Spontaneous abortion is the most common complication of pregnancy. Several lines of evidence indicate that immunologic effector cells may play a role in the pathogenesis of idiopathic repetitive abortions. Leukocytes form a substantial proportion of stromal cells in decidua and the endometrial granulated lymphocytes (eGL) is the predominant decidual leukocyte population in the first trimester o...

Background/objective: Studies of the decidual leukocyte populations in women suffering from spontaneous early pregnancy loss may provide insight into immunpathological aspects and even cast light on the etiology of recurrent spontaneous abortion.Methods: In order to clarify the immunological role of endometrial leukocytes in repetitive abortion of unknown etiology, a comparative analysis of phe...

background: different studies show that chromosomal balance translocation in the parents can cause recurrent spontaneous abortions. incidence of chromosomal translocation abnormalities in couples with repeated abortions is from 0% to 31%. objective: the purpose of this research was studying the presence or absence of chromosomal abnormalities and heteromorphism in couples with recurrent abortio...

background: approximately 205 million pregnancies occur each year in the worldwide. on the other hand, spontaneous abortion has been reported in 15-20% of all diagnosed pregnancies. the most common cause of spontaneous abortion is chromosomal abnormalities of the embryo. robertsonian translocation carriers specially 21-14 are the most common balanced rearrangement among the carrier couples with...

Background: There are different etiological factors in spontaneous recurrent abortion which are one of the complications in pregnancy. Primary embryo development in uterine tube and oviduct are affected by different factors such as embryotrophic elements. ETF3 as a embryotrophic factor that contains a complex of complement 3 protein and its derivatives specially iC3b, causes embryo trophoblast ...
