Not usually: The main way that paragard prevents pregnancy is by thickening the cervical mucus, to prevent sperm from passing through the cervix, but it also has an effect of causing inflammation in the uterus that can be 'toxic' to sperm that do make it into the uterus, and it does have a small chance of causing abortions, if a sperm makes it past both of those hazards.

No: The Paragard IUD can act as emergency contraception if inserted within 5 days of unprotected intercourse. It is a very effective form of contraception.
