Objective: To evaluate the impact of preimplantation genetic testing for aneuploidy (PGT-A) on first transfer live birth rate (LBR) and cumulative LBR (CLBR) in donor oocyte in vitro fertilization (IVF) cycles.
Design: Retrospective cohort study of the Society for Assisted Reproductive Technology Clinic Outcome Reporting System database.
Setting: Fertility centers reporting to Society for Assisted Reproductive Technology.
Purpose: Multifetal gestation (MFG) is much more common in pregnancies that utilize assisted reproductive technologies (ART). We assessed how these rates have changed over the previous decade and the impact on live birth rates (LBR).
Methods: This retrospective cohort study uses the National Summary Reports of the Society for Assisted Reproductive Technology (SART) from 2014 to 2020.
Strawberry or red leopards are a rare colour morph of leopard () characterised by spot markings that are red or brown instead of black, thought to be a result of a mutation in the tyrosinase-related protein (TYRP1) gene.
