ABSTRACT
Objective:
To determine independent factors of pregnancy in the recipient after frozen-thawed embryo transfer (FTET).Methods:
We performed a retrospective study of 431 patients who had undergone embryo transfer after oocyte donation (OD), in vitro fertilization and embryo cryopreservation between April 2009 and December 2018 at our Reproductive Center. Comparison of general data between clinical pregnant group and non-pregnant group; Logistic regression were used to identify independent factors of pregnancy. The ability of independent factors of pregnancy was assessed by receiver operating characteristics (ROC).Results:
â Pregnancy rates were significantly higher in women with more embryos, more high-quality embryos, more transferred embryos and higher basalfollicular stimulation hormone(FSH) (P<0.05). Pregnancy rate of premature ovarian insufficiency (POI) (75.00%) was higher than advanced age (55.83%,P=0.005) and chromosome abnormality (56.86%,P=0.021). â¡Using logistic regression analysis, the POI (OR=2.065, 95%CI=1.026-4.156), basal FSH(OR=1.499, 95%CI=1.072-1.959), high-quality embryos (OR=1.449, 95%CI=1.072-1.959) and transferred embryos (OR=2.583, 95%CI=1.519-4.391)were independent predictors of pregnancy (P<0.05). â¢The ROC curves revealed the cut-off points of basal FSH was 19.28U/L for pregnancy, the areas under the curve of basal FSH was 0.627, 95%CI=0.572-0.680. According basal FSH and age, all patients were further divided into four groups, pregnancy rates were significantly higher in ≤40 years and FSH>19U/L group (P<0.05). We contain pregnancy rates and multiple pregnancy rates of two transferred embryos were higher than one (P<0.01).Conclusions:
This study supports that pregnancy rates of POI was higher than other infertility diagnosis needed OD. Pregnancy rates of two transferred embryos were higher than one, but multiple pregnancy rates was also higher than one.Key words
