To determine whether elective single embryo transfer (eSET) reduces the risk of preterm delivery associated with in vitro fertilization (IVF).
This is an observational study of 3125 eSET cycles performed from 2008 to 2009 and reported to the Society for Assisted Reproductive Technology (SART) database. Preterm delivery rates were compared to the overall preterm delivery rate among all patients undergoing IVF over the same time period.
The 3125 eSET cycles resulted in 1507 live births (live birth rate 48.2 %) Among these deliveries were 27 twins (1.8 %) and one set of triplets (0.07 %). The overall preterm delivery rate (20-37 weeks gestation) following eSET was 17.6 % (269/1527). This is significantly greater than the preterm birth rate for all patients undergoing IVF over the same time period (12 %, P < 0.001).
Elective single embryo transfer does not reduce the risk of preterm delivery associated with in vitro fertilization (IVF).
确定选择性单胚胎移植(eSET)是否能降低与体外受精(IVF)相关的早产风险。
这是一项对2008年至2009年进行的3125个eSET周期的观察性研究,并报告给辅助生殖技术协会(SART)数据库。将早产率与同期所有接受IVF的患者的总体早产率进行比较。
3125个eSET周期产生了1507例活产(活产率48.2%)。在这些分娩中,有27对双胞胎(1.8%)和一组三胞胎(0.07%)。eSET后的总体早产率(妊娠20 - 37周)为17.6%(269/1527)。这显著高于同期所有接受IVF的患者的早产率(12%,P < 0.001)。
