## Abstract Egg‐jelly is composed of a network of fibrous components and contains substances regulating the sperm‐egg interaction. Many studies on the latter have been conducted, whereas the role of the egg‐jelly structure in fertilization has not yet been fully assessed. In this study, we examined

The significance of egg-jelly layers in internal fertilization was evaluated in the newt, Cynops pyrrhogaster. In this species, six egg-jelly layers, J1, J2, J3, J4, J5 and the outermost J6 layers, are accumulated on the surface of the fertilizable eggs in pars convoluta of the oviduct. When a large

## Abstract The acrosome reaction of newt sperm is induced at the surface of egg jelly and the acrosome‐reacted sperm acquire the ability to bind to the vitelline envelope. However, because the substance that induces the acrosome reaction has not been identified, the mechanism by which the acrosome
