Methods We selected 464 elderly women with normal ovulation who came to the First Affiliated Hospital of Xi’an Jiaotong University from January 2016 to July 2017 as study group. Another 436 women aged less than 35 years old who planned pregnancy in the same period were selected as control group. The clinical data were compared between the two groups. Results There was no significant difference in average diameter of dominant follicles and endometrial thickness at each monitoring point between the two groups (P>0.05). There was no significant difference in corpus luteum blood flow grade 1 day after ovulation (P>0.05), but corpus luteum blood flow grade 7 to 9 days after ovulation in study group was significantly reduced as compared with control group (P<0.05). The two groups did not differ significantly in corpus luteum volume (V) or vascular parameters 1 day after ovulation, corpus luteum V 7-9 days after ovulation (P>0.05). However, luteum vascularization index (VI), flow index (FI) and vascularization flow index (VFI) significantly decreased in study group compared with control group (P<0.05). Biochemical pregnancy rate and clinical pregnancy rate were 16.38% and 9.05% in study group, which were significantly lower than 23.17% and 19.04% in control group, respectively (P<0.05). Miscarriage rate of biochemical pregnancy in study group was 7.33%, significantly higher than 4.13% in control group (P<0.05). Corpus luteum V and vascular parameters in women with biochemical pregnancy abortion in both groups were significantly lower than those with clinical pregnancy (P<0.05). Conclusion The decreased of blood supply of the corpus luteum in embryo implantation window of elderly women may be related to the reduction of endometrial receptivity and pregnancy rate.
