Question

Which among the following IUD makes uterus unsuitable for implantation?

• A. Multiload 375
• B. Lippes loop
• C. LNG-20
• D. Cu7

Answer 1

The correct option is C LNG-20

Hormone releasing IUD's make uterus unsuitble for implantation. LNG-20 is hormone releasing IUD.

Multiload 375 and Cu 7 are copper releasing IUD's. Cu ions suppress sperm motility and fertilising capacity of sperms. Lippes loop also prevent sperm movement towards the fallopian tube.
