Placental trophotropism

Dr Jeremy Jones and Radswiki et al.

Placental trophotropism refers to a phenomenon where there is dynamic migration of the placenta at its insertion through gestation. The placenta tends to grow in areas of good blood supply and nutrition and artophies in areas with poor blood supply and poor nutrition. It may play a role in development of abnormal placental shapes - see variation in placental morphology.

Placental trophotropism is the reason why placenta previa noted in an early pregnancy scan may resolve in a later scan. The placenta moves at approximately 1 mm per week 3.
