Abstract Objective To explore the influence of the frequency of the repeated cycles of in vitro fertilization and embryo transfer on the clinical outcome of the patients and its causes，to study the related factors of failure of recurrent in vitro fertilization and embryo transfer.Methods 469 caseswho received in vitro fertilization and embryo transfer in the reproductive center of our hospital from January to December in 2015 were selected and divided into the group A　（326 cases）and group B（143 cases）according to the repeat frequency.Group A was repeated cycle 1，while group B was repeated cycle greater than or equal to 2.The age，duration of infertility，HCG thickness of the endometrium，GN dosage，the number of follicles，oocytes and cleavage rate，high quality embryo rate and clinical pregnancy rate was compared between two groups.Results The age and the amount of Gn in group A was less than that group B，with significant difference　（P＜0.05）.The number of follicles，the number of eggs，the clinical pregnancy rate in group A was higher than that oin group B，with significant difference　（P＜0.05）.There was no significant difference in the duration of infertility，HCG thickness of the endometrium between group A and group B（P＞0.05）.There was no significant difference in the oocytes and cleavage rate，high quality embryo rate between the two groups（P＞0.05）.Conclusion In the cycle of different repetition frequency，the difference of age directly affects the clinical outcome，The clinical pregnancy outcome of repeated in vitro fertilization and embryo transfer failure in patientsmay be improved by proper improving the amount of Gn，optimizing the environment and technology of the embryo lab.
