Correct option is A
Sol. The Levonorgestrel-releasing intrauterine contraceptive device (LNG-IUCD), such as Mirena, is approved for effective use up to five years. After this period, its contraceptive efficacy diminishes, necessitating replacement to maintain effective birth control. Recent studies suggest that some LNG-IUCDs may remain effective up to eight years; however, the standard recommendation remains five years.
Explanation of each option:
· (a) Five years – Correct answer. This is the approved duration for LNG-IUCD effectiveness. After five years, the device should be replaced to ensure continued contraceptive efficacy.
· (b) Ten years – This duration is typically associated with copper-based IUCDs, not LNG-IUCDs. Using an LNG-IUCD beyond its approved duration without replacement may result in reduced contraceptive effectiveness.
· (c) Fifteen years – No intrauterine contraceptive devices are approved for this duration. Extending use beyond the recommended period without replacement increases the risk of unintended pregnancy.
· (d) Twenty years – This exceeds the lifespan of any current IUCD. Relying on an IUCD for such an extended period without replacement is not supported by clinical guidelines and may compromise contraceptive efficacy.
