Great ape menstrual cycles appear to be more regular and generally longer compared with humans. Orangutans cycles are approximately 29 days, gorillas 30 – 32 days, bonobos 32-35 days and chimpanzees ~37 days, though it can range from 31 – 36.7 days in this species.
In gibbons and chimpanzees, the menstrual bleeding can be detected easily whereas in orangutans and gorillas bleeding is quite less and therefore the menstruation is visible only on closer inspection. Gorillas, chimpanzees, monkeys, orangutans and humans are all primates and therefore they all show menstruation cycle.
Just like human females, chimp menstrual cycles vary from chimp to chimp. Some chimps have shorter cycles, around 28 days; others have cycles as long as 45 days (Elder 359).
Most of the menstruating species, including humans, are primates [2]. Besides in primates, menstruation has been observed only in the spiny mouse [3], 3–5 species of bats [4–6], and the elephant shrews [7] (Figure 1).
Being 13-18 weeks in length, the elephant estrous cycle is the longest amongst all studied non-seasonal mammals to date. Progesterone increases 1-3 days after ovulation, indicating the start of the luteal phase, which lasts 6-12 weeks.
Not only do animals enjoy the deed, they also likely have orgasms, Bekoff said. They are difficult to measure directly but by watching facial expressions, body movements and muscle relaxation, many scientists have concluded that animals reach a pleasurable climax, he said.

Their uterine system is similar to a horse or cow. Each female dolphin tends to use either the right or left ovary. There is some indication that they switch the ovary/uterus they are using later in life. Female dolphins are thought to be “spontaneous” ovulators and don't necessarily have a set cycle.
A shark's sense of smell is powerful – it allows them to find prey from hundreds of yards away. Menstrual blood in the water could be detected by a shark, just like any urine or other bodily fluids. However, there is no positive evidence that menstruation is a factor in shark bites.
The reproductive cycle, in female primates, called the menstrual cycle, comprises 28 days in a healthy female. Primata is the order to which monkeys, apes and human beings belong. The duration of the menstrual cycle varies in different females as it is dependent upon a number of factors.
Females reach sexual maturity at 7 – 8 years of age, but normally will not breed until several years later. Males reach sexual maturity about 11 – 13 years, but normally do not father offspring until they reach silverback status and have a family group of their own (about 15 – 20 yrs of age).
New European research has found that although women's menstrual cycles don't affect which men they are attracted to, as previously thought, women do appear to find all men slightly more attractive when in the fertile stage of their cycle.
“Most women bleed only 60 milliliters (about three to four tablespoons) over five whole days,” says Dr. Haughton. Even if you're free-flowing into the pool for five hours, there's no way that water is going to turn into the Red Sea with the amount of blood coming out of your body.
People believe that period blood nourishes their skin, clears acne, and benefits the skin in a lot of ways. But this is not true and has no scientific evidence,” Dr Geetika Mittal Gupta, a dermatologist, said on Instagram.
Being "in heat," technically known as estrus, is the part of a mammal's reproductive cycle when a female mammal is sexually receptive to the males of her species. This doesn't really happen in human beings.
As a woman, your period is your body's way of releasing tissue that it no longer needs. Every month, your body prepares for pregnancy. The lining of your uterus gets thicker as preparation for nurturing a fertilized egg. An egg is released and is ready to be fertilized and settle in the lining of your uterus.
The mare's normal cycling period is from approximately March through September. During this period, the mare undergoes a series of cycles, each approximately 22 days in length. The estrous cycle is divided into two physiological parts: estrus and diestrus.
These results provide evidence that captive aging female baboons experience menstrual cycle changes similar to peri- and menopausal women.
A long postreproductive lifespan may distinguish women from all other female primates. A long-held consensus among reproductive scientists has been that our closest living relative, the chimpanzee (Pan troglodytes), experiences menstrual cycles until death.
Mating is done while both gorillas are on the ground with the female (which is normally smaller than the dominant silverback) appearing to kneel on the ground while the male is on top throughout the copulation.
Up until now, scientists have been aware that dolphins possess clitorises (much like all female mammals), but they weren't sure whether they experienced pleasure. Research now confirms that the animals do experience pleasure when having sex, due to their “large” clitorises.
Unlike many other animals, dolphins do not mate purely for procreation. Rather, these highly social and intelligent animals have sex for pleasure as well. Further, this means they can have sex throughout the year, rather than being limited to a mating season.
Some girls are successful even if they get no help at all. But any help at all can go a long way toward your daughter feeling comfortable with her body, and bravo for trying. Don't forget to tell them how to take the damn thing out!
Use a tampon, sponge, or cup while swimming
If you can't or don't want to use a tampon or alternative product like a sponge or menstrual cup, you have a few options. If your flow is light, you can wear absorbent swimwear or a dark-colored suit to prevent stains.
Most of the time, blood won't leak out. If you do wear a tampon in the bath or shower, it's a good idea to change your tampon when you get out. The tampon can get wet from the bath or shower. It may not be able to absorb as much blood from your period as a fresh one can.
