The crosstalk between a receptive endometrium and a functional blastocyst during human embryo implantation is crucial for conception. Because platelets rich plasma (PRP) with concentrated platelets 4-5 times higher than normal, when release of granules containing growth factors including VEGF, TGF, PDGF, IGF, and EGF, these factors involved for sub endometrial angiogenesis and endometrial receptivity. 44 women under the age of 40 were given antagonist ovarian stimulation treatments, the oocytes were harvested utilizing 2-D power doppler ultrasound guidance, then ICSI done for them. On the hCG day all had an intrauterine autologous PRP infusion. Power Doppler is utilized to measure endometrial thickness (EnT), pulsatility index (PI), and resistance index (RI) of sub endometrial arteries, as well as serum levels of VEGF and EGF were measured on the hCG day and ovum pickup (OPU). The ultrasound findings, on the hCG day compared to those of OPU in all women with intrauterine infused autologous PRP were highly significant (HS). The mean EnT, RI, PI, VEGF and EGF at OPU day was lower than that on hCG day in a HS manner, with (p < 0.001), (p < 0.001), (p=0.047), (p < 0.001), and (p<0.001) respectively. These characteristics were shown to be significantly and independently associated to intrauterine PRP infusion. After PRP injection, both growth factors serum levels (VEGF and EGF) increased, and ultrasonography sub-endometrial metrics such as EnT, RI, and PI changed as the thickness grew while vascular resistance decreased, and all considered as predictors of
