A 27-year-old woman has an intrauterine contraceptive device inserted. Her theoretical risk of pelvic inflammatory disease is highest during which period?
- A Between 1 and 3 months after insertion
- B First 20 days after insertion ✓
- C Between 3 and 6 months after insertion
- D Risk remains uniformly elevated throughout use
Correct answer: B. First 20 days after insertion
Explanation
The risk of PID with an IUD is concentrated in the first 20 days after insertion, reflecting contamination of the uterine cavity at the time of insertion rather than the device itself acting as a long-term nidus. After this window the risk falls to near baseline. This fact underpins advice to screen and treat cervical infection before insertion where prevalence is high.
