The acrosome of eutherian mammals
Cell and Tissue Research, 2015The acrosome is not just a bag of enzymes, most of which, if not all, are singly non-essential for sperm-oocyte interaction. The Golgi-derived acrosomal cap reveals some extraordinary development and structure particularities. The acrosome of eutherian spermatozoa basically consists of two parts, the anterior and equatorial segments; the present review

[Acrosome reaction and fertilization].
Contraception, fertilite, sexualite (1992), 1994The acrosome reaction that occurs after sperm capacitation, is an exocytotic event induced by a Ca++ influx. It plays an essential role during fertilization, by making spermatozoa able of penetrating the zona and capable of fusing with the egg plasma membrane. Zona pellucida is the natural inducer of the acrosome reaction. Binding of the sperm receptor

No morphological change has been observed in mouse (Bryan, 1974) or rabbit (Bedford, 1969) spermatozoa lying free in the ampulla of the oviduct. However, as the spermatozoa pass through the cumulus oophorus the outer acrosomal membrane may invaginate to form membrane-bound vesicles within the acrosome followed by loss of the plasma membrane (Jones ...

Publisher Summary The reaction of the acrosome holds a general significance in connection with the fertilization process. This chapter discusses the structural aspects of the acrosome reaction including groups of Echinoidea, Asteroidea, Holothuroidea, Ophiuroidea, and Mollusca—Pelecypoda, Gastropoda, and Annelida.
