METESTRUS Meaning and
Definition
-
Metestrus is a phase in the estrous cycle of female mammals, referring specifically to the transitional period between estrus and diestrus. It is characterized by the regression of certain reproductive structures and the preparation for a new estrous cycle. During this stage, the corpus luteum, which forms in the ovary after ovulation, undergoes involution or shrinking in size. This marks the decline in progesterone production, leading to changes in the female reproductive tract.
In metestrus, the lining of the uterus, also known as the endometrium, starts to regress and the blood supply decreases. Additionally, the cornified cells in the vagina start to slough off, indicating the end of estrus. These physiological changes prepare the female mammal for another round of follicular development and subsequent estrus.
The duration of metestrus varies among different species, but it generally lasts for a relatively short period compared to diestrus or proestrus. Throughout metestrus, the female is not receptive to mating, as she is not in a state of sexual receptivity. However, it is important to note that the specific duration and characteristics of metestrus can vary between individual animals and species. Studying metestrus is crucial in understanding the reproductive physiology and behaviors of female mammals, as well as for evaluating the timing and success of breeding.

Etymology of METESTRUS
The word "metestrus" is derived from the combination of two Greek roots: "meta" and "oistros".
The prefix "meta" in Greek means "after" or "beyond", often indicating a change or transformation.
The second part, "oistros", refers to a word meaning "gadfly" or "stinging insect". It is often associated with intense agitation or desire.
When combined, "meta" and "oistros" form "metestrus", a term used in biology, specifically in the study of reproductive cycles in female mammals. Metestrus is a phase in the estrous cycle, which occurs after the period of estrus (when female animals are sexually receptive) and before the subsequent stage known as diestrus.
