Chong Lin,Qing-Guo Wang,Yong HeThe ever-increasing world-wide use of the IUD has prompted intensive research into the physiology of its contraceptive action. From these studies it has become clear that the alterations in morphology as well as in the physiological milieu produced by the IUD are manifold and differ greatly with the type of IUD used.
