Copper ions-releasing IUDs are more efficient than non-medicated methods. Why?
Answers (1)
Ans. Phagocytosis of sperm is initiated because of IUDs, hence preventing conception. Lippes loop (non-medicated IUDs) work on this concept. Whereas copper-releasing IUDs provide added benefits over the effects of normal IUDs; copper is known for suppressing sperm motility. And therefore, sperms are unable to reach the fallopian tube. Some sperms can reach the fallopian tube in case of normal IUDs. This will result in failure rates of IUDs. Thus, copper releasing IUDs are superior to normal IUDs, and they are more efficient.
