Postcoital test for cervical factor assessment

The consistency of the cervical fluid or mucus can hinder or prevent the entry of spermatozoa and, therefore, prevent fertilization from taking place.

The postcoital test consists of taking a sample of cervical mucus after sexual intercourse to see under the microscope what the mucus-sperm interaction is like. During the woman's fertile days, the cervical fluid should be fluid and allow the passage of sperm. If there is any cervical alteration, it can be observed how the mucus obstructs the passage of sperm.
