Problems With The Cervix And Uterus Diagnosis Treatment Hostile Cervical Mucus Explanation Cervical mucus must be of the right consistency and pH to welcome sperm and help the sperm travel from the vagina into the uterus. If the mucus becomes too acidic it will kill the sperm. Cervical mucus can become hostile to the sperm as a result of infections, trauma or antibodies. Bacteria or viruses can invade the cervix and the infected cervical mucus becomes a barrier to the sperm's travel. Past procedures or surgeries to the cervix can scar the mucus producing glands of the cervix.
Antibodies are our body's natural defense to invaders.
Antibodies cling to invaders and immobilize the invaders. For unknown reasons, some women create antibodies that attack sperm. Symptoms Infections may produce symptoms of fever, pain, or discharge. Some infections don't produce any symptoms at all. If trauma or antibodies are to blame for the cervical mucus, there probably won't be any symptoms and diagnosis will require specific tests.
