does menstrual cycle also take place in animals,if yes,when,why it occur?how do we come to know it?

Answer 1

Yes it does. Its called "going into heat" if you have a cat or dog you'll know this by the yowling and attempts to escape. It happens about once every two months for my cat and lasts about a week and a half. It also lasts for most animals all through spring.

We know that animals go into heat because of times when they have an increased desire to mate. Plus all mammals ovulate, thus they have a menstraul cycle. Its not as bad or as noticable as a human's though, except in there behavoir.

Male animals also have a period of increased desire to mate. It's usually called a "rutt"

Answer 2

The estrous cycle (also oestrous cycle; originally derived from Latin oestrus) refers to the recurring physiologic changes that are induced by reproductive hormones in most mammalian placental females; humans and some primates, bats, and shrews are the only mammals who undergo a menstrual cycle instead. Estrus cycles start after puberty in sexually mature females and are interrupted by anestrous phases. Typically estrus cycles continue until death. Some animals may display bloody vaginal discharge, often mistaken for menstruation.

Differences from the menstrual cycle

Mammals share the same reproductive system, including the regulatory hypothalamic system that releases gonadotropin releasing hormone in pulses, the pituitary that secretes follicle stimulating hormone and luteinizing hormone, and the sex hormones including estrogens and progesterone. However, species vary significantly in the detailed functioning. One difference is that animals that have estrous cycles reabsorb the endometrium if conception does not occur during that cycle. Animals that have menstrual cycles shed the endometrium through menstruation instead. Another difference is sexual activity. In species with estrous cycles, females are generally only sexually active during the estrous phase of their cycle. This is also referred to as being "in heat." In contrast, females of species with menstrual cycles can be sexually active at any time in their cycle, even when they are not about to ovulate. Humans, unlike some other species, do not have any external signs to signal receptivity at ovulation. Research has shown however, that women tend to have more sexual thoughts and are most prone to sexual activity right before ovulation.
