The peanut-agglutinin assay is used to assess the acrosomal status of sperm. This assay is an indicator of semen quality as male infertility may be caused by spermatozoa lacking intact acrosomes at ejaculation. Acrosomal status after induction of the acrosome reaction can be assessed by microscopy or flow cytometry with fluorescently labeled lectins ...

Capacitation and the acrosome reaction in equine sperm
Animal Reproduction Science, 2001During sexual reproduction, the sperm and oocyte must fuse before the production of a diploid zygote can proceed. In mammals such as equids, fusion depends critically on complex changes in the plasma membrane of the sperm and, not surprisingly, this membrane differs markedly from that of somatic cells.

A Model for the Acrosome Reaction in Mammalian Sperm
Bulletin of Mathematical Biology, 2018The acrosome reaction is a complex, calcium-dependent reaction that results in an exocytotic event required for successful fertilization of the egg. It has long been thought that the acrosome reaction occurs upon sperm binding to the zona pellucida, a viscoelastic layer surrounding the oocyte.

Cellular biology of capacitation and the acrosome reaction
Human Reproduction, 1995For successful fertilization in mammals, spermatozoa must complete capacitation and then undergo the acrosome reaction, an exocytotic process that allows cells to bind to and then penetrate the zona pellucida. After penetration has been achieved, acrosome-reacted cells are capable of fusing with the oocyte plasma membrane, thereby activating the oocyte

Receptors and channels regulating acrosome reactions
Human Fertility, 1999Prospective clinical studies informed by cloning and sequencing of sperm surface receptors and metal ion channels have elucidated critical early steps in the acrosome reaction that explain aspects of metal ion-related male infertility. Induction of the acrosome reaction is proposed to include non-nuclear progesterone receptor activation of Shaker ...

Site of Mammalian Sperm Acrosome Reaction
2016Until recently, no special attention has been paid to the question of the site of mammalian sperm acrosome reaction (AR) in the female reproductive tract. Because AR is an essential process that enables the spermatozoon to fertilize, it is generally believed that it occurs at a specific step during sperm-egg interaction.

Acrosome reaction and fertility.
International journal of andrology, 1996The acrosome reaction is important for fertilization. To diagnose this reaction the simple gelatin lysis test, the triple-stain technique or labelling with lectins can be used. The role of pentoxifylline in enhancing the acrosome reaction remains to be determined.
