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. The process whereby the egg becomes metabolically active, initiates protein and DNA synthesis and undergoes structural changes to its cortex and/or cytoplasm. 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. 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 negative regulation of fertilization process that takes place as part of egg activation, ensuring that only a single sperm fertilizes the egg. Any process that decreases the rate, frequency or extent of fertilization. Fertilization is 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). 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. Any process that activates or increases the frequency, rate or extent of cortical granule exocytosis by directing movement of calcium ions (Ca2+) into the cytosol. The process of secretion by a cell that results in the release of intracellular molecules contained within a cortical granule by fusion of the vesicle with the plasma membrane of a cell. A cortical granule is a specialized secretory vesicle that is released during egg activation that changes the surface of the egg to prevent polyspermy.
