A medical termination of pregnancy (MTP) or abortion is a type of non-surgical abortion in which pharmaceutical drugs are used to induce abortion. An oral preparation for medical abortion is commonly referred to as an abortion pill. Medication abortion regimens can be safely and effectively used throughout the first 49 days of pregnancy. The copper IUD is the most effective form of emergency contraception. Copper IUDs actually prevent fertilization by reducing the number and viability of sperm reaching the egg, and by impeding the number and movement of eggs into the uterus.
