Abstract

Postcoital tests (PCTs) were conducted following artificial insemination with either live or dead spermatozoa. The cervical mucus samples were analyzed for sperm counts and acid phosphatase activity. The results indicate that the final distribution of mucus and sperm in the PCT sampling catheter is not truly representative of their original distribution within the cervix. Moreover, PCTs done after insemination with semen containing only dead sperm yield unrealistically high sperm counts and high cervical mucus acid phosphatase levels. This is apparently due to the translocation of semen from the area of the external os into the mucus sample by the sampling catheter. This problem can be largely prevented by removing a plug of mucus from the external os prior to the catheter sampling procedure.

摘要

在使用活精子或死精子进行人工授精后进行了性交后试验（PCT）。对宫颈黏液样本进行了精子计数和酸性磷酸酶活性分析。结果表明，PCT采样导管中黏液和精子的最终分布并不能真正代表它们在宫颈内的原始分布。此外，用仅含死精子的精液进行授精后进行的PCT显示精子计数过高且宫颈黏液酸性磷酸酶水平过高，这是不切实际的。这显然是由于采样导管将精液从外口区域转移到了黏液样本中。在导管采样程序之前从外口取出一团黏液，可在很大程度上防止这个问题。
