A 23-year-old woman who had one documented episode of pelvic inflammatory disease at age 19 now presents with bilateral tubal block on hysterosalpingography. According to classic cohort data on PID sequelae, the approximate risk of tubal factor infertility after a single episode of PID is closest to:
- A About 10 percent ✓
- B About 5 percent
- C About 25 percent
- D About 50 percent
Correct answer: A. About 10 percent
Explanation
Classic follow-up data from Westrom's cohort showed tubal infertility in approximately 11 percent of women after one episode of PID, rising to about 23 percent after two episodes and about 54 percent after three episodes. The 25 percent figure corresponds to recurrence after two episodes and the 50 percent figure to three or more episodes, so students who remember the escalating pattern but not the baseline will be drawn to those options.
