A biological process that directly contributes to the process of producing new individuals by one or two organisms. The new individuals inherit some proportion of their genetic material from the parent or parents. Any process that modulates the frequency, rate or extent of the acrosome reaction. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. A process, occurring at the cellular level, that is involved in the reproductive function of a multicellular or single-celled organism. A process of secretion by a cell that results in the release of intracellular molecules (e.g. hormones, matrix proteins) contained within a membrane-bounded vesicle by fusion of the vesicle with the plasma membrane of a cell. This is the process whereby most molecules are secreted from eukaryotic cells. The union of male and female gametes to form a zygote. The union of gametes of opposite sexes during the process of sexual reproduction to form a zygote. It involves the fusion of the gametic nuclei (karyogamy) and cytoplasm (plasmogamy). The fusion of the plasma membrane of the sperm with the outer acrosomal membrane. The proteolytic digestion of components in the acrosomal matrix that allows for their release into the egg. The dispersal of the components allows for the inner acrosomal membrane to interact with the egg. The release of intracellular molecules contained within the acrosomal granule by fusion of the vesicle with the plasma membrane of the oocyte, requiring calcium ions. The posttranslational phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine that is part of the acrosome reaction. The release of intracellular molecules (e.g. hormones, matrix proteins) contained within a membrane-bounded vesicle by fusion of the vesicle with the plasma membrane of a cell, requiring the presence of calcium ions. The actin-based process by which a protein is transported to, or maintained in, a specific location in the sperm as part of the acrosome reaction. Any process that activates or increases the frequency, rate or extent of actin polymerization as part of the acrosome reaction. The discharge, by sperm, of a single, anterior secretory granule following the sperm's attachment to the zona pellucida surrounding the oocyte. The process begins with the fusion of the outer acrosomal membrane with the sperm plasma membrane and ends with the exocytosis of the acrosomal contents into the egg.
