If we want to have a precise definition of abortion, we must say that when the fetus disappears before the twentieth week of pregnancy, abortion is called a miscarriage. Dr. Azam Sadat Mahdavi, surgeon and gynecologist and infertility and Laparoscopy Fellowship, says that about 15% to 20% of pregnancies occur with gennin abortions, about 80% of which occur before the 12th week of pregnancy. The loss of the fetus after the 20th week of pregnancy is called stillbirth. Abortion is permitted in certain circumstances and with the consent of the parent. When the fetus does not have the proper physical condition and does not have a cure for the disease, the doctor prescribes abortion, which is not legally a problem. In some cases, no maternal and fetal illness is threatened, but the mother wants abortions for some reason like unwanted pregnancy. For this, methods are used including medication, curettage, surgery, or suction and intra-amniotic injection. The best time for abortion is the first trimester of pregnancy.
