Gonorrhea is preventable. The most effective strategy combines barrier methods during sex, regular screening, and prompt treatment of both you and your partners. No single approach eliminates risk entirely, but layering several methods together offers strong protection.
Condoms and Barrier Methods
Consistent condom use is the most accessible form of protection. A study in the American Journal of Epidemiology found that people who used condoms every time they had sex with an infected partner had a 58% lower rate of gonorrhea and chlamydia compared to those who didn’t. That’s meaningful, but it’s not 100%, which is why condoms work best alongside other strategies like testing and limiting the number of partners.
The key word is “consistent.” Occasional use offers far less protection. Use a new latex or polyurethane condom for every act of vaginal, anal, or oral sex, from start to finish. Avoid oil-based lubricants (lotion, petroleum jelly, cooking oil), which weaken latex and cause breakage. Water-based or silicone-based lubricants are safe choices.
Gonorrhea also spreads through oral sex, a route many people overlook. For oral contact with the vagina or anus, dental dams provide a barrier. These are thin latex or polyurethane sheets placed flat over the area before oral sex begins. If you don’t have a dental dam, you can make one by cutting the tip and base off a condom, then slicing down one side and laying it flat. Use a new one each time, don’t stretch it, and skip spermicides, which can cause irritation without offering any STI protection.
Why Spermicides Don’t Help
Products containing nonoxynol-9, a common spermicide, do not protect against gonorrhea. Two randomized trials confirmed that nonoxynol-9 failed to prevent gonorrhea or chlamydia infections. In fact, frequent use can irritate genital tissue, potentially making transmission easier. If you’re relying on spermicide for STI prevention, it isn’t working.
How Often to Get Tested
Regular screening catches infections you can’t feel. Gonorrhea often causes no symptoms, especially in women and in throat or rectal infections. Untreated, it can lead to serious complications including pelvic inflammatory disease, infertility, and increased vulnerability to HIV. Testing and treating early breaks the chain of transmission.
The CDC recommends the following screening intervals:
- Women under 25: Annual screening if sexually active.
- Women 25 and older: Annual screening if you have a new partner, multiple partners, a partner with concurrent partners, inconsistent condom use outside a mutually monogamous relationship, a previous STI, or a history of exchanging sex for money or drugs.
- Men who have sex with men: At least annually at all sites of contact (urethra, rectum, throat), regardless of condom use. Every 3 to 6 months if at increased risk.
- People with HIV: At first HIV evaluation, then at least annually. More frequent testing may be appropriate based on sexual activity.
- Transgender and gender diverse people: Screening based on anatomy and sexual behavior. For example, anyone with a cervix who is under 25 should be screened annually.
- Pregnant women: All pregnant women under 25, and those 25 and older with risk factors, should be screened. Retesting is recommended in the third trimester and again within 3 months after treatment if positive.
Heterosexual men at low risk don’t have a routine screening recommendation, but testing makes sense after unprotected sex with a new or casual partner, or if a partner tests positive.
Treating Partners to Prevent Reinfection
One of the most common ways people get gonorrhea again is from an untreated partner. If you test positive, your current sexual partners need treatment too, even if they have no symptoms. This prevents a cycle of passing the infection back and forth.
Expedited Partner Therapy makes this easier. Your healthcare provider can give you a prescription or medication to bring directly to your partner, without requiring them to come in for a separate exam first. The CDC considers this a useful option, particularly for male partners of women diagnosed with gonorrhea. It’s legal in most U.S. states, though rules vary. After treatment, the CDC recommends retesting yourself in 3 months to confirm the infection hasn’t returned.
Antibiotic Prophylaxis After Exposure
A newer prevention tool called doxy-PEP involves taking an antibiotic within 72 hours after unprotected sex. The CDC issued clinical guidelines for this approach in 2024, aimed primarily at men who have sex with men and transgender women who are on HIV prevention medication or living with HIV.
For gonorrhea specifically, the results are mixed. Three large trials showed doxy-PEP reduced syphilis and chlamydia infections by more than 70%, but its effect on gonorrhea was smaller and less consistent, roughly a 50% reduction in some study populations. Two trials involving men who have sex with men found significant reductions in gonorrhea (about 55% lower risk), while a trial in cisgender women in Kenya found no benefit at all.
The recommended dose is 200 mg taken as soon as possible after sex, with no more than one dose in a 24-hour period. This is not a replacement for condoms, and it’s not currently recommended for everyone. If you’re in a higher-risk group, it’s worth discussing with your provider as an additional layer of protection.
Vaccination: Partial Protection From an Unexpected Source
There is no vaccine designed specifically for gonorrhea, but a vaccine developed to prevent meningitis B has shown unexpected cross-protection. The bacteria that cause gonorrhea and meningitis B are close relatives, and the meningitis B vaccine appears to generate some immune response against gonorrhea as well.
A meta-analysis found that receiving at least one dose of this vaccine was about 32% effective against gonorrhea. Two doses provided 33 to 40% effectiveness, while a single dose offered around 26%. Protection may fade after about three years. These numbers are modest, but for people at high risk of repeated gonorrhea infections, even partial protection adds value on top of other strategies.
This vaccine is already recommended for adolescents and young adults to prevent meningitis. The potential gonorrhea benefit is an added reason to stay current on it, though it’s not yet approved or marketed as a gonorrhea vaccine.
Reducing Risk Through Sexual Behavior
Beyond specific tools and medications, some straightforward behavioral choices lower your gonorrhea risk. Reducing the number of sexual partners limits your exposure. Being in a mutually monogamous relationship with a partner who has tested negative eliminates the risk almost entirely. Avoiding sex while you or a partner are being treated for an STI prevents transmission during the most infectious period.
Open communication with partners about testing and sexual health, while sometimes awkward, is one of the most practical prevention steps available. Knowing a partner’s recent test results, or getting tested together, gives you real information to act on rather than assumptions.
