How soon can I have sex after IUD insertion?

Dear Ask The Doctor: I recently had the flexi t 380 IUD inserted one week ago and was wondering how long after do you have to wait to have sexual intercourse?

Dear Krystle: IUD or intrauterine device is a T-shaped device that is inserted into the uterus to prevent pregnancy. IUDs prevent the sperm travelling to the egg, thus preventing pregnancy. You can have sex as soon as you like after the IUD is inserted.
