The estrous cycle occurs in most mammals, including dogs and cats, and is typically shorter and more predictable than the menstrual cycle in humans. In the estrous cycle, females are only sexually receptive during a specific period, while in the menstrual cycle in humans, women are sexually receptive throughout the cycle but can only conceive during ovulation.

Do butterflies have periods?
No, butterflies do not have menstrual cycles so that means they don't have periods. Only primates (this includes humans), jumping shrews, and quite a few species of bats have menstrual cycles. There is another type of cycle called an estrous cycle that most other female mammals have, but butterflies are not mammals.
Do men have menstrual cycles?
No, men do not have menstrual cycles. Menstrual cycles are unique to people with female reproductive systems and involve the shedding of the uterine lining if pregnancy does not occur. Men do not have the necessary anatomy for this process.
When do a woman stop menstrual cycle?
Menstrual cycles will come to an end as women go through menopause. Women's menstrual cycles will also be stopped if they fall pregnant, while on hormonal birth control, or after a hysterectomy.
Can it be happend that the menstrual cycle last for 2 days?
Yes, it is possible for a menstrual cycle to last for only 2 days. Menstrual cycles can vary in length and intensity from person to person, and some individuals may have shorter or irregular cycles. If you are concerned about the length of your menstrual cycle, it is recommended to speak with a healthcare provider for further evaluation.
Does the menstrual cycle last an average of 3 7 days?
The menstrual cycle typically lasts between 21 to 35 days, with the average being around 28 days. The actual menstrual bleeding usually lasts between 3 to 7 days for most women.
Does a doe as in deer have a menstrual cycle?
No. Humans are the only mammals with menstrual cycles. Deer, as well as other mammals, have estrous cycles. http://en.wikipedia.org/wiki/Estrous_cycle
What is the average estrous length for women?
The typical menstrual cycle length is around 28 days, but everyone is different. It's also perfectly normal for there to be a few days variation from one cycle to the next cycle.
What is the length of the estrous cycle in pigs How does this compare with humans?
The estrous cycle of pigs is 21 days. Humans have a menstrual cycle which can last from 21-35 days.
What fish have menstrual cycles?
only people have a menstrual cycle but mammals have something called Estrous cycle and there is sometimes bloody discharge. fish are not mammals and they don't have it.
Do hamsters get periods?
No, hamsters do not have menstrual periods like humans do. Hamsters have estrous cycles where they go into heat, during which they are receptive to mating.
What is the difference between estrous and menstrual cycle?
The estrous cycle comprises the recurring physiologic changes that are induced by reproductive hormones in most mammalian placental females. Humans and great apes undergo a menstrual cycle instead. Estrous cycles start after puberty in sexually mature females and are interrupted by anestrous phases. Typically estrous cycles continue until death. Some animals may display bloody vaginal discharge, often mistaken for menstruation. 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 (see below for an explanation of the different phases in an estrous 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 obvious external signs to signal receptivity at ovulation (concealed ovulation). Research has shown however, that women tend to have more sexual thoughts and are most prone to sexual activity right before ovulation. Hope this helps! Best of Luck!
What animals have periods?
Humans and chimpanzees are the only animals that have "periods" or menstrual cycles. Other animals of the animal kingdom undergo Estrus, or heat periods (spikes in Estrogen output) during their Estrous cycle.
Do sheep have menstrual cycles?
No
Do other animals have periods?
Yes, some species of mammals, such as monkeys, apes, and some bats, have menstrual cycles similar to humans. Other animals, like dogs and cats, have estrous cycles, which are similar but do not involve a shedding of the uterine lining like human periods.
Do butterflies have periods?
No, butterflies do not have menstrual cycles so that means they don't have periods. Only primates (this includes humans), jumping shrews, and quite a few species of bats have menstrual cycles. There is another type of cycle called an estrous cycle that most other female mammals have, but butterflies are not mammals.

Can Cipro affect your menstrual period?
