The IUC (Intrauterine Contraceptive) works by preventing fertilization in several ways. It thickens the cervical mucus, making it harder for sperm to reach the egg. It also affects the movement of the sperm, preventing them from reaching the egg. In some cases, it can also make the lining of the uterus thinner and inhospitable to fertilization.
