A 30-year-old woman with a copper intrauterine device inserted four months ago develops pelvic inflammatory disease. Regarding the role of the IUD in this infection, which statement is CORRECT?
- A Excess PID risk is confined largely to the first three weeks after insertion ✓
- B The IUD continuously elevates PID risk throughout its use
- C The IUD protects against PID by inducing thick cervical mucus
- D The device must always be removed before starting antibiotics
Correct answer: A. Excess PID risk is confined largely to the first three weeks after insertion
Explanation
The excess risk of PID with an IUD is concentrated in the first 20 days after insertion, when insertion itself can carry cervical organisms into the upper genital tract. After this window the risk returns close to baseline. The hormonal IUD, not the copper device, thickens cervical mucus. Current guidance allows the IUD to be left in place and treated in situ in mild disease, so removal is not mandatory.
