Question
Bring out one main difference between $CuT$ and $LNG–20$.
✓
Answer
$CuT$ is copper releasing $IUDs$ and $LNG–20$ is hormone releasing $IUDs$.
$Cu^{2+}$ ions released suppress sperm motility and thus the fertilising capacity of sperms decreases.
While the hormone releasing $IUDs$ make the uterus unsuitable for implantation and the cervix hostile to the sperms.
