W. Heisenberger, I will discuss how mammalian spermatozoa prepare themselves for fertilization and how the spermatozoa and eggs interact during fertilization. The process and mechanisms of sperm transport in the female genital tract will not be dealt with extensively here. Readers are referred to Bishop (1961, 1

K. Symanzik reaction and granule exocytosis are of primary interest to any discussion of polyspermy for cortical granule contents have been associated with polyspermy-preventing mechanisms in the eggs of animals of diverse species (for review, see Schuel, 1978, or Gulyas, 1980).

chronology

K. Gottsteinapse, the synaptonemal complex (SC; see below) is formed and reciprocal recombination — crossing over — takes place. At metaphase I, the paired chromosomes have formed bivalents that are held together at the chiasmata (the points of cross overs), and disjoin at anaphase I. After a short interphase,

LASH

M. Deutschmann,P. Meyer and molecular biology technologies have ensured that the gap has diminished in recent years (e. g. see chapters by Colombo, Kranz; Dumas et al. 1998; Huang et al. 1992; Wagner . 1990). While all plants show the alternation of haploid and diploid generations, the organisms resulting from the gametop

K. Wirtzincreased, but still many ques- tions remain to be answered. Being aware of the necessity of providing an inte- grated view of the process of fertilization, this book has been entirely devoted to reviewing the process of oocyte fertilization at the cellular/molecular level in two different and separ
