Among all wild animals, few experiences match the agony of a spotted hyena giving birth. Nature gave this predator unmatched strength — but also one of the most painful and dangerous deliveries in the animal kingdom.
The strange anatomy of female hyenas
Female spotted hyenas are unique. Unlike most mammals, they give birth through a pseudo-penis — a narrow canal that’s actually an extended clitoris. This passage is barely one inch wide, yet hyena cubs are born large, weighing up to 1.5 kilograms.
This design makes childbirth extremely painful. For many first-time mothers, the pressure tears the canal, causing deep injuries and often death.
Why evolution made it so risky
So why would evolution choose such a dangerous path? The answer lies in dominance and survival.
Female hyenas are more dominant than males. They have high testosterone levels, giving them powerful builds and aggressive personalities that help them rule their clans. But this hormonal boost also affects their reproductive anatomy, creating the pseudo-penis and all its challenges.
It’s a brutal trade-off — strength and control in exchange for a lifetime of dangerous births.

The grim reality of hyena births
For a first-time mother, the odds are harsh. Around 60% of cubs die during birth, often suffocated in the narrow canal. Some mothers also die from complications. Those who survive carry scars for life.
However, once a female has given birth successfully, the following deliveries become easier. The canal stretches and heals, reducing the risk in later pregnancies.
Comparing hyena births to other animals
Other large mammals — such as elephants, rhinos, and giraffes — face long labors, but not the same anatomical nightmare.
Hyenas stand alone in this suffering. Scientists often describe their birth process as the most painful and dangerous among mammals, a harsh reminder that nature’s balance can come with heavy costs.
Nature’s harsh design
Despite the pain, hyenas thrive across Africa. Their intelligence, teamwork, and adaptability keep them among the most successful predators in the wild. But their birth story remains one of evolution’s most striking paradoxes — strength born through suffering.
Q&A About Hyena Births
Q: Do hyenas really give birth through the same organ they mate with?
Yes. Female spotted hyenas give birth through an elongated clitoris, also known as a pseudo-penis.
Q: Why don’t hyenas evolve an easier way to give birth?
Their dominant behavior and high hormone levels are tied to their anatomy. Evolution favored dominance, not comfort.
Q: Do all cubs die during birth?
No, but around 60% of first-born cubs die due to suffocation or tearing of the canal. Later births are often safer.
Q: Is this painful for the mother?
Extremely. The narrow canal causes immense pain and can lead to fatal injuries during the first delivery.
Q: Which animal has the most painful birth overall?
Among mammals, spotted hyenas top the list for the most painful and dangerous births known to science.
