Which of the following IUCD last for 10 years :
**Core Concept**
The question requires knowledge of Intrauterine Contraceptive Devices (IUCDs), specifically their duration of action. IUCDs are a type of long-acting reversible contraceptive method that releases hormones or copper to prevent pregnancy.
**Why the Correct Answer is Right**
The 10-year IUCD is a type of hormone-releasing IUCD, specifically Mirena (levonorgestrel-releasing intrauterine system). It works by releasing a small amount of the progestin hormone, levonorgestrel, which thickens cervical mucus, thins the uterine lining, and prevents ovulation. This hormone is released at a controlled rate, allowing the IUCD to provide effective contraception for up to 10 years.
