[Current findings on the endometrium and human reproduction]

Human endometrium is a very complex system that plays a critical role during implantation process. Several reports focused the attention on the adequate proliferative phase, particularly on mitotic and angiogenetic pathway. The growth factors and angiogenetic factors involved during the different phases of menstrual cycle are discussed and attention is drawn on the interaction between embryo and endometrium through metalloproteinases and integrins during implantation.
