And types of spontaneous abortion Spontaneous abortion and its types
Abortion is defined as the descent of the contents of the uterus Uterus (Fetus Fetus The placenta PlacentaAnd placental membranes Placental membranes ) Before the growth of the fetus is sufficiently can survive outside the womb. Often occurs abortion during the early stages of pregnancy any during the first three months of pregnancy First trimester May get as well as during the second trimester of pregnancy Second trimester As for abortion that happened at the beginning of the last three months of pregnancy Third trimester Is called late abortion Late abortion It is no different for premature birth where the fetus is alive in both cases (Chamberlain, 1996) . Sources indicate that 10-15% of pregnancies that can be inferred clinically could end in abortion spontaneous (automatic) Spontaneous abortion (Frederickson & Wilkings-Haug, 1997; Chamberlain, 1996) as confirmed by WHO also indicate that 25% of pregnancies that could end in abortion, most especially in the third world countries (Berer, 2000).
There are four main reasons taken into consideration in the evaluation of patients who have a history clinically refers to a spontaneous abortion and infection include Infection The defect in the chromosomesChromosomal abnormalities The levels of some disorder Heromunat Hormones disorder And anatomical changes Anatomic abnormalities , Is that the majority of cases of fetal loss mediated immune disorders include the presence of autoantibodies Autoantibodies Koddad phosphorous lipids Antiphospholipid antibodies (APA) The nuclear antibodies Antinuclear antibodies (ANA) And inadequate antibody AlgalqhBlocking antibodies When the mother and against white blood cell antigens Leukocytes Lab (Chong et al.,1995) Histocompatiblity leukocyte antigens (HLA) . Classified causes of recurrent spontaneous abortionRecurrent spontaneous abortion Immunological mechanisms Immune mechanisms 50% and a chromosomal disorder by 7-50% and the disruption of luteal phase Luteal phase defect By 5-20% and anatomical changes by 5-10% and infections Infections 1% and finally 15% unknown reasons (Chong et al., 1995) . It is important to know that many women who happen to have spontaneous abortions unknown reasons, 60% of them they can have children later and naturally (Stites et al., 1997) , Guerin chances of a successful pregnancy much less than when the causes of abortion immunological events Vtkon by 30% after three abortions and by 25% after four miscarriages and only 5% after five miscarriages, while higher chance of successful pregnancy of 70-85% in the case of treatment Such reasons (Chong et al., 1995) .
I noticed most of the studies that women with repeated three abortions or more commonly to be have an imbalance immunologically or autoimmune disease or hormonal disorders, etc., and that the recurrence of such disorders in women with recurrent spontaneous abortion compared with women with normal pregnancy (Coulam & Hemenway, 1999; Chong et al., 1995; Stray-Pederson, 1948) Were as follows:
