Abstract
During oogenesis the oocyte is arrested in meiosis twice. First at prophase I, then a second time at metaphase I in many invertebrates and in metaphas e II in the vast majority of vertebrates. Meiosis resumption is triggered b y the sperm. This article examines mechanisms that cause oocytes' at-rest i n meiosis and how spermatozoa help the oocyte to get out of this cellular p redicament.
