ekstrous

Extrous refers to a phase in the reproductive cycle of many female mammals. It is the period of sexual receptivity, also known as estrus or heat. During ekstrous, a female is physiologically and behaviorally receptive to mating. This phase is typically characterized by hormonal changes, most notably a surge in estrogen levels, which triggers the development of mature ovarian follicles and leads to ovulation. Behavioral signs of ekstrous can vary significantly among species but often include increased restlessness, vocalization, seeking out males, and specific postures that indicate readiness for mating.

The duration of ekstrous is also highly variable, ranging from a few hours to several days, depending on the species. Following ekstrous, the female enters the post-estrous phase, during which she is no longer receptive to mating. If fertilization does not occur, many mammals will enter another ekstrous cycle. The timing of ekstrous can be influenced by factors such as photoperiod (day length), temperature, and social cues from other individuals. Understanding ekstrous is crucial in animal breeding, wildlife management, and veterinary medicine as it directly impacts reproductive success and population dynamics.
