What is hostile cervical mucus?

Minute glands in the cervix excrete a jelly-like substance known as cervical mucus.  The consistency of this mucus varies throughout a woman's cycle.  Around the time of ovulation, cervical mucus is at its thinnest, clearest and most abundant.  Cervical mucus is a significant factor in a couple's ability to get pregnant.  Sperm can survive up to 72 hours in this type of cervical mucus.

Hostile cervical mucus is too thick for the sperm to penetrate the cervix, thus preventing conception. Among the causes of hostile cervical mucus are Clomid, a drug prescribed to induce ovulation.

The best way to counteract hostile cervical mucus is through the use of guaifenesin.  Guaifenesin is one of the main ingredients in Robitussin cough syrup.  Robitussin is readily available over-the-counter.  When purchasing robitussin, make sure to pick the variety that includes only guaifenesin, as many varieties contain other medicines.  It is recommended that you take 2 teaspoons three times per day.  If after this the mucus still appears thick, you can take as the maximum dosage as listed on the label of the cough medicine. You should increase your intake of water to spur more cervical mucus production as well.

Many doctors suggest taking Robitussin five days before and including the day of ovulation for a total of 6 days during your cycle.  This helps provide the optimal environment to help the sperm survive and get to where they need to go.  If you take Clomid, waiting until the day after the last Clomid pill is taken before starting Robitussin is suggested.

Guaifenesin is also available in pill format, but this format usually requires a Doctor's prescription.
