Diligent analysis of PF 10 to 20 hours after midcycle intracervical insemination with husband's semen in couples with unexplained infertility showed that sperm are consistently able to transverse the reproductive tract in this group of patients. However, this finding does not necessarily imply that the sperm were retained at the site of fertilization or that they were competent to achieve oocyte fertilization. Therefore, further experiments obtaining sperm from the tubal isthmus to assess the effects of their sequestration there on their ability to fertilize human oocytes are needed.
