ESTROUS CYCLE Meaning and
Definition
-
The estrous cycle refers to the recurring reproductive cycle that occurs in most mammalian female species, including humans. It is characterized by hormonal and physiological changes that prepare the female body for mating and potential pregnancy. The estrous cycle consists of several distinct phases and is regulated by various hormones.
The cycle begins with the proestrus phase, during which the levels of estrogen hormone gradually rise, stimulating the growth and maturation of the uterine lining. This phase is typically marked by a decrease in appetite and restlessness in females. It is followed by the estrus phase, also known as "heat," during which the female is sexually receptive and may actively seek a mate. The levels of estrogen peak during this phase, leading to changes in behavior, such as increased vocalization and physical displays.
If mating occurs, pregnancy may follow, and the female enters the metestrus and diestrus phases. These phases involve the secretion of progesterone hormone, which maintains the uterine lining and prepares it for potential implantation of a fertilized egg. If pregnancy does not occur, the cycle ends with the transition to the anestrus phase, a period of reproductive quiescence characterized by low hormone levels and absence of estrus behavior.
The duration and regularity of the estrous cycle vary among species, with some having short cycles of a few days, while others have longer cycles lasting weeks or months. Understanding the estrous cycle is crucial in animal breeding and reproductive research, as it influences fertility, timing of mating, and overall reproductive health in female mammals.

Etymology of ESTROUS CYCLE
The word "estrous" is derived from the Latin word "oestrus", which means "frenzy" or "passion". It is related to the Greek word "οἶστρος" (oistros), which has a similar meaning. In the context of animals, "estrus" refers to a particular phase in the reproductive cycle of mammals, during which they are sexually receptive and potentially fertile. The term "estrus cycle" is used to describe the recurring pattern of hormonal and physiological changes that occur in female mammals during this reproductive cycle.
