Miscarriage Miscarriage A miscarriage, also called spontaneous abortion, is usually hard to deal with. It is accidental or natural ending of a pregnancy before a developing baby can live outside its mother’s body. Couples usually blame themselves for what has happened and it is really not their fault. It occurs in 15-20 percent of all pregnancies, usually in the frist three months. Early miscarriages are due to chromosomal division errors or that the uterus, the organ in which the offspring develops, cannot with stand the pressure of the growing fetus (Miscarriage, online). According to The World Book Encyclopedia “up to 60 percent of all miscarriages occur because of defects in the embryo’s chromosomes. In most miscarriages involving defective chromosomes, the embryo cannot develop normally. A miscarriage may also occur if progesterone, a hormone necessary to maintain pregnancy, is in sufficient amount” (p. 508). According to The World Book Encyclopedia “studies indicate that 15 to 20 percent of all diagnosed pregnancies end in miscarriage. The risk of miscarriage is highest during the first three months following conception (fertilization), during which time many women do not know they are pregnant. miscarriage, pregnancy, abortion, miscarriages, pregnancies, percent, breast, bleeding, women, september, retrieved, online, first, causes, 2004, world, three, risk, occur, encyclopedia, during, cramping, cancer, before, woman, one, normally, early, due, coffee, after, weeks, pregnant, months, healthy
