ECTOPIC PREGNANCY, MISCARRIAGE
A total of 129 patients who met the inclusion criteria were enrolled (59 in the intervention group and 70 in the control group). The baseline clinical characteristics of the two study groups are shown in Baseline clinical characteristics of females and embryos at the time of artificial cycle frozen embryo transfer.Values are mean ± SD unless stated otherwise.BMI: body mass index; FET: frozen embryo transfer.A slightly higher β-hCG level and increased implantation rate were observed in the intervention group comparing to the controls, although the differences were not statistically significant. There was a higher rate of positive pregnancy tests in the intervention group than the rate of the control group (57.6% vs 42.9%). Correspondently, the clinical pregnancy rate was 9.2 percentage points higher in the intervention group comparing to the controls (49.2% and 40.0%); Females in the intervention group had a 12.1 percentile higher live birth rate (LBR) versus the control group (40.7% vs 28.6%). Correspondently, the miscarriage rate was 14.7 percentage points lower (10.3% vs 25%). The differences were notable in the clinic although no statistical significance was concluded. From the intervention group, 59 females gave birth to 30, while only 21 births were counted in 70 females in the control group. The number of macrosomia in both the intervention group and the control group is similar. No difference was observed in the numbers of chemical pregnancy, the ectopic pregnancy, and the twining pregnancy between the two groups (Clinical outcomes of artificial cycle frozen embryo transfers receiving standard hormonal substitution and additional single dose triptorelin acetate for luteal support.
