The Huhner test is a type of fertility test in which the compatibility of sperm and cervicalmucus is evaluated. This is an important test because up to 8% of infertility cases are related to incompatibility between cervical mucus and sperm. The Huhner test, also known as the Sims-Huhner test or the postcoital test, is carried out by an infertility diagnostician, who examines these fluids several hours after intercourse has taken place.
