Molecular evaluation of endometrial receptivity in women with congenital malformations of genital tract

Background: Uterine congenital malformations (UCM) occur in 3-4% of women overall, in 4% of infertile women and in 15% of those who have experienced recurrent miscarriage. Uterine malformations consist of a group of miscellaneous congenital anomalies of the female genital system. Their mean prevalence in the general population and in the population of fertile women is ∼4.3%, in infertile patients ∼3.5% and in patients with recurrent pregnancy losses ∼13%. Septate uterus is the commonest uterine anomaly with a mean incidence of ∼35% followed by bicornuate uterus (∼25%) and arcuate uterus (∼20%). To present the potential clinical impact which uterine congenital malformations (UCM) may exert on human embryonic implantation and discuss in receptive endometrium genes.Objective: In this study, differences in gene expression between UCM and normal endometrium were evaluated using a PCR Array approach.Materials and Methods: The mRNA of endometrium was analyzed in 3 groups (septet uterus, unicorn uterus, normal uterus, n=15). The differentially expressed genes of receptivity endometrium pathway were analyzed.Results: The mRNA levels of expression in EGF, CSF, HOXA10, HOXA11, LIF, LIFR, MUC1 were all significantly higher in the unicorn group compared to control (p<0.05) but EGF, CSF, HOXA10, HOXA11, LIFR, MUC1 were all significantly lower in the septate group compared to control (p<0.05). However, LIF was expressed higher in septate group compared to control (p<0.05).Conclusion: This investigation showed that the patients with UCM have different pattern of endometrial receptivity. Further research should be done to clarify the endometrial receptivity in different type of uterine anomaly.
