Substructure of the mammalian acrosome

Journal of Ultrastructure Research, 1972
Acrosome ultrastructure was analyzed in the Chinese hamster, mouse, rat, and rabbit. The plasma membrane overlying the acrosome of Chinese hamster and mouse spermatozoa is coated with minute vesicles and tubules in specific regions. These vesicles and tubules are localized in an area on the surface of the sperm head which seems to have a “sticky ...

[Acrosome reaction and fertilization].

Contraception, fertilite, sexualite (1992), 1994
The 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

The Acrosome Reaction

1956
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.
