The test is performed in the office. A speculum is placed in the vagina, as it would be for a pap smear. A syringe without a needle is then used to remove some mucus from the cervical opening. The speculum is then removed and the cervical mucus is evaluated under a microscope to look for the presence or absence of swimming sperm. There have been many studies suggesting that the test is neither accurate nor predictive of fertility. Many fertility specialists skip this step and proceed directly to intrauterine insemination. However, for certain patients this test can be very useful and provide essential information.
