Question

Which one of the following is an example of Hormone releasing IUD?

Accepted Answer

Correct Answer: C — LNG 20Step-by-step Solution:Intrauterine devices (IUDs) are classified into three types: (1) Non-medicated IUDs (e.g., Lippes loop), (2) Copper-releasing IUDs (e.g., CuT, Cu7, Multiload 375), and (3) Hormone-releasing IUDs. LNG-20 releases levonorgestrel (a progestin hormone) locally into the uterine cavity, making cervical mucus hostile to sperm, inhibiting sperm motility, and thinning the endometrium. It is the only hormone-releasing IUD among the options.Why other options are incorrect:A (Multiload 375): A copper-releasing IUD (contains 375 mm² of copper wire); not hormone-releasing.B (CuT): A T-shaped copper-releasing IUD; releases copper ions that are spermicidal. Not hormone-releasing.D (Cu 7): A copper-releasing IUD shaped like the number 7. Not hormone-releasing.Key Concept: IUD classification: Non-medicated (Lippes loop), Copper-releasing (CuT, Cu7, Multiload 375), Hormone-releasing (LNG-20, Progestasert). Copper IUDs work by spermicidal action of Cu²⁺ ions; hormone IUDs thicken cervical mucus and suppress endometrium.
