Clinical Analysis on Frozen Thawed Embryo Transfer Cycle in 138 Cases

Objective To compare the clinical outcome of 3 protocols of frozen-thawed embryo transfer cycle to select the optional endometrial preparation method for frozen-thawed transfer. Methods To retrospectively analyze the natural and HRT rotocols in endometrial preparation for 138 frozen-thawed embryos transfer cycle.A retrospective analysis of the 3 clinical protocols was conducted including natural cycle,hormone replacement treatment cycle,HMG cycle,and the clinical pregnancy rate,implantation rate,early abortion rate,ongoing pregnancy rate were comprared arnong 3 protocols. Results There was no significant difference arnong 3 groups with different clinical protocols in age,duration of infertility,reason of infertility,number of embryo transfer and endometrial thickness,pregnancy rate,implantation rate,quality of embryo transfer.There was no significant difference in endometrial thickness.The 3 protocols differed little in the implantation rate,clinital pregnancy rate,biochemical pregnancy rate,early abortion rate,ongoing pregnancy rate in the three clinical protocols. Conclusion The 3 clinical protocols for frozen-thawed embryos transfer all have favorable clinical outcome,and choice of a specific protocol should be made according to the comprehensive consideration of the individual conditions of each patient.
