Send us Fan Mail Ben and Daphna dig into a large, population-based study linking IVF conception to VACTERL association, a rare but serious pattern of congenital anomalies spanning the vertebral, anal, cardiac, tracheoesophageal, renal, and limb systems. Drawing on over 1.5 million births across four US states and linked SART registry data, the study finds IVF-conceived infants face significantly higher odds of VACTERL and related multiple anomaly syndromes compared to naturally conceived infants. Daphna and Ben unpack what this means for clinical suspicion at the bedside, why some VACTERL phenotypes may be easy to miss, and how better tracking of conception history through delivery could change how NICU teams approach anomaly workups in IVF-conceived infants. ---- In Vitro Fertilization and VACTERL Birth Defects.
