Bortoletto P, Romanski PA, Magaoay BI, et al. - Via this retrospective cohort study, researchers sought to investigate if reproductive or neonatal outcomes are influenced by the time from oocyte retrieval to frozen embryo transfer (FET) in the natural cycle. A total of 576 consecutive freeze-all cycles from January 2011 to December 2018 followed by natural cycle FET of a single blastocyst were assessed for primary outcome of live birth and secondary outcomes of preterm delivery (24–37 weeks) and small for gestational age (SGA). Outcomes revealed no statistical impact on odds of live birth or neonatal outcomes in correlation with performing a natural cycle FET of a single blastocyst in the second compared with the first menstrual cycle after ovarian stimulation.
