In assisted reproduction, poor ovarian response to controlled ovarian stimulation (COS) leads to poor oocyte yield and depends on the genetic background. We compared the expression of key-genes, coding proteins regulating follicular development, between small (<10 mm) and large ovarian follicles (>16 mm), assuming the size as a hallmark of follicle maturation and oocyte fate. Twenty-two patients undergoing COS were enrolled in a fertility clinics. Granulosa cells and folli...
