成熟停滞的睾丸和仅有支持细胞的睾丸平均体积分别为7.55（±2.35）ml和7.31（±4.42）ml（差异不显著）。得出的结论是，睾丸体积不能作为预测参数，无论是对于无精子症不育男性睾丸中精子的存在情况，还是对于其睾丸的细胞学模式。
