What is cervical factor infertility?

Grant L. Campbell, MD
OBGYN (Obstetrics & Gynecology)
The cervix is the lowest portion of the uterus. The cervix produces clear and watery mucus at ovulation allowing sperm to pass into the uterus. Cervical factor infertility is a rare cause of infertility; however, prior cervical surgery (cervical biopsy, cone biopsy, loop electrosurgical excision procedure [LEEP], freezing and/or laser treatments for abnormal Pap smears, for instance) may contribute to cervical factor infertility. There are no predictive tests for it. Post-coital testing -- taking a sample of mucus during ovulation to evaluate for cervical factor -- is poor at predicting true cervical abnormalities and isn't routinely performed. Typically, intrauterine sperm insemination (IUI) to bypass any potential cervical factors is recommended.
