Hostile Cervical Mucus and Infertility

Hostile cervical mucus is one cause of female factor infertility, though the significance of mucus hostility is still disputed by fertility specialists. In a normal cycle, the cervix produces watery mucus just prior to ovulation. This mucus assists sperm in reaching the fallopian tubes and fertilizing the egg. If the cervical mucus is too thick or viscous, it can prevent sperm from passing through the cervix. Hostile cervical mucus can also cause secondary infertility, or the inability to conceive after previously successful pregnancies.

Causes of Hostile Cervical Mucus

Some of the common causes of hostile cervical mucus are:

• Mucus containing antisperm antibodies
• Abnormal sperm or seminal fluid
• Inadequate estrogen stimulation and cervical functioning due to infection or damage

Prevention of Hostile Cervical Mucus

Because cervical mucus plays an important role in a woman's ability to get pregnant, those with hostile cervical mucus can take guaifenesin during ovulation to reduce the mucus' thickness. Guaifenesin is an ingredient in some over-the-counter cough syrups, including Robitussin.

Schedule an Appointment with a Fertility Doctor

If you and your partner are experiencing problems conceiving, it is important to meet with a fertility specialist for an exam. A fertility specialist in your area can examine both partners to determine if fertility problems are present.
