TL;DR

Cervicitis is inflammation of the cervix — the lower end of the uterus that opens into the vagina. It often causes no symptoms at all, which is why it is frequently discovered by chance during a pelvic exam. When symptoms do appear, they include atypical vaginal discharge, bleeding between periods or after sex, and pain during sex. Sexually transmitted infections (STIs) such as chlamydia and gonorrhea are common causes, but allergies, chemical irritants, and bacterial overgrowth also trigger it. Infections need treatment, usually antibiotics; noninfectious causes clear once the irritant is removed.

Quick Answer

What is cervicitis and how is it treated? Cervicitis is swelling and irritation of the cervix. When it is caused by an STI like chlamydia or gonorrhea, both partners need antibiotic treatment. When it is caused by a reaction to products such as spermicide or hygiene sprays, no medicine is needed — stopping the product clears the inflammation. Up to 80% of cases cause no symptoms, so screening and prompt pelvic evaluation matter. Untreated STI-related cervicitis can spread to the uterus and fallopian tubes and cause pelvic inflammatory disease (PID), which can affect fertility.

What is cervicitis?

Cervicitis is irritation and swelling — medically called inflammation — of the cervix. The cervix is the lower, narrow end of the uterus that opens into the vagina [1].

The condition can be acute (sudden, usually infection-caused) or chronic (lasting three months or longer, typically linked to noninfectious sources) [3]. Both forms can look the same on exam: with cervicitis, the cervix appears red and irritated and may have pus-like discharge [1].

Key facts at a glance

| Fact | Detail | Source | |---|---|---| | Definition | Inflammation of the cervix, the lower end of the uterus | [1] | | Who it affects | Sexually active people with a cervix; highest incidence in women aged 15–24 | [3] | | Symptom rate | Up to 80% of patients have no symptoms | [3] | | Most common infectious causes | Chlamydia, gonorrhea, trichomoniasis, genital herpes | [1] [3] | | Main treatment | Antibiotics for STI causes; irritant removal for allergic causes | [2] |

How cervicitis changes the appearance of the cervix — the tissue becomes red and irritated, and pus-like discharge may form.

How common is cervicitis?

Cervicitis is among the most common conditions seen in women's health clinics. Exact prevalence is hard to pin down because it often causes no symptoms and definitions vary across studies [3].

Research gives a clear picture of the scale. Cervicitis may affect 30% to 40% of patients seen in STI clinics, and incidence is highest in sexually active people aged 15 to 24 [3]. One study of randomly selected women found a 40% prevalence of cervicitis [7].

The infections most often behind it are widespread. The Centers for Disease Control and Prevention reported 1,515,985 chlamydia cases and 543,409 gonorrhea cases in the U.S. in 2024 — more than 2.2 million combined cases of chlamydia, gonorrhea, and syphilis that year [4] [5]. Chlamydia is the most reported STI in the country and the infection most commonly linked to cervicitis.

What are the symptoms of cervicitis?

Most often, cervicitis causes no symptoms. Many people learn they have the condition only after a pelvic exam performed for another reason [1].

When symptoms do occur, they typically include:

Atypical vaginal discharge — fluid that is not typical for you (some discharge is normal)
Frequent, painful urination
Pain during sex
Bleeding between menstrual periods
Bleeding after sex that is not linked to a period [1]

Symptom summary

| Symptom | What it looks like | How common | |---|---|---| | Atypical discharge | Unusual fluid from the vagina; may look like pus | Common when present | | Painful or frequent urination | Burning or urge to urinate often | Less common | | Pain during sex | Discomfort with intercourse or pelvic exam | Reported symptom | | Bleeding between periods | Spotting outside menstrual cycle | Reported symptom | | Bleeding after sex | Postcoital bleeding unrelated to a period | Reported symptom | | No symptoms | Discovered only at pelvic exam | Up to 80% of cases |

When should you see a doctor?

See a healthcare professional if you have fluid from the vagina that is not typical, vaginal bleeding that is not a period, or pain during sex [1].

These symptoms overlap with vaginitis and other common conditions, so an exam is the fastest way to identify the cause — and the only way to catch cervicitis that produces no symptoms at all [3].

Seek evaluation promptly if you are at higher risk (new or multiple partners, a partner diagnosed with an STI, or a personal history of STIs), since untreated cervicitis can spread to the upper reproductive tract [1] [3].

What causes cervicitis?

Cervicitis has two broad cause categories: infectious and noninfectious.

Infectious causes. Sexual contact spreads infections that cause cervicitis. The common STIs involved are gonorrhea, chlamydia, trichomoniasis, and genital herpes [1]. In 30% to 50% of infectious cases, Neisseria gonorrhoeae or Chlamydia trachomatis are present, and chlamydia-related cervicitis is 4 to 5 times more common than gonococcal cervicitis [3]. Less common infectious triggers include Mycoplasma genitalium, HSV, trichomonas, and HPV [3].

Noninfectious causes. A reaction to chemicals — such as those in some birth control methods or feminine hygiene products like douches and deodorants — or an allergy to latex in condoms can lead to cervicitis [1]. Overgrowth of bacteria already in the vagina, called bacterial vaginosis, is another noninfectious cause [1]. Mechanical irritants such as pessaries, cervical caps, or tampons can also trigger inflammation [3].

The three cause categories of cervicitis — infections are the best-known trigger, but allergies and bacterial overgrowth account for many cases too.

What are the risk factors for cervicitis?

You are at greater risk of cervicitis if you have high-risk sex — for example, sex without protection, sex with a partner who is at high risk, or sex with more than one partner [1].

Other established risk factors include beginning sexual activity at an early age and having a history of STIs [1] [3]. Studies add further behavioral risks: having a new sex partner, a partner with concurrent sexual partners or an STI diagnosis, inconsistent condom use outside a mutually monogamous relationship, and HIV infection [3].

Risk factor checklist

| Risk factor | Why it raises risk | Source | |---|---|---| | Unprotected sex | No barrier against STI transmission | [1] | | Multiple or new partners | More exposure opportunities | [1] [3] | | Partner with STI or concurrent partners | Direct or indirect exposure | [1] [3] | | Early sexual debut | Longer exposure window | [1] | | History of STIs | Prior infection history | [1] | | Age 15–24 | Highest incidence age group | [3] | | HIV infection | Immune-related susceptibility | [3] |

What complications can cervicitis cause?

The main complication is the infection spreading upward into the uterus.

If gonorrhea or chlamydia cause cervicitis, the infection may spread to the uterine lining and the fallopian tubes. This is called pelvic inflammatory disease (PID). If PID is not treated, it can cause problems having a baby [1].

Cervicitis also raises the risk of acquiring HIV from a sex partner who has HIV, because inflamed cervical tissue makes transmission easier [1].

How is cervicitis diagnosed?

Diagnosis begins with a physical exam. It includes two parts [2]:

Pelvic exam. The clinician checks the pelvic organs for swelling and tenderness. A speculum — an instrument placed in the vagina to hold it open — helps the clinician see the walls of the vagina and the cervix [2].
Fluid sampling. A small cotton swab or brush collects cervical and vaginal fluid, which goes to a lab to test for infections. A urine sample may also be tested [2].

One important caveat from the research literature: in more than half of all cases, the exact cause cannot be determined, because differentiating inflammation from mechanical or chemical irritants from infectious inflammation is not clinically possible. In one randomized trial, 61% of enrolled women tested negative for chlamydia, gonorrhea, trichomonas, and Mycoplasma by nucleic acid amplification testing (NAAT) [3] [7].

Diagnostic workup

| Step | What happens | What it shows | Source | |---|---|---|---| | Pelvic exam | Speculum visualizes cervix; gloved exam checks tenderness | Red, irritated cervix; swelling | [2] | | Cervical fluid sample | Swab or brush collection, sent to lab | Identifies STI pathogens | [2] | | Vaginal fluid sample | Same collection | Checks for vaginitis/BV overlap | [2] | | Urine test | Urinalysis | UTI overlap or STI testing | [2] | | NAAT (if performed) | Lab nucleic acid test | Confirms or rules out chlamydia/gonorrhea/trichomonas; negative in 61% of one trial | [3] [7] |

How is cervicitis treated?

Treatment depends entirely on the cause — and some cases need no medicine at all.

No treatment needed. Cervicitis caused by a reaction to products such as spermicide or feminine hygiene products requires no medication. Stopping use of the offending product clears the irritation [2].

Antibiotics. For cervicitis caused by an STI, both you and your partner will need treatment, usually with antibiotics. Healthcare professionals prescribe antibiotics for gonorrhea, chlamydia, and trichomoniasis [2].

Antivirals. If genital herpes is the cause, antiviral medicine may be offered to cut the duration of symptoms. There is no cure for herpes — it is a long-term condition that can be passed to a sexual partner [2].

Follow-up. Repeat testing may be suggested after gonorrhea or chlamydia treatment to confirm the infection has cleared [2].

Treatment by cause

| Cause | Treatment | Partner treatment? | Follow-up | Source | |---|---|---|---|---| | Spermicide / hygiene products | None — stop the product | Not needed | Not needed | [2] | | Chlamydia | Antibiotics | Yes, both partners | Repeat testing may be offered | [2] | | Gonorrhea | Antibiotics | Yes, both partners | Repeat testing may be offered | [2] | | Trichomoniasis | Antibiotics | Yes, both partners | Repeat testing may be offered | [2] | | Genital herpes | Antivirals (shortens symptoms) | Not treated unless symptomatic | None; long-term condition | [2] |

Treatment follows the cause — STI-driven cervicitis always requires treating both partners.

How can you prevent cervicitis?

To reduce the risk of STI-related cervicitis, use condoms every time you have sex. Condoms help prevent the spread of gonorrhea and chlamydia, the STIs most likely to lead to cervicitis [1].

Being in a long-term relationship in which both partners do not have sex with anyone else also lowers STI risk [1]. Avoiding known chemical irritants — douches, scented hygiene products, and allergens like latex if you are sensitive — addresses the noninfectious causes [1] [3].

What should you do before your appointment?

If you have symptoms, make an appointment with your main healthcare professional or a gynecologist. Preparation helps the visit go smoothly [2]:

Note your symptoms and when they began.
Note your sex partners and when you had sex.
List all allergies, and all medicines, vitamins, and supplements with doses.
Write down your questions, such as how the condition developed, whether medicine is needed, whether your partner needs testing or treatment, what to do if symptoms return, and how to prevent recurrence [2].

In the meantime, avoid sex, use pads instead of tampons, and do not douche [2]. Expect questions about sexual activity, STI history, pain or bleeding during sex, hygiene product use, spermicide use, and possible pregnancy [2].

The bottom line

Cervicitis is common, frequently symptom-free, and highly treatable. Most often it stems from STIs like chlamydia or gonorrhea — which makes partner treatment and safe-sex habits essential — but allergies, chemicals, and bacterial overgrowth cause many cases that resolve simply by removing the irritant.

The real danger is ignoring it. Because up to 80% of cases cause no symptoms, routine pelvic exams and prompt evaluation of atypical discharge, unusual bleeding, or pain during sex are the best protection. Left untreated, STI-related cervicitis can spread into the uterus and fallopian tubes and cause pelvic inflammatory disease, which can affect fertility.

If you have atypical discharge, bleeding between periods, or pain during sex — or if a partner has been diagnosed with an STI — see a healthcare professional for an exam. A quick pelvic exam and fluid test can identify the cause, and most cases clear with a short antibiotic course.

Frequently asked questions

Can cervicitis go away on its own?

Sometimes. If the cause is a chemical irritant or allergy — such as spermicide, douching products, or latex — stopping the product usually clears the inflammation without any medicine. But cervicitis caused by an STI does not resolve reliably on its own and needs antibiotics to prevent it spreading to the uterus and fallopian tubes.

Is cervicitis an STI?

Cervicitis itself is not an STI — it is inflammation of the cervix with many possible causes. However, STIs such as chlamydia, gonorrhea, trichomoniasis, and genital herpes are among the most common triggers, so cervicitis is often a sign that STI screening is warranted.

Can you have cervicitis and not know it?

Yes. Up to 80% of people with cervicitis have no symptoms at all, and the condition is often discovered only during a pelvic exam performed for another reason. This is why routine screening matters for sexually active people.

Does cervicitis cause infertility?

Cervicitis itself does not damage fertility, but untreated STI-related cervicitis can spread to the uterine lining and fallopian tubes, causing pelvic inflammatory disease (PID). Untreated PID can cause fertility problems. Treating the underlying infection promptly prevents this complication.

Can a partner treat cervicitis if I have it?

If the cause is an STI, your partner needs treatment too — usually the same antibiotic course — to prevent passing the infection back and forth. Do not resume sex until both partners have completed treatment.

Can you get cervicitis without being sexually active?

Yes. Noninfectious causes such as allergic reactions to latex or hygiene products, chemical irritants, bacterial overgrowth (bacterial vaginosis), and mechanical irritation can all cause cervicitis in people who are not sexually active.

What does cervicitis discharge look like?

The discharge is typically atypical for you — it may be increased in volume, off-color, or pus-like. With cervicitis, the cervix often looks red and irritated and may show discharge resembling pus on exam. Normal vaginal discharge varies day to day and is usually clear or white without odor; new, persistent changes warrant evaluation.

Is cervicitis serious?

Most cases are mild and easily treated. The seriousness depends on the cause: STI-driven cervicitis is the form that requires prompt attention because it can spread upward and cause pelvic inflammatory disease, which can affect fertility, and it also raises the risk of HIV transmission from a partner.
