Q66 / 200 · MHT CET - Medical 2026 (23 April Shift 2) · Biology
Identify correct function of following IUDs:
- Correct answerALippes loop - It attracts the macrophages stimulating them to accumulate in the uterine cavity.
- BCu-T - It delays pregnancy for longer period.
- CCu 7 - Makes the uterus unsuitable for implantation.
- DLNG-20 - Suppresses sperm motility
Solution
Lippes loop is a non-medicated IUD. It induces a mild inflammatory response in the endometrium, which attracts macrophages and stimulates them to accumulate in the uterine cavity, thereby increasing the phagocytosis of sperms.
Cu-T and Cu 7 are copper-releasing IUDs. The released copper ions suppress sperm motility and the fertilising capacity of sperms.
LNG-20 is a hormone-releasing IUD. It makes the uterus unsuitable for implantation and the cervix hostile to sperms.
