Capacitation and acrosome reactions of mammalian spermatozoa and their value as a functional test for fertilizing ability

, : Capacitation and acrosome reactions of mammalian spermatozoa and their value as a functional test for fertilizing ability. Biologisches Zentralblatt 108(1): 41-62

In a review of work on farm livestock, laboratory mammals, other mammals and man, consideration is given ot the physiological changes in the spermatozoon occurring before and during fertilization. The changes taking place in the spermatozoon, particularly in the structure of the sperm membrane, before and after contact with the zona pellucida of the oocyte, are discussed.
