Sperm morphology was examined in fresh ejaculates accepted for insemination. The material included 161 ejaculates of 36 male silver foxes. Samples were fixed, stained with eosin/nigrosin and evaluated microscopically. The abnormal spermatozoa were categorized by the location of the defect. The mean (+/- SD) percentage of morphologically normal spermatozoa was 87.55 +/- 10.45. The incidence of sperm defects was low and variation high in all defect classes. Defects of tails of spermatozoa accounted for > 50% of the abnormalities found. Morphological quality did not correlate with the volume of the sperm-rich fraction, mass activity, progressive motility, or total sperm count in ejaculates of acceptable sperm quality. The incidence and effects of morphological defects in low-quality semen remain to be studied.
对用于授精的新鲜精液进行了精子形态学检查。材料包括36只雄性银狐的161份精液。样本进行固定，用伊红/黑色素染色并进行显微镜评估。异常精子根据缺陷位置进行分类。形态正常精子的平均（±标准差）百分比为87.55±10.45。在所有缺陷类别中，精子缺陷的发生率较低但变异度较高。精子尾部缺陷占所发现异常的50%以上。形态质量与精子质量合格的精液中富含精子部分的体积、群体活动、渐进性运动或总精子数无关。低质量精液中形态缺陷的发生率和影响仍有待研究。
