The union of male and female gametes to form a zygote. The fusion of the plasma membrane of the sperm with the outer acrosomal membrane. The cellular process that joins two lipid bilayers to form a single membrane. 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. A process, occurring at the cellular level, that is involved in the reproductive function of a multicellular or single-celled organism. The membrane organization process that joins two lipid bilayers to form a single membrane. 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. A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a membrane. A membrane is a double layer of lipid molecules that encloses all cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins.
