PROESTRUS Meaning and
Definition
-
Proestrus is a term used in veterinary medicine and animal reproduction to describe a phase in the reproductive cycle of female mammals. It is the initial phase of the estrous cycle, which is a recurring reproductive cycle experienced by most non-human mammals, including dogs, cats, and cows.
During proestrus, the female's body undergoes various physiological changes in preparation for mating and potential pregnancy. The primary characteristic of proestrus is the onset of sexual receptivity or heat. This is often accompanied by behavioral changes, such as increased vocalization, restlessness, and seeking attention from males.
Hormonal changes occur during proestrus as well. The levels of estrogen, a hormone responsible for the development and maturation of reproductive organs, gradually increase. This leads to the swelling and reddening of the vulva and increased vaginal secretions. Additionally, the female may attract males due to the release of pheromones.
The duration of proestrus can vary among species but typically lasts for several days to a week. It is followed by estrus, the period of maximum sexual receptivity, and eventually by metestrus, a less sexually active phase.
Proestrus is an essential part of the reproductive cycle as it signifies the beginning of the fertile period. It is a crucial time for animal breeders and veterinarians to assess the reproductive readiness of the female and plan for potential mating or artificial insemination.

Etymology of PROESTRUS
The word proestrus has its roots in the field of animal reproductive science, specifically pertaining to the estrous cycle in female mammals.
The term proestrus is derived from the combination of two Greek words: pro- meaning before or in front of, and oistros meaning frenzy or passion. In the context of the estrous cycle, proestrus refers to the initial stage or the period preceding estrus, which is the receptive phase during which the female is most likely to mate.
Therefore, the etymology of the word proestrus can be understood as before the frenzy or before the passionate phase.
