title: Sex determination: time for meiosis? The gonad decides.
abstract: Germ cell sex determination is directed by the gonad and is characterized by a difference in the timing of entry into meiosis. Recent data show that retinoic acid signalling is responsible for the induction of germ cell meiosis in the developing ovary. In the fetal testis, this process is inhibited by a retinoic acid metabolizing enzyme.
