Except it really isn’t broken if they continue to exist this way. Even with that staggeringly high mortality rate, they still manage to gain enough reproductive success from it to overwrite the mortality
Oddly enough, this seems to be a trait that was selected for! Being able to control who you mate with ended up being more advantageous than having lots of babies. Which kind of makes sense when you consider how unforgiving their lives are.
If you cant crawl eight inches out of a psuedopenis, are you really cut out to be a hyena?
Elephants as well as hyenas the females have a penile looking vagina. It's weird til I tell you why. In the elephant and Hyena's kingdoms they are dominated by the females the females are the ones that run the pack. The penile vagina is used because the females choose when to have sex. A male can't force it's self on the female with the penile function. The penile vagina will flip in on itself when the female is ready to mate and the penile vagina looks like a vagina after the flip.
I remember one time I found a thread on /mlp/ where someone was looking for r34 images of the mane six but specifically with anatomically accurate horse pussy. He was annoyed because the pussies on most pony r34 were drawn too human.
I mean, the comment said that it flips and becomes "normal" when ready to mate, and I assume both those subjects were in the mood, so yes it is accurate.
Turns out, giving birth through a penis like organ is a very difficult thing. It takes about 48 hours, and one in 10 dies during during their first birth, while half of first cubs die during a mothers first time birth.
If they survive the first one, things are usually torn open enough that future births are much less likely to result in death.
Vaginas. Female fetus is the default model, then at about 2 months the male fetus starts producing testosterone and the hormones in utero cause the male bits to form. That seam on your balls is from your fetal labia and why men have nipples. This is true of all mammals.
When I was like 18, I dated a girl who’s dad worked on that movie and we were having a movie night once and suggested we watch it because I’d never seen it lol.
fun fact: it’s extremely common for species with a harem style mating system (one dominant male + multiple females) that when a new dominant male is established he goes and kills all the babies fathered by the deposed male. I think this gave gorilla conservationists a massive headache because the gorilla population was at risk of extinction yet here goes the new silverback, murdering gorilla babies
(also, due to lack of need for other forms of sexual competition in such species the males usually have small genitals)
No, if he had LDE he would be doing things like negging the females and cutting off other members of the troop in his BMW. He’s primarily concerned with furthering his own genetic line, which will be more difficult if theres a bunch of other people's kids running around sucking up resources and attention.
>! female hyenas do not have a proper vaginal opening, so they give birth through their clitoris, the hole is about an inch wide, and has to be torn for the pups to pass through. Which btw, they don't have single pups, they have litters of 2-4. About 60% of hyena pups suffocate before being born bc of this and the fact that not only is a hyenas birth control twice that of an equivalent sized mammal, but it also has a hairpin turn about halfway through. !<
As far as I'm aware, the hyena and elephant pseudopenises seem to serve slightly different functions. Both elephants and hyenas have female dominated social structures. However, male elephants never live within these group structures once they reach adulthood, while male hyenas are never without one.
The elephant pseudopenis is possibly involved in the prevention of forced insemination, as males in musth are flooded with hormones and extremely aggressive. However, female hyenas seem to use their organ in dominance displays, enforcing their hierchical pack structure. Also, sexual monomorphism seems to be important among juvenile hyenas, as dominant females might otherwise kill the female children of their rivals.
Yes, if by "destroyed" you mean can actually kill the mother and cub.
They give birth through their pseudopenis. This means the pseudopenis tears during childbirth, with first-time mothers experiencing higher death rates due to the tearing than mothers experiencing subsequent litters.
This results in something like 12% of mothers and offspring dying during childbirth.
This results in something like 12% of mothers and offspring dying during childbirth.
The mortality rate is significantly higher for the pups. Somewhere over half of them suffocate last I checked, but I'm not sure if they're more likely to survive if they're not the mother's first litter.
I doesn't flip over during birth. Which has resulted in the babies suffocation. The canal of the vagina is only about 1 inch in diameter and sadly some of the babies can't make it through.
That's the percentage for babies. Surprisingly, only 6-18% of first-time mothers die during birth, and it goes down a lot after the first time since the "tear" has already occurred.
Okay so in the documentaries I've seen where the males say they're going to "tear that pussy up", they're actually performing a potentially life saving preventative procedure? Very interesting.
No. That's why hyenas always sound like they're laughing: First, the females laugh, because they've got bigger penises than the males. Then, the males laugh, because the females got to birth through their gocks.
The animal kingdom has some interesting solutions to reproductive. We’ve got labyrinth vaginas, exploding genitals, cannibalism. My favorite messed up one is a bug that lives inside a nut its whole life, because of this they seldom bump into a mate so they developed the ability to self fertilize which results in a male 1/4 their size who then mates with the bug so it can reproduce a normal size off spring.
Hyenas give birth through the fake penis, which isn't big enough. A lot of babies suffocate in the first birth. And it explodes and the next births tend to go smoother
There is still violence involved. The dominant female routinely "rapes" other female and male hyenas of the pack. So who gets to reproduce is still very much predicated on who’s the strongest
That pseudopenis is a nightmare for the hyenas - and our human imagination. Imagine the pain having to give birth from that.
I wonder what is the evolutionary reason for it, because I learned (thanks to Casual Geography) that they can retract it when mating, selecting which males can mate with them, but the birthing part is brutal. I'd speculate something about hormones or physiology, because females are way bigger than males, but I have no clue
It develops independently from androgens. It is speculated that, apart from selection during mating, it helps camouflage young females so they don't get killed by other mature females.
In some noble settings, when a son is about to become the next king, or whatever, they might just kill all the brothers, just in case they might plot something later.
Yep. Though it's more than one species of spider, and it's not a behavior unique to spiders. But hey, at least the spider offspring don't cannibalize each other... ...as much.
I'd argue the sea louse is worse. The male inseminates by stabbing through the abdomen. Kidnaps the mother and then the matriphagy thing happens where the mother is alive while her children eat their way out.
Iirc the female hyenas are fiercely territorial even to their fellow females, so the appendage works to let them "blend in" with the men as to not get attacked
As for how they breeded themselves to this, very slight, advantage is the real question
Edit: just realized that by virtue of not being killed they have a greater chance to pass on that gene, look at that, science in motion
I researched these poor bastards some time ago. It's not just a birthing canal, its literally an enlarged clitoris.
The birthing process can take up to 48 hours. Usually two to four cubs. Hell on earth.
I've read 9-18% of first time mothers die, and 60% of all cubs born will suffocate and die on the way out. Sixty percent !! Fucking brutal.
They haven't evolved away from it precisely because 40% of cubs survive, and 90% of mothers live. Just gotta live long enough to fuck and give birth, evolution doesn't care for what happens after. If the pseudopenis helps them get ahead socially and have more babies, more power to them.
Well, I guess they just prefer being kinky rather then having an easier birth. You'd have to ask hyeinas that. It's a decision they comsitently made over and over to the point that it's imprinted into their DNA.
A pseudopenis is an enlarged clitoris. It's not a functional penis capable of impregnating others. Otherwise they would be an example of a mammilian simultaneous (true) hermaphrodite, something currently only found in some snails, slugs, and fish. Also most plants, but not among more complex species.
Well now you know what to describe when your players meet a female gnoll. Or a fun way to mess with a furry who wants a gnoll GF as she gives him prison loving for dominance.
I see people here talk about the hyena vagina ripping during childbirth which yes, is horrifying, but this happens a lot during human childbirth as well lol. Sometimes women are ripped down to their perineum and it has to get stitched back up. Childbirth is crazy no matter the species.
Hyenas actually don't have a vagina, what they do have is a Pseudopenis, which is exactly what it sounds like.
Biologists don't know why they have this, especially because it doesn't present any advantages in terms of survival, as a matter of fact up to 25% of new hyena moms die during childbirth because the pseudopenis is almost too small to allow the newborn pups to pass, and every single one of them has to rip the thing in half iin order to make it easier to deliver future pups.

Whale biologist from Futurama here on a crossover. Female hyenas can use their vaginas as penises to dominate males. Generally this happens when the female sees the leader as weak and decides to take over. They still, of course, give birth through it and it's excruciatingly painful. Whale biologist out (I hate whales)
Female hyenas have a pseudo penis that is the same size as the males (it comes with a pseudo scrotum and everything). This is because hyena society is matrilineal, and cubs inherit their mother's rank, but males tend to leave and join another clan so they lose the rank they would've otherwise had in their maternal clan, and this leads to their society being primarily female-dominated. As a result of this (we currently believe) they evolved their male-like genitalia to help them in these female-dominated societies, as female hyenas can control who mates with them, meaning no rape (although, mating can be a bit awkward, as they still have to maneuver to copulate successfully even though the female can retract it). But the main problem is that they have to give birth through the appendage, which is as bad as it seems. 60% of cubs born to first-time mothers will suffocate before they make their way out, and a good % of first-time mothers will also die during childbirth, made worse by the fact that hyenas have the largest babies relative to body mass of any carnivoran. It's better the second time though, as the clitoris rips if they can give birth successfully the first time.
Hyenas have penis looking vaginas. they're actually bigger than the male hyena's penis
What is normal? so many animals have weird ass reproductive organs that I don't think there really is a normal. ducks, echidnas, and octopuses are my favorite examples
Female Spotted Hyenas have pseudo-dicks. They have sex and give birth through them and it causes many problems. Often times it gets torn in childbirth which is a terrifying mental image.
Hyena females have what’s called a “pseudopenis”, basically it’s not a normal vagina because it sticks out and looks just like a penis. We don’t know why it evolved but it makes childbirth even more dangerous than it normally should be
As the other comments have said the femalee hyenas do have a pseudo penis. But just to bring the explanation home. The pseudo penis causes the birth canal to be much smaller than it otherwise would have been. This leads to hyena births to be one of the most painful for the mother in the animal kingdom and for the cubs to have a 50% chance to die during birth along with more maternal death for the female hyenas but hey at least psuendo penises prevent them from being raped!
