If the stress persisted, there could be an exhaustion or failure of the regulatory system involved. The entire set of events, culminating in a breakdown of physiological regulation, was named the . by Seyle.

This superimposition of the external environment on the endogenous feedback loops may result in an alteration of the timing of initiation and the rate of change in the maturation process which results in adult sexual and reproductive function.

This paper examines the range and relative importance of the environmental factors which are known from observational studies to influence reproductive performance in ewes of different genotypes.
