Abstract		This study compared serum and follicular anti-mullerian hormone, LH, FSH, E(2), and P concentrations in modified natural cycles and controlled ovarian hyperstimulation cycles to analyze their effect on oocyte and embryo quality and implantation. Follicular anti-mullerian hormone, FSH, E(2), and P concentrations had no effect on embryo quality, whereas high serum and follicular LH concentrations in natural cycles modified only with hCG did not compromise oocyte and embryo quality but might have a negative effect on implantation.
