The single biggest reason routine STI screening matters is also the least intuitive: most people with a sexually transmitted infection don’t have symptoms. That means “I feel fine” isn’t reliable evidence that nothing’s going on, and screening on a schedule — rather than only when something feels wrong — is how these infections actually get caught.
Why Screening Without Symptoms Is the Standard, Not the Exception
Chlamydia and gonorrhea, two of the most commonly reported bacterial STIs in the United States, are frequently asymptomatic, particularly in women. Left untreated, they’re recognized causes of pelvic inflammatory disease, which can in turn affect fertility. That downstream risk is a big part of why screening guidance is built around routine testing rather than symptom-triggered testing.
General CDC Screening Guidance
The CDC recommends annual chlamydia and gonorrhea screening for all sexually active women under 25, and continued annual screening for women 25 and older who have risk factors such as a new sex partner, multiple partners, or a partner known to have an STI. Recommendations for other populations, including men and gender-diverse people, vary by anatomy and risk factors, which is exactly why a personalized checklist — built around your own anatomy, sexual practices, and history — is more useful than a single generic list. We’re building that detailed checklist as a dedicated guide; this page is the framework it sits under.
STI Screening and Pregnancy
STI screening is also a standard part of prenatal care, since certain untreated infections can affect a pregnancy or be passed to a baby. If you’re in the preconception or early pregnancy stage, this is usually addressed as part of that broader visit rather than as a separate appointment — see our Pregnancy & Preconception guide for more on what that visit typically covers.
What to Bring Up With a Provider
Because the right testing panel depends on individual factors, the most useful thing you can do before an appointment is be specific and direct about your sexual history and practices — anatomy involved, number of partners, condom use, and any known exposures. Providers can only tailor screening to what they actually know, and STI screening is one area where more detail genuinely changes the recommendation.
