Quizplus · Accepted Answer

The IUD produces changes in the uterus that prevent pregnancy. It thickens cervical mucus, which makes it difficult for sperm to swim and fertilize an egg. It can also cause inflammation in the uterus that makes it difficult for sperm to survive and for an egg to implant if fertilization does occur.
