es·trous cycle

(ĕs′trəs)
The series of bodily changes that occur in the female of most mammals from one period of estrus to another. The estrous cycle usually takes place during a specific period known as the breeding season, which ensures that the young are born at a time when the chance of survival is greatest. The length of the cycle varies from species to species.
