Question

Select the hormone-releasing Intra-Uterine Devices.

• A. Vaults, LNG-20
• B. Multiload 375, Progestasert
• C. Progestasert, LNG-20
• D. Lippes Loop, Multiload 375

Answer 1

The Correct Option is C

The question asks us to identify the hormone-releasing Intra-Uterine Devices (IUDs) from the given options. Let's analyze each option to find the correct answer.

1. Progestasert: Progestasert is an IUD that releases progesterone hormone into the uterus. It is designed to provide birth control by thickening the cervical mucus and inhibiting sperm penetration.
2. LNG-20: LNG-20 is another type of IUD that releases the hormone levonorgestrel. It works similarly by maintaining a thick cervical mucus, thereby preventing sperm from entering the uterus and fertilizing an egg.
3. Multiload 375: This is a non-hormonal IUD. It functions by physically preventing sperm from meeting an egg and usually contains copper, which acts as a spermicide.
4. Vaults: This appears to be a typographical error or a misnomer in the option list. There is no known IUD by this name that is recognized for hormone release.
5. Lippes Loop: Like Multiload 375, Lippes Loop is a non-hormonal IUD made of plastic or metal, shaped like a double 'S', relying on its physical presence to prevent pregnancy.

From the analysis above, Progestasert and LNG-20 are the only IUDs listed that release hormones. Therefore, the correct answer is Progestasert, LNG-20.
