Use of the intrauterine device (IUD) is avoided because of perceived risk of pelvic inflammatory disease (PID) associated with sexually transmitted Infections (STI). Calculation of the risk of clinical pelvic inflammatory disease showed that the estimated risk was low (0.15%), even with a high STI prevalence. This estimated risk argues for making IUDs more available.
由于认为宫内节育器（IUD）与性传播感染（STI）相关的盆腔炎（PID）风险，所以避免使用它。临床盆腔炎风险的计算表明，即使性传播感染患病率很高，估计风险也很低（0.15%）。这一估计风险表明应增加宫内节育器的可及性。
