Background: Poor ovarian response is defined as the collection of three or fewer oocytes in two prior ovarian stimulation cycles, or collection of three or fewer oocytes in a single stimulation cycle from a woman who is over 40 years of age, or collection of three or fewer oocytes in a single stimulation cycle and an abnormal ovarian reserve test. We aimed to determine if in poor responders’ patients, the SAS stimulation protocol allows for a better number of oocytes, mature oocytes, total embryos at D2 and usable embryos in comparison with the last previous IVF attempt within the same patients
