Cervical mucous is usually thick and is present to keep infection out of the uterus. Around the time of ovulation it becomes thin and watery to assist the sperm through the uterus and on to the fallopian tubes to fertilize the egg. This test may provide insight as to why successful fertilization is not occurring. This test is sometimes called the Sims-Huhner test, named after the healthcare providers who invented it.
The post-coital test (PCT) evaluates not only the cervical mucous but also the interaction of the sperm and the mucous. If properly timed (as directed by the healthcare provider), the test provides information about the adequacy of a woman’s cervical mucous production, the ability of the sperm to survive in the cervical mucous, and how the sperm and cervical mucous interact. Ideally, the sperm have no trouble moving through the cervical mucous.
This test must be performed right around the time of ovulation (when eggs are released). In your healthcare provider’s office a sample of cervical mucous is gently removed from the cervix two to eight hours after intercourse during a normal pelvic exam and evaluated microscopically.
There are only a few days during the menstrual cycle when the sperm can survive in the cervical mucous, so the timing of this test is crucial.
