Description: Diagrams the phases of fertilization as: release of the sperm, approach, penetration, fusion, and activation, and examines the "how" of these phases. Shows Rothchild's diagrams of sperm actions explaining chemotaxis. Shows the process of fertilization using sea urchin eggs. Pictures through microcinematography a sperm penetrating an egg, the enlargement of the sperm head, the production of the asters from the middle piece, and formation of the new cell spindles.

Concludes that since several of these operations cause parthenogenesis, the precise method of activation is still unknown.
