Question:
Complete the following analogy:
Cu-T : Suppress sperm motility
LNG-20 : ___________
Complete the following analogy:
Cu-T : Suppress sperm motility
LNG-20 : ___________
Cu-T : Suppress sperm motility
LNG-20 : ___________
Show Hint
LNG-20 is a hormone-releasing IUD that makes the cervix hostile to sperm.
Updated On: Nov 12, 2026
- Phagocytosis of sperms
- Makes cervix hostile to the sperm
- Inhibition of ovulation
- Alters the quality of cervical mucus
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
In the analogy, each device is paired with its mode of action.
Step 2: Cu-T
It releases copper ions that suppress sperm motility and fertilising ability.
Step 3: LNG-20
It is a hormone-releasing IUD with levonorgestrel. It makes the cervix hostile to sperm and makes the uterus unsuitable for implantation.
Final Answer:
LNG-20 makes the cervix hostile to sperm. \[ \boxed{\text{(B) }\text{Makes cervix hostile to the sperm}} \]
