Human leukocyte antigen G (HLA-G) is thought to play a key role in implantation by modulating cytokine secretion to control trophopblastic cell invasion and to maintain a local immunotolerance.The literature is reviewed to provide a description of th

Problem: Implantation determines success of in vitro fertilization (IVF) and embryo transfer (ET) cycles. Data are accumulating to support a role of the immune system in implantation. Most of the literature addresses the importance of natural killer
