The effect of endometrial morphology on the outcome of IVF-ET

Objective: To explore the effect of different endometrial morphology on the day of hCG administration in long protocol controlled ovarian stimulation on the outcome after IVF-ET. Methods: A retrospective analysis was conducted of 926 IVF-ET cycles,according to the endometrial morphology on the day of hCG administration,cycles were divided into 3 groups. Group A: endometrial morphology A type,406 cycle; Group B: endometrial morphology B type,394 cycle; Group C: endometrial morphology C type,126 cycle; The age、duration of infertility、endometrial thickness、number of oocyte、number of embryos available、number of embryos transferred、dosage of Gn、implantation rate、pregnancy rate were compared among the three groups. Results: The clinical pregnancy rate and implantation rate of group A was statistically higher than those of group B and C( P 0. 05). The duration of Gn of group C was statistically higher than those of group A and B( P 0. 05). There were no significant difference regarding the age、duration of infertility、number of oocyte,et al between the different endometrial morphology. Conclusion: The A type endometrial morphology is ideal for embryos implantation.
