Spontaneous Abortion and Miscarriage
Spontaneous abortion and Miscarriage, by definition, is death of the fetus. About 20 to 30% of women with confirmed pregnancies bleed during the first 20 weeks of pregnancy; half of these women spontaneously abort. Thus, incidence of spontaneous abortion is up to about 20% in confirmed pregnancies. Incidence in all pregnancies is probably higher because some very early abortions are mistaken for a late menstrual period.
Early spontaneous abortion is often caused by chromosomal abnormalities. Maternal reproductive tract abnormalities (eg, bicorn ate uterus, fibroids, and adhesions) may also cause pregnancy loss through 20 weeks gestation. Isolated spontaneous abortions may result from certain viruses—most notably cytomegalovirus, herpes virus, parvovirus, and rubella virus. Other causes include immunologic abnormalities and major trauma
