It is generally considered a two-step process: first, male and female gamete clouds are stirred by the fluid flow, and second, sperm contact and penetrate an egg the exact contributions of larger-scale (stirring of gamete plumes) and smaller-scale (sperm-egg encounters) processes to fertilization success have not been established for even a.
