Can ovarian double-stimulation in the same menstrual cycle improve IVF outcomes?

Objective: To evaluate the double-stimulation protocol efficacy over conventional ovarian stimulation in recovering a more adequate number of oocytes and increase the number of embryos to be transferred or to be genetically analyzed.
