An electron-microscopic study was performed to examine the shape abnormities of spermatozoon nuclei of drakes used for breeding. The following shape deviations were observed: round nuclei with one or more chromatin projections, pear-shaped nuclei and those of lobular shape. Spermatozoa with abnormal-shape usually had a smaller quantity of cytoplasma in which the electron-microscopy revealed structures of flagellum in the same form as in normal spermatozoa or in a structurally changed form. The structure of the nucleus of abnormal shapes is not distorted, with the exception of the presence of larger vacuoles. The chromatin of deformed spermatozoon nuclei showed a compsition similar to that in normal spermatozoa.
进行了一项电子显微镜研究，以检查用于繁殖的公鸭精子细胞核的形态异常。观察到以下形态偏差：具有一个或多个染色质突起的圆形细胞核、梨形细胞核和小叶形细胞核。形状异常的精子通常细胞质较少，电子显微镜显示其中鞭毛结构与正常精子相同或结构发生改变。除了存在较大的液泡外，异常形状细胞核的结构未变形。畸形精子细胞核的染色质组成与正常精子相似。
