Abstract:
Objective To analyze the influential factors of clinical pregnancy rate of the frozen-thawed embryo transplantation. Methods The data of 3 192 FET patients in the reproductive medicine center of our hospital up to May 2014 were analyzed retrospectively. According to ages, reasons of infertility, types of infertility, duration of infertility, drug regimen, the number and the time of embryo transplantation, we divided these patients into six groups for comparing the clinical pregnancy rate. Results The FET clinical pregnancy rate of the under 35 years group was higher than the 35~39 years group and the over 39 years group (33.96%vs. 27.58%and 19.35%; P<0.05, respectively). The duration of infertility in the clinical pregnancy group was significantly shorter than the non-pregnancy group (P<0.05). The clinical pregnancy rate in the group with three embryos transplanted was higher than the group with only two embryos transplanted (41.01% vs. 28.75%; P < 0.05). Among the group with the age of over 40 years, those with three embryos transplanted had a higher clinical pregnancy rate than those with only one embryo transplanted (25.49% vs. 0.00%; P < 0.05). The clinical pregnancy rate of the frozen blastocyst transplantation group was higher than that of the cleavage-stage transplantation group (40.00%vs. 26.27%;P<0.05). Conclusion Age, infertility duration, the number and the time of frozen embryo transplantation may affect the clinical pregnancy rate among the FET patients. An individualized transplantation program based on age may improve the patient′s clinical pregnancy rate.
