Concept of a 'therapeutic window' of luteinizing hormone (LH) for successful conception in assisted reproductive technology and ovulation induction has been reviewed in this literature. The separate but complementary roles of follicle stimulating hormone and LH in stimulating folliculogenesis and ovulation are well established. Levels under which low LH concentrations may be equally or suboptimally needed for oocyte quality and subsequent embryonic development competence has been reviewed along with the data related to the high levels of LH promoting follicular atresia.
