Recurrent miscarriage and factors that effects its: A review

Abstract

Spontaneous abortion is a commonly occurring issue during human pregnancy. The definition provided by the WHO in 1977 is universally accepted. Recurrent pregnancy loss is a multifaceted health issue that lacks a universally agreed-upon definition. The lack of agreement in definitions encompasses not only the varying number of spontaneous abortions (two or three) that are considered recurrent pregnancy losses but also the different types of pregnancies and the gestational age at which the miscarriage occurs. The prevalence among clinical pregnancies is approximately less 15%, but when early pregnancy losses are included, it rises to 17–22%. The only two etiologic causes that all authors agree on are uterine abnormalities and paternal balanced chromosomal rearrangements. Numerous alternative risk variables have been proposed.
