Chlamydia, often called the "silent STI," is one of the most common sexually transmitted infections, yet many people are unaware of its long-term consequences. Left untreated, it can lead to pelvic inflammatory disease (PID), chronic infection, and infertility—an issue that affects millions of women. However, the good news is that chlamydia-driven infertility is largely preventable through regular testing and early treatment.
The Hidden Impact of Chlamydia
In 2023 alone, 1.6 million cases of chlamydia were reported in the U.S., and experts estimate that twice as many cases went undetected. Because up to 75% of women with chlamydia experience no symptoms, the infection often remains unnoticed until it causes serious reproductive health complications.
One in 10 women with untreated chlamydia will develop PID, increasing the risk of infertility.
For every 150 untreated infections, at least one woman will become permanently sterile.
Chlamydia-related infertility costs the U.S. about $135 million annually in medical expenses.
For women who want children, infertility can be emotionally and financially devastating. It is a leading cause of anxiety, depression, and relationship stress. Treatment options, such as in vitro fertilisation (IVF), are expensive and not always successful, making prevention a much easier and more affordable solution.
Testing and Treatment: A Simple Solution
Chlamydia is easily diagnosed with a routine STI test and treated with a single course of antibiotics. The challenge is that too few women are tested regularly. The CDC recommends:
Annual testing for all sexually active women under 25.
Testing for women over 25 with new or multiple sexual partners or a known STI exposure.
Despite these guidelines, only about half of women who should be tested actually get screened. The stigma around STIs, lack of education, and limited access to testing all contribute to the problem.
The Need for More Accessible Testing
To improve chlamydia detection, new testing options are becoming available:
At-home STI test kits allow women to collect their own samples and send them to a lab for analysis.
A rapid 15-minute chlamydia test is currently in development, which could allow for immediate results in clinics or even over-the-counter availability.
Faster in-office testing exists but is underused due to low insurance reimbursement rates.
Expanding access to these testing methods and increasing public awareness could prevent thousands of cases of chlamydia-related infertility each year.
A Call for National Action
From 1993 to 2013, the U.S. government funded the National Infertility Prevention Project, which provided free or low-cost STI screening and treatment. A similar program today could dramatically improve women’s reproductive health.
Every 1% increase in federal STI prevention funding has been linked to a 0.17% drop in chlamydia rates.
Doubling current federal funding could prevent over 2,200 cases of infertility caused by chlamydia each year.
Given the importance of reproductive health, addressing preventable infertility must become a national priority. By increasing education, expanding access to STI testing, and investing in prevention efforts, we can protect women's fertility and improve overall public health.
