Which contraceptive method provides the highest theoretical and typical-use efficacy for pregnancy prevention among reversible modalities, lasting 3 to 5 years?
Answer and explanation
Correct answer: D. Subdermal etonogestrel implant or levonorgestrel intrauterine device (LARC)
- Step 1: Long-Acting Reversible Contraception (LARC), including subdermal contraceptive implants and intrauterine devices, achieves failure rates < 1%.
- Step 2: Because they do not depend on daily compliance or user adherence, their typical-use efficacy matches perfect-use efficacy.
Answer
Subdermal etonogestrel implant or levonorgestrel intrauterine device (LARC).
Why not the others: 'Combined oral contraceptive pill (COCP)' has a typical-use failure rate of roughly 7% due to missed pills and gastrointestinal malabsorption; 'Male latex condoms' have a typical-use failure rate of 13%; 'Coitus interruptus (withdrawal method)' has a typical-use failure rate of over 20%.
