Question

The intra uterine devices (IUDs) that make uterus unsuitable for implantation and cervix hostile to sperms are:

• A. LNG 20, Multiload 375
• B. CuT, Cu7
• C. Progestasert, lippes loop
• D. Progestasert, LNG 20

Hint:

Remember the key functions associated with hormone-releasing IUDs: they are the only ones that make the cervix hostile and the endometrium unsuitable.
Copper-releasing IUDs, on the other hand, focus primarily on suppressing sperm motility and fertilization.

Answer 1

The Correct Option is D

Step 1: Group IUDs by their working principle.
Non-medicated devices like the Lippes loop work purely mechanically. Copper releasing devices such as CuT and Cu7 rely on copper ions that are toxic to sperm. Hormone releasing devices slowly leak progesterone into the uterus.
Step 2: Match the described action to a group.
The question describes an endometrium turned hostile to implantation plus cervical mucus turned hostile to sperm, this dual local hormonal effect is the signature of progesterone releasing devices, not copper or mechanical ones.
Step 3: Pick the correct pair from that group.
Progestasert and LNG 20 are the two well known hormone releasing IUDs that produce exactly this effect.
Final answer: Option 4, Progestasert and LNG 20.
