The estrous cycle or oestrus cycle (derived from Latin oestrus "frenzy", originally from Greek οἶστρος oîstros "gadfly") is the recurring physiological changes that are induced by reproductive hormones in most mammalian therian females. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phases or by pregnancies. Typically, estrous cycles continue until death. Some animals may display bloody vaginal discharge, often mistaken for menstruation.
