We will investigate maternal and embryonic factors in women with recurrent implantation failure, undergoing IVF/ ICSI treatment. Women who have not achieved a pregnancy after three embryo transfer procedures will undergo an endometrial biopsy during the window of implantation in a natural cycle. During the next treatment cycle we will aspirate endometrial secretion and perform a doppler ultrasound investigation of the a. uterina. Moreover, we will investigate the cytokine expression from the transferred embryo from the culture medium.
