The union of male and female gametes to form a zygote. The cellular process that joins two lipid bilayers to form a single membrane. The binding and fusion of a sperm, having penetrated the zona pellucida, with the plasma membrane of the oocyte. Binding occurs at the posterior (post-acrosomal) region of the sperm head. Any process that stops or prevents the binding and fusion of a sperm to the oocyte plasma membrane. Any process that modulates the binding and fusion of a sperm to the oocyte plasma membrane. The joining of two or more lipid bilayer membranes that surround a cell.
