ABSTRACT

Objective To evaluate the influence of pregnancy outcomes with different dosage of estradiol valerate in addition to progesterone for luteal supplementation in IVF-ET cycles. Methods From February 2011 to October 2012, 362 patients undergoing IVF-ET in the second affiliated hospital of Kunming Medical University were selected. The patients were randomly assigned into three groups. Since oocyte retrieval, all of them were injected luteal supplementation with progesterone in oil 60 mg/d, im. Group A as control group (112 cases) did not add with pentanoic acid estradiol;Group B for the experimental group (122 cases), added pentanoic acid estradiol 4 mg/d after embryo transfer;Group C for the experimental group (128 cases) added pentanoic acid estradiol 6 mg/d after embryo transfer. Finally the pregnancy outcome and implantation rate were compared for each group. Results There were no significant differences between group A and group B, group B and group C in the rate of embryos grow and pregnancy rate ( >0.05) . The embryo planting rate and pregnancy rate have significant difference between Group A and group C ( < 0.05) . Conclusion 6 mg/d fill estradiol valerate for luteal supplementation may improve implantation rate and pregnancy rate after IVF.
