Which of the following is the failure rate of the LNG IUD under typical use?

The failure rate of the levonorgestrel (LNG) intrauterine device (IUD) under typical use is indeed approximately 0.2%. This low failure rate is reflective of the high efficacy of the LNG IUD in preventing unintended pregnancies.

The LNG IUD provides a reliable barrier and releases hormones locally within the uterus, effectively preventing ovulation, thickening cervical mucus, and thinning the endometrial lining. These mechanisms contribute to its effectiveness as a contraceptive method. Studies have demonstrated that the LNG IUD has one of the lowest failure rates of any reversible contraceptive option, making it a preferred choice for many individuals seeking long-term contraception.

Understanding the typical use failure rates of contraceptive methods is important when considering their effectiveness in real-world scenarios, as perfect use rates can differ significantly. In the context of contraceptive choices, knowing that the LNG IUD has a failure rate of 0.2% under typical use highlights its reliability and can help guide decision-making for patients seeking effective reproductive planning.
