IUCD lasting for 10 years is:
**Core Concept**
The question is testing the knowledge of long-acting reversible contraceptive devices (LARCs), specifically intrauterine devices (IUCDs). IUCDs are a type of LARC that can provide contraceptive protection for several years.
**Why the Correct Answer is Right**
The 10-year-lasting IUCD is likely referring to the levonorgestrel-releasing intrauterine system (LNG-IUS), also known as Mirena. The LNG-IUS releases a small amount of the progestin levonorgestrel, which is absorbed by the uterine lining, creating a thin and atrophic endometrium, thereby preventing implantation of a fertilized egg. The hormone also reduces menstrual bleeding and has a potential therapeutic effect on treating heavy menstrual bleeding and endometriosis.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because there are other types of IUCDs with varying durations of action, such as the copper IUD (e.g., ParaGard), which lasts for 10-12 years, but it's not the only one with such a long duration.
**Option B:** This option is incorrect because it does not specify the type of IUCD and the duration of action.
**Option C:** This option is incorrect because there are other long-acting reversible contraceptive methods, such as implants (e.g., Nexplanon) and injectables (e.g., Depo-Provera), but it's not an IUCD.
**Clinical Pearl / High-Yield Fact**
The LNG-IUS (Mirena) has a dual role as a contraceptive and a therapeutic agent for treating heavy menstrual bleeding and endometriosis, making it a valuable option for patients with these conditions.
**Correct Answer: C.**
