Step-by-Step Solution
Intrauterine Devices (IUDs) are effective contraceptive devices inserted by doctors or expert nurses into the uterus through the vagina. They are classified into three categories: non-medicated IUDs (e.g., Lippes loop), copper-releasing IUDs (e.g., CuT, Cu7, Multiload 375), and hormone-releasing IUDs (e.g., Progestasert, LNG-20). They prevent conception by suppressing sperm motility or inhibiting implantation.
