摘　　要：采用组织学和形态学方法研究了中华白海豚(Sousa chinensis)的雄性生殖系统。以睾丸和附睾中是否存在精母细胞及精子细胞等作为判断雄性中华白海豚性成熟的标准,通过比较不同个体睾丸和附睾的组织结构特征,发现成熟个体的生精小管和附睾的组织学结构与未成熟个体间存在显著差异。通过测量样本睾丸的2个形态参数:生精小管直径和生精小管的相对面积,得到性成熟个体的生精小管直径为(118.3±12.8)μm,生精小管相对面积为0.52;未成熟个体的生精小管直径(47.4±3.5)～(60.3±6.0)μm,生精小管相对面积为0.27～0.40。The male genital system of Sousa chinensis was studied by histological and morphometric techniques. Sexual maturation was defined as the presence of spermatocyte sperm etc. in gonads. Evident difference was found in the histological structure of seminiferous tubules and epididymis between the immature males and mature males. Morphometric analysis showed that the diameter of semlnlferous tubules of mature dolphins was 118.3± 12. 8μm and the relative proportion of seminiferous tubules within the testis was 0.52. In immature males,the diameter of seminiferous tubules was between 47.4 ± 3.5 μm and 60.3 ± 6.0 μm, and the relative proportion of seminiferous tubules was between 0.27 and 0.40.
