Abstract:
OBJECTIVETo compare the clinical outcome of 4 protocols of frozen-thawed embryo transfer cycle to select the optimal endometrial preparation method for frozen-thawed embryos transfer.
METHODSA retrospective analysis of the 4 clinical protocols was conducted including natural cycle, down-regulated hormone replacement treatment (HRT) cycle, hMG cycle and natural cycle+hCG in endometrial preparation for 419 frozen-thawed embryos transfer cycle, and the clinical pregnancy rate, implantation rate, early abortion rate, ectopic pregnancy rate , ongoing pregnancy rate and delivery rate were compared between the 4 protocols.
RESULTSThere was no significant difference between the 4 groups with different clinical protocols in age, duration of infertility, reason of infertility, number of embryo transferred and endometrial thickness. The 4 protocols differed little in the implantation rate, clinical pregnancy rate, biochemical pregnancy rate, early abortion rate, ectopic pregnancy rate, ongoing pregnancy rate and delivery rate in the four clinical protocols.
CONCLUSIONThe 4 clinical protocols for frozen-thawed embryos transfer all have favorable clinical outcome, and choice of a specific protocol should be made according to the a comprehensive consideration of the individual conditions of the patient.
