Pelvic inflammatory disease (PID) is largely preventable. Because it’s most often caused by sexually transmitted bacteria traveling from the cervix into the uterus, fallopian tubes, or ovaries, prevention centers on reducing your exposure to those bacteria, catching infections early, and protecting the natural defenses your body already has.
Understand What Causes PID
PID develops when bacteria move upward from the vagina or cervix into the deeper reproductive organs. About half of diagnosed PID cases test positive for chlamydia or gonorrhea. The other half involve a mix of bacteria that normally live in the vagina but cause problems when they migrate to places they don’t belong. This means PID prevention isn’t only about avoiding STIs, though that’s the biggest piece of the puzzle.
Bacterial vaginosis (BV), a common imbalance of vaginal bacteria, also raises PID risk. BV creates inflammation and disrupts the protective bacterial environment that helps keep harmful organisms in check. Treating BV when it occurs is one less-obvious step toward preventing PID.
Use Condoms Consistently
Condoms are the most direct barrier between you and the bacteria that cause PID. Research on women who had already experienced one episode of PID found that consistent condom use reduced the risk of recurrent PID, chronic pelvic pain, and infertility by 30% to 60%. “Consistent” in that study meant using condoms for roughly 60% of sexual encounters, so the protection likely improves with more rigorous use.
Condoms work by physically blocking the transmission of chlamydia and gonorrhea during vaginal sex. They don’t eliminate all risk, partly because some PID-associated bacteria aren’t exclusively sexually transmitted, but they remain the single most effective tool you can use on your own.
Get Screened for STIs Regularly
Chlamydia and gonorrhea frequently cause no symptoms at all, especially in the early stages. You can carry either infection for weeks or months without knowing, giving bacteria time to spread upward and trigger PID. Routine screening catches these infections before they do damage.
The CDC recommends that all sexually active women under 25 get tested for chlamydia and gonorrhea every year. Women 25 and older should also test annually if they have new partners, multiple partners, or a partner with an STI. If you test positive and get treated, follow up with another test three months later to confirm the infection hasn’t returned.
Fewer Partners Means Lower Risk
The number of sexual partners you have directly affects your odds. Women who reported four or more recent sexual partners were more than three times as likely to develop PID compared to women with one partner. This makes sense: each new partner introduces a new set of potential exposures.
Interestingly, frequent intercourse itself may also play a role even outside of STI risk. One study found that married women with a single partner who had sex six or more times per week were about three times more likely to develop PID than similar women having sex less than once per week. The likely explanation is that repeated intercourse can physically push bacteria from the lower genital tract upward. This doesn’t mean you need to limit how often you have sex, but it does reinforce the importance of making sure neither you nor your partner is carrying an untreated infection.
Make Sure Your Partners Get Treated
If you’re diagnosed with chlamydia, gonorrhea, or PID itself, your sexual partners from the previous 60 days need evaluation and treatment, even if they have no symptoms. Without partner treatment, reinfection is common and the cycle starts over.
Expedited partner therapy, where your healthcare provider gives you medication or a prescription to pass along to your partner, has been shown to reduce chlamydia reinfection by about 20% and gonorrhea reinfection by about 50% compared to simply telling partners to seek their own care. It’s not the ideal approach (partners should ideally be examined too), but it’s far better than leaving a partner untreated because they never make it to a clinic.
Don’t Douche
Douching is one of the clearest avoidable risk factors for PID. Vaginal douching strips away the protective bacteria that naturally line the vagina and act as a barrier against infection. Worse, the physical pressure of douching can push bacteria upward into the uterus and fallopian tubes, essentially delivering harmful organisms to exactly the places where PID develops.
The vagina is self-cleaning. Normal discharge handles the job. If you notice unusual odor or discharge, that’s a reason to see a provider rather than douche, because those symptoms could signal BV or an STI that needs actual treatment.
Recognize Early Warning Signs
PID often starts as a lower genital tract infection, like cervicitis (inflammation of the cervix). Catching and treating cervicitis before it progresses is a genuine prevention strategy. Symptoms to watch for include unusual vaginal discharge (especially if it’s yellow or green), bleeding between periods or after sex, pain during sex, and vaginal itching or irritation.
Some cervical infections cause no symptoms at all, which circles back to the importance of regular screening. But when symptoms do appear, they’re your early warning system. Lower abdominal pain on top of any of these signs suggests the infection may already be moving upward and warrants prompt attention.
STI Screening Before IUD Insertion
If you’re getting an intrauterine device (IUD), the insertion process can carry bacteria from the cervix into the uterus. The risk of PID is slightly elevated in the weeks immediately following insertion, then drops back to baseline. This is why providers typically screen for chlamydia and gonorrhea around the time of IUD placement. If you’re in a higher-risk group, make sure this screening actually happens before the procedure rather than being skipped.
Having an IUD does not cause ongoing PID risk. The concern is specifically about inserting a device through a cervix that’s already harboring an untreated infection.
Protect Your Vaginal Microbiome
Your vaginal bacterial environment is a genuine line of defense. A healthy microbiome, dominated by protective lactobacillus bacteria, creates an acidic environment that suppresses the growth of harmful organisms. When that balance tips toward bacterial vaginosis, the risk of both acquiring STIs and developing PID goes up.
Beyond avoiding douching, you can support vaginal health by avoiding scented soaps, sprays, or wipes in the genital area. Wearing breathable cotton underwear and changing out of wet swimwear or workout clothes promptly also helps. If you experience recurrent BV, talk to a provider about longer-term management, because each episode represents a window of increased vulnerability to PID.
