Testing for Sexually Transmitted Infections (STIs) before an abortion is a critical safety step to protect your future reproductive health. Because the cervix is dilated during an abortion procedure, existing bacteria can move from the lower genital tract into the uterus, significantly increasing the risk of severe complications.
The Link Between STIs and Pelvic Inflammatory Disease (PID)
The primary risk of having an untreated STI—specifically Chlamydia or Gonorrhea—during an abortion is the development of Pelvic Inflammatory Disease (PID).
- Bacterial Transfer: During an abortion, the opening of the cervix can allow bacteria from an undiagnosed STI to travel upward.
- High Prevalence: Studies indicate that 5% to 17% of women seeking abortions may have an asymptomatic Chlamydia infection.
- Silent Symptoms: Many STIs show no visible symptoms, meaning you may be at risk without knowing it.
Long-Term Risks of Untreated Infections
If an STI is not identified and treated prior to the procedure, the resulting Pelvic Inflammatory Disease can lead to permanent damage, including:
- Chronic Pelvic Pain: Long-term abdominal discomfort due to internal scarring.
- Ectopic Pregnancy: Damage to the Fallopian tubes that can make future pregnancies life-threatening.
- Infertility: Permanent scarring that may prevent future conception.

Common STIs to Screen For
A comprehensive pre-abortion screening should include tests for:
- Chlamydia & Gonorrhea: The most common causes of post-abortion PID.
- Trichomoniasis & Syphilis: General bacterial infections that impact recovery.
- HIV, Hepatitis, & HPV: Critical for overall long-term health management.
Summary: A Proactive Safety Measure
Undergoing an STI test is a proactive step that mitigates medical risk. Identifying and treating an infection before the procedure prevents the escalation of health stressors and ensures your reproductive system is protected for the future.
