In IUGR pregnancies, reductions in fetal growth are associated with reduced fetal cord serum levels of IGF‐1 (Nieto‐Díaz et al. 1996; Klauwer et al. 2011), which reflect compensation for the altered substrate (Halhali et al. 2000) and oxygen supply (Dinleyici et al. 2006). Here, IGF1 is linked to fetal growth restriction.
