The objective is to know the effect of these regenerative factors obtained from Platelet-Rich Plasma in an immunodeficient murine model with AS/EA Blood from patients with Asherman's Syndrome (AS) and Endometrial Atrophy (EA) will be collected, maintained under anticoagulant solution and after several centrifugations PRP will be obtained. Demonstration of a functional endometrium will be proved determining pregnancy and implantation rates as well as the number of live pups/pregnant female in our mice model. Also, the uterus histology will be analysed in treated and untreated mice
