Differential proteomic analysis of endometrial fluid suggests increased inflammation and impaired glucose metabolism in non-implantative IVF cycles and pinpoints PYGB as a putative implantation marker

Is there any difference in the protein composition of the endometrial fluid aspirate (EFA) obtained the day of embryo transfer in in vitro fertilization (IVF) cycles achieving and not achieving pregnancy?Comparative analysis identified a differential protein expression pattern in 'implantative' and 'non-implantative' IVF cycles.EFA allows non-invasive characterization of the endometrium, and may contain important information on its receptivity...
