Acrosome Reaction | PDF | Cell Biology | Fertility Therefore, sperm cells go through a process known as the acrosome reaction, which is the reaction that occurs in the acrosome of the sperm as it approaches the egg. This shedding of the acrosome, or acrosome reaction, can be stimulated in vitro by substances a sperm cell may encounter naturally such as progesterone or follicular fluid, as well as the more commonly used calcium ionophore a23187.

Acrosome Reaction - Alchetron, The Free Social Encyclopedia

Acrosome Reaction - Alchetron, The Free Social Encyclopedia The sperm must undergo capacitation in the female's reproductive tract over several hours, which increases its motility and destabilizes its membrane, preparing it for the acrosome reaction, the enzymatic penetration of the egg's tough membrane, the zona pellucida, which surrounds the oocyte. Alchetron is a free social encyclopedia where you can search & share millions of topics which can be anything like movies, biographies, cities, news, free courses for students, cooking recipes etc. The acrosome reaction (ar) is defined as a process in which capacitated sperm bind to the zona pellucida of the egg, leading to the fusion of the outer acrosomal membrane with the plasma membrane, resulting in the release of acrosomal enzymes that facilitate fertilization and prevent polyspermy. This review describes the mechanism of fertilization vis a vis sperm membrane change, with a brief historical overview of the half century study of acrosome reaction.

In 2001, jimmy wales and larry sanger launched , a collaboratively edited, multilingual, open source, free internet encyclopedia supported by the non profit wikimedia foundation. The acrosome reaction is a crucial process in the fertilization of mammalian oocytes. it is a physiological reaction that occurs in the spermatozoon (sperm cell) as it approaches and penetrates the zona pellucida of the oocyte. The importance of acrosin in the acrosome reaction has been contested. it has been found through genetic knockout experiments that mouse spermatozoa lacking β acrosin (the active protease) still have the ability to penetrate the zona pellucida.
