Can Chronic Cervicitis Cause Infertility? What to Know

Chronic cervicitis simply means ongoing inflammation of the cervix. Inflammation that is confined only to the cervix is not usually a direct cause of infertility ^{[1] [2]}. The cervix is the lower part of the uterus, and if inflammation stays there, it typically does not prevent pregnancy.

However, chronic cervicitis is a description of inflammation, not a single disease. Whether it affects your fertility depends on what is causing the inflammation and whether that cause has spread beyond the cervix into the upper reproductive tract ^{[3] [4]}.

The Difference Between Cervicitis and PID

Your reproductive system is connected. To understand the fertility risk, it helps to distinguish between the lower and upper reproductive tracts:

• Lower Tract (Cervicitis): Inflammation of the cervix. This usually does not cause infertility directly ^[1].
• Upper Tract (Pelvic Inflammatory Disease / PID): When an infection travels upward (ascends) into the uterus and the fallopian tubes ^[1].

Infertility is a known long-term consequence of PID, rather than cervicitis alone ^[1]. When upper-tract infections occur, they can create scar tissue in the fallopian tubes ^[5]. If the tubes become damaged or blocked (tubal occlusion), the egg and sperm cannot easily meet, increasing the risk of tubal-factor infertility ^[1]. Tubal damage also increases the risk of an ectopic pregnancy, which occurs when a fertilized egg implants outside the uterus ^[6].

Specific Infections and Your Fertility

If your cervicitis is caused by a sexually transmitted infection (STI), the risk to your fertility increases if the infection ascends.

• Chlamydia and Gonorrhea: These bacteria are commonly associated with ascending into the upper reproductive tract and causing PID ^[3]. Population studies show that people who have had chlamydia face higher risks of subsequent PID and tubal-factor infertility ^[7].
• Mycoplasma genitalium: This bacteria is also associated with PID and upper-tract inflammation ^{[8] [9]}. However, the evidence linking it directly to tubal damage is less definitive than for chlamydia and gonorrhea, and routine screening solely to prevent infertility is not firmly established ^[10].

It is important to note that many people who are treated for these infections do not become infertile and go on to have healthy pregnancies.

“Silent” Infections and the Importance of Treatment

Infections like chlamydia and gonorrhea can be mild or symptom-free ^[4]. It is possible to have an infection ascending into the upper reproductive tract without realizing it ^[1].

Prompt, appropriate treatment lowers the risk of complications, but it cannot guarantee that an infection has not already spread, nor can it undo existing tubal scarring ^[11]. This is why identifying and treating the underlying cause is so important:

• Partner Treatment: If an STI is diagnosed, your sexual partner(s) must also be evaluated and treated according to specific guidelines for that organism to prevent reinfection. (If your cervicitis has a noninfectious cause, partner treatment is not needed.) You should avoid sex until treatment is complete. Repeat infections further increase the risk of PID ^[12].
• Testing: Depending on the organism and treatment used, your doctor may recommend a test-of-cure (to confirm the current infection is gone) or retesting a few months later (to check if you have been reinfected). These serve different purposes ^[13].

When to Seek a Fertility Evaluation

A history of chronic cervicitis does not automatically mean you need an early fertility workup. Standard guidelines recommend seeking a fertility evaluation if you have not achieved pregnancy after:

• Under age 35: 12 months of regular, unprotected sex ^[14].
• Age 35 or older: 6 months of regular, unprotected sex ^[14].

However, your doctor may recommend immediate or prompt evaluation if you are over 40, have irregular ovulation, or have known risk factors like a history of PID, previous ectopic pregnancy, or known tubal disease ^{[15] [16]}.

Fertility evaluations involve both partners. It usually includes checking ovulation, assessing the male partner’s semen, and evaluating the uterus and fallopian tubes ^{[15] [17]}. To check if your fallopian tubes are open (tubal patency), doctors commonly use a specialized X-ray called Hysterosalpingography (HSG) ^[18]. While an HSG can confirm if fluid passes through the tubes, it does not rule out all microscopic damage or scarring on the outside of the tubes. Important: An HSG should never be performed while you have an active pelvic infection or active cervicitis ^[18].

⚠️ When to Seek Urgent Care

If you experience severe or new lower abdominal/pelvic pain, high fever, vomiting, abnormal discharge, or significant bleeding, seek prompt medical assessment to rule out active PID.

Seek emergency care if you know or suspect you are pregnant and experience one-sided pelvic pain, shoulder pain, fainting, marked dizziness, or heavy bleeding, as these can be signs of an ectopic pregnancy.
