Practice patterns and outcomes with the use of single embryo transfer in the United States

Cumulative Birth Rates With Linked Assisted Reproductive Technology Cycles

“…5 Although the highest live-birth rates for both autologous and donor oocytes were achieved when two embryos were transferred, this also increased the possibility of a multiple birth. 19 The transfer of more embryos to obtain higher live-birth rates needs to be balanced against the increased risk of a multiple gestation and associated risks when more than one embryo is transferred.…”

Embryo quality is the main factor affecting cumulative live birth rate after elective single embryo transfer in fresh stimulation cycles

“…Currently, eSET is more commonly applied to women younger than 36 years [1]. eSET has been suggested as a treatment of choice in this age group, even in countries with low eSET use [12,15].…”

Influence of infertility diagnosis on pregnancy outcome in ART

“…7 This is significantly greater than the national average reported in a survey of the SART database showing a rate of only 4-5% SET between the years 2004 and 2006. 8 The presence of a second gestational sac that spontaneously disappears after eight weeks gestation has been associated with poorer obstetrical outcomes in several previous studies, including preterm delivery, low birth weight, very low birth weight, and postnatal mortality in survivor singleton pregnancies .9,10 Further subgroup analysis within our cohort was considered, but was not performed because of the very small number of women with a vanishing twin.…”
