Nature is full of fascinating and sometimes brutal adaptations, but few are as shocking as the birthing process of the spotted hyena. You might think childbirth is a universally painful experience, but hyenas take it to an entirely new level.
Female hyenas have one of the most unusual reproductive anatomies in the animal kingdom—what appears to be a penis is actually an elongated clitoris, known as a pseudo-penis. This rare adaptation makes mating, birth, and survival incredibly difficult for both mother and cubs.
Let’s dive into the science, struggles, and evolutionary mysteries behind why hyenas experience one of the most challenging births in the wild.
Hyenas’ Unique Reproductive Anatomy: A Bizarre Evolutionary Twist

The female spotted hyena (Crocuta crocuta) is unlike any other mammal when it comes to reproduction. Unlike most female mammals, hyenas have no external vaginal opening. Instead, their labia are fused together, forming a pseudo-scrotum, and their clitoris is elongated into what resembles a fully functional penis.
This means that both mating and giving birth happen through a narrow, tough, and inflexible canal—a structure that poses serious risks to both mother and cubs.
But why would evolution favor such an extreme adaptation? The answer lies in hyena social structure and dominance.
The Link Between Dominance and Reproductive Anatomy
Hyenas live in strict matriarchal societies, where females outrank males in dominance. The unusual reproductive anatomy is believed to be an evolutionary adaptation linked to social hierarchy.
- A Display of Strength: A larger pseudo-penis might act as a dominance signal, making it clear which females hold power in the clan.
- Hormonal Influence: Female hyenas have higher testosterone levels than males, leading to increased aggression and dominance over the pack.
- Mating Challenges: Males must earn the right to mate, as females control copulation with their complicated anatomy.

While this system gives females power, it comes at a terrible cost when it’s time to give birth.
Why Giving Birth Is So Dangerous for Hyenas
Imagine trying to push a newborn through a passage too small, too rigid, and highly prone to tearing. That’s exactly what female hyenas go through every time they give birth.
Here’s what makes hyena birth so deadly:
- A Super Tight Birth Canal
- The pseudo-penis acts as the only birth canal, but it is long, narrow, and lacks the elasticity of a normal vagina.
- This makes labor extremely difficult and painful, with a high chance of the tissue tearing.
- First-Time Mothers Face the Worst Risks
- Many first-time mothers do not survive the birthing process due to severe ruptures.
- Those who do survive often suffer from long-term damage to their reproductive organs.
- High Cub Mortality Rate
- A staggering 60% of hyena cubs suffocate before they are fully delivered.
- Since the birth canal is so tight, cubs often become trapped and die before they can emerge.
- A Painful Recovery Process
- After birth, the pseudo-penis often ruptures completely, forcing it to heal over time.
- Mothers suffer weeks of pain and vulnerability while their bodies recover.
Despite these brutal challenges, hyenas continue to thrive, and their unique reproductive system has remained largely unchanged for millions of years.
How Do Hyenas Mate? The Struggles of Reproduction

If you think birth is difficult for hyenas, mating is no easier. Males must overcome significant anatomical and social obstacles just to reproduce.
- Males Are Submissive to Females
- Unlike in many species where males dominate, male hyenas are the weaker sex in both power and ranking.
- They must approach females cautiously, often displaying submissive behavior to gain approval.
- Navigating the Pseudo-Penis
- Since females have no traditional vaginal opening, males must carefully maneuver through the pseudo-penis to copulate successfully.
- This requires both patience and precise positioning, making it one of the most complex mating processes in the animal world.
- Only the Strongest Males Get to Reproduce
- Males don’t fight each other for dominance like in other species. Instead, they must earn the female’s trust over time.
- Females choose mates based on persistence, patience, and respect, ensuring only the most determined males pass on their genes.

Given how dangerous and inefficient the reproductive process is for hyenas, one might wonder why evolution hasn’t corrected this issue.
The answer lies in survival strategy and social dynamics.
- Matriarchal Control Guarantees Stronger Cubs
- By limiting mating to only the most persistent males, female hyenas ensure that their cubs inherit strong genetics.
- This method prevents weaker genes from spreading, keeping the species robust.
- Higher Testosterone Helps With Survival
- The same high testosterone that makes birth difficult also makes female hyenas stronger and more aggressive.
- This aggression helps protect their cubs and maintain dominance in their environment.
- Fewer Cubs = More Resources
- Since many cubs don’t survive birth, the ones that do are often given more attention and resources.
- This ensures the strongest cubs make it to adulthood, increasing the clan’s overall survival rate.
The Resilience of the Spotted Hyena
Despite their brutal birthing process, hyenas have thrived for millions of years. Their ability to adapt, dominate, and survive proves just how powerful evolutionary trade-offs can be.
- They are among Africa’s most successful predators, competing with lions for food.
- Their clans are ruled by powerful females, ensuring only the strongest members survive.
- They have some of the most advanced social structures in the animal kingdom, making them highly intelligent and strategic.

Conclusion: Nature’s Ultimate Test of Survival
Hyenas are proof that nature often prioritizes survival over comfort. Their unique reproductive anatomy, extreme birthing challenges, and dominance-driven society have allowed them to thrive despite overwhelming odds.
While their birth process remains one of the most painful and deadly in the animal kingdom, it also ensures that only the strongest females and cubs survive.
So the next time you see a spotted hyena, remember—they’re not just fierce scavengers. They’re survivors of one of evolution’s toughest reproductive challenges.
Howie Mandel opens up on his condition
On “The Kelly Clarkson Show,” Mandel discussed his struggles with mental illness. He confessed that his celebrity status had a negative impact on his mental health, not a positive one.
From the outside, he sometimes seems cheerful, but when he’s at home, especially alone, he stated that’s not the case.
When Kelly Clarkson heard this, she was shocked. Mandel then acknowledged, “I’m heavily medicated.” Clarkson found it hard to comprehend that someone would make derogatory remarks about her.

Since he was a young child, Howard Stern has battled anxiety and OCD. He has said that he has had these ailments for almost his entire life.
Because he didn’t have any classmates to make friends with when he was younger, he was labeled “strange.” Though he believes he gets paid to be strange, he now finds that every day is a struggle. America’s Got Talent has Stern on the panel as a judge.
