POST-COITAL TEST DETERMINES QUALITY OF CERVICAL MUCUS
fertilization. However, in some cases, there is an incompatibility between the sperm and cervical mucus, causing the sperms to become immobile or die, thus preventing fertilization.
It evaluates the interaction between the sperm and cervical mucus at a time near ovulation to determine if an incompatibility exists. The PCT is a poor predictor of pregnancy success, but may be useful to determine the need for Intrauterine Insemination (IUI).
If after the initial workup and evaluation tests, it has been established that the female partner is ovulating properly, her tubes are not blocked and the Male Partner’s semen analysis is normal, Doctor’s may order a Post Coital Test to rule out any other cervical mucus related abnormalities using this test.
Post Coital Test is done 1 to 2 days before ovulation when the cervical mucus is thin and stretchy and sperm can easily move through it into the Uterus. The test is done within 2 to 8 hours after you have intercourse as an outpatient procedure. During the test a speculum exam will be performed and a small amount of cervical mucus will be withdrawn from the cervix.
A pelvic examination to collect a cervical mucus sample does not cause problems.
If hostile cervical mucus is documented on two occasions, IUI is advised.
Abstinence: 3 day abstinence from intercourse is necessary before the test
One negative test does not carry any significance. It is advised that the test should be repeated in another cycle ensuring all pre-requisites are met (ovulation, abstinence, intercourse)
