Objective To analyze the effect of the numbers of transferred good-quality embryos on pregnancy outcomes in in vitro fertilization-embryo transfer （IVF-ET）, supplying a reference for selection of transferred embryos.Methods Five hundreds and one infertile patients who underwent IVF-ET were retrospectively analyzed. All cycles were divided into 3 groups by the number of transferred good-quality embryos （group A： two good-quality embryos, group B： one good-quality embryo, group C： no good-quality embryo）, with no significant difference in general condition such as age, infertility duration and infertility types. The pregnancy outcomes were compared and analyzed among the three groups.Results 1） Live-birth rate was improved with increasing good-quality transferred embryo numbers. Groups A （70.3%） and B （69.8%） had no significant difference （P=0. 409）, whereas it was significantly greater in groups A and B than in group C （57. 7%）（P=0.009, P=0.036）. 2） The loss of single gestational sacs rate, which have no significant difference among 3 groups （P=0.221, P=0.539, P=0.226）, reduced with increasing good-quality transferred embryos numbers. 3） Biochemical pregnancy abortion rate in groups A （10.9%） and B （10.1%） was significantly lower than that in group C （18.3%）（P=0.049, P=0.049）. 4） There was no significant difference among 3 groups in ectopic pregnancy rate （P=0.174, P=0.129, P=0.404）. 5）multiple-birth rate was improved with increasing good-quality transferred embryos numbers, it was significantly greater in group A （31.6%） than in group C （15.0%）（P=0.020）, while groups B and A had no significant difference （P=0.489, P=0.126）.Conclusion Two good-quality transferred embryos have no significantly difference to 1 good-quality embryo in all pregnancy outcomes. In clinic treatment, we can select 1 good-quality embryo and 1 poor-quality embryo when patients only have few goodquality embryos. Meanwhile, a good-quality embryo can improve live-birth rate and multiple pre

A Delayed-interval Delivery of An in vitro-fertilized Twin Pregnancy with Premature Rupture of Membranes

This article presents a case of conservative managements of an in vitro-fertilized twin pregnancy with early loss of the first fetus. A 37-year-old woman in the 21st week of a twin pregnancy delivered her one of the fetuses with unfortunate outcome after the premature rupture of membranes. The umbilical cord of the first fetus was ligated at the cervical level and the second surviving fetus was left in utero. In order to save the surviving fetus, conservative managements including combination of steroids, tocolytics, antibiotics and cervical cerclage were performed. The second fetus was delivered vaginally in the 27th week of pregnancy, 4 h after premature rupture of membranes of the remaining amniotic sac, 41 d after the first fetus was born. The child and the mother have been followed up for 4 years and they are healthy. Conservative managements including steroids, tocolytics, antibiotics and cervical cerclage in a closely monitored environment would be given following the delivery of the first fetus. Delayed-interval pregnancy appears to be safe for the mother and the remaining fetuses.
