Abstract:
Objective To investigate the influence of ovarian arterial blood flow index on pregnancy outcomes in patients undergoing in vitro fertilization and embryo transfer (IVF-ET).Methods Totally 136 infertile patients undergoing IVF-ET from February 2014 to April 2016 were divided into pregnant group and non-pregnant group.The monitoring through transvaginal B of two groups for chorionic gonadotropin (HCG) day and ovarian artery resistance index (RI),pulsatility index (PI) and umbilical artery diastolic flow velocity height ratio (S/D) on 2nd day of menstruation (M2) was conducted.The difference of blood flow indexes in two groups was analyzed.Results Compared with those in non-pregnant group,RI,PI and S/D in pregnant group were decreased on M2,and the difference was statistically significant (P ＜ 0.05).RI and PI were also decreased significantly on HCG day,and the difference was statistically significant (P ＜ 0.05),but S/D showed no significant changes (P ＞ 0.05).RI and PI decreased significantly on HCG day in two groups (P ＜ 0.05) when compared with those on M2,but in non-pregnant group,the comparison of S/D on HCG day showed no statistical significance (P ＞ 0.05).Conclusions There is close relationship among RI and PI of ovarian artery and ovarian reserve function.RI and PI are effective indexes to predict outcomes in IVF-ET,and provide scientific basis for the preparation and treatment for IVF-ET.
