N number, PB polar body, IVM in vitro maturation; analyzed oocytes: oocytes obtained from gonadotropin-stimulated cycles that were analyzed by fluorescence microscopy after observation of the first PB extrusion after IVM; non-analyzable Metaphase II: oocytes fixed with spindles in a polar view; p value obtained by Fisher’s exact test
