This is a study designed to validate Kawamura´s theory and investigation of activation of primordial follicles through ovarian cortex fragmentation. Our aim is to evaluate embryo quality following this procedure in poor ovarian responders and patients with decreased ovarian reserve. Secondary objectives are to assess potential association with the number of oocytes retrieved and pregnancy rates after IVF.
