In our life cycle, women have to go through the menstrual cycle at certain times of their lives to reproduce. Now it is said that the need for reproduction is not limited only to humans. All animals in the biosphere want to perpetuate their offspring, so do other animals also have to go through such cycles?
First, the menstrual cycle is the shedding of the lining of the uterus (endometrium). It occurs regularly in sexually reproductive age females (any female mammals) of certain mammalian species. Although many disagree on this definition, this process was generally thought to be limited to primates (a class of mammals with advanced arms, legs, and large brains that includes humans, monkeys, hanumans, gorillas, and lemurs). But at present, apart from primates, elephants, red kangaroos, lions, cats, dogs, special species of bats, rats have evidence of such physiological processes.
In general, we understand the menstrual cycle as bleeding in a special process, but this cycle is manifested in different ways in the body of different species. For example: cat. Cats are polyestrous breeders, which means they experience a hormonal kick during their menstrual cycle, which happens 3-5 times a year. During this time, the changes in their body look very similar to humans. But bleeding is not visible externally. In particular, there may be light bleeding which is very little! Sometimes this little bleeding is not even noticeable.
Elephants, on the other hand, have a very similar process to humans, a menstruating elephant uses grass as its sanitary towel and usually stays in one place during that period (Source: Murchison Falls National Park hosts).
On the other hand, a female tigress can enter estrus (the time when a female is receptive and able to conceive young) every three to nine weeks and her receptiveness lasts three to six days.
And in the case of bats, the bat stays in its habitat for 33 days and rests with this change in its body. In their case, bleeding occurs only for 1 day, other days there are only physiological changes. A preovulatory follicle is found in the ovary on day 18 when LH and FSH levels reach their maxima, with a thick endometrium.
In this way, some physiological changes occur in all animals capable of conception in the organism. But that doesn’t mean it’s exactly the same process as humans or other primates.
