Short-tailed spermatozoa were found in 3 men attending our subfertility clinic. Light microscopy revealed basically normal sperm heads, but a short tail was found in 90% or more of the spermatozoa. Scanning and transmission electron-microscopic examinations of the ejaculate revealed several types of short-tailed spermatozoa. In one case, the majority of the spermatozoa had a short, thick tail. In another case, all the spermatozoa were short-tailed, although two different types could be distinguished. As in the first case some spermatozoa were short- and thick-tailed, whereas others possessed an incomplete neck and middle piece, and a short, thick principal piece. In the third case, an elongated middle piece and short principal piece were found in almost all the short-tailed spermatozoa. Our electron-microscopic study revealed that the type of short-tailed spermatozoa was different in each patient.
在我院不育门诊就诊的3名男性中发现了短尾精子。光学显微镜检查显示精子头部基本正常，但90%或更多的精子存在短尾。对射精样本进行扫描电子显微镜和透射电子显微镜检查发现了几种类型的短尾精子。在一个病例中，大多数精子的尾巴短而粗。在另一个病例中，所有精子均为短尾，尽管可区分出两种不同类型。与第一个病例一样，一些精子的尾巴短而粗，而另一些精子的颈部和中段不完整，主段短而粗。在第三个病例中，几乎所有短尾精子都有拉长的中段和短的主段。我们的电子显微镜研究表明，每个患者的短尾精子类型不同。
