What determines umbilical cord length?

The length of an umbilical cord is thought to be determined in part by how much the baby moves around in the womb; fetal activity pulls on the cord and stretches it out. Cord length may also be influenced by different protein expression patterns of genes involved in cell proliferation (1).

At what length umbilical cord is cut?

The umbilical cord is clamped and cut off at a distance of 2-3 cm from the newborn’s abdominal wall after birth, after which its function is terminated. The necrotic tissue remaining in the newborn’s umbilical cord provides an ideal environment for bacterial growth.
