Female hyenas have a unique and challenging experience when it comes to giving birth. These fascinating creatures possess a surprising similarity to humans in this aspect. Both species struggle with the birthing process due to the large size of the newborns and the narrowness of the birth canal.
One of the most striking features of female hyenas is their exceptionally high levels of testosterone. In fact, female hyenas have three times more testosterone than their male counterparts. This hormonal imbalance leads to the development of a pseudo-penis, which serves as the birth canal for hyena cubs.
The pseudo-penis is essentially the enlarged clitoris of the female hyena. This organ is only about one inch across, making it an incredibly challenging passage for the baby hyenas to navigate during birth. With such a narrow birth canal, many cubs do not survive the labor process.
After an average gestation period of 110 days, the female spotted hyena gives birth to two to four cubs. However, the small size of the birth canal poses a significant risk to both the mother and her offspring. The cubs weigh around 1-1.5 kg and must squeeze through the 1.54 cm (1 inch) wide pseudo-penis.
The resemblance between the female hyena’s birth canal and the genitalia of male hyenas is quite remarkable. This unique adaptation is a result of the evolutionary pressures faced by hyenas, where dominance and aggression play a crucial role in their social structure.
Despite the risks and challenges associated with giving birth, female hyenas have evolved to overcome these obstacles. They possess incredible strength and endurance, which allows them to endure the labor process. Additionally, female hyenas have a high pain tolerance, further aiding them in this challenging endeavor.
Interestingly, the difficulty in giving birth is not limited to hyenas. Humans also face similar issues, with the large size of human babies and the relatively narrow birth canal of the mother. This parallel between hyenas and humans sheds light on the shared struggles and challenges faced by different species during childbirth.
Female hyenas have a unique and risky labor process due to their enlarged clitoris, which serves as the birth canal. The small size of the pseudo-penis poses a significant challenge for the delivery of hyena cubs. Despite these challenges, female hyenas have evolved remarkable strength and endurance to overcome the difficulties associated with giving birth. The similarities between hyenas and humans in this aspect highlight the shared struggles faced by different species during childbirth.
How Do Female Hyenas Give Birth?
Female hyenas have a unique and intriguing method of giving birth. Due to their high levels of testosterone, which are three times greater than those of males, female hyenas experience a rather unusual labor process. Instead of using a traditional birth canal, they give birth through their elongated clitoris, also known as a pseudo-penis.
The birth canal of a hyena is extremely narrow, measuring only about one inch in diameter. This poses significant challenges during delivery, making it a risky and difficult process. The narrow passage makes it harder for the hyena cubs to exit the mother’s body, increasing the likelihood of complications and resulting in a high mortality rate for newborns.
The peculiar anatomy and narrow birth canal of female hyenas contribute to a number of birth-related complications. These complications can include prolonged labor, difficulty in fully dilating the pseudo-penis, and even the potential for the cubs to become wedged inside during delivery. As a result, many hyena babies do not survive the birthing process.
Female hyenas give birth through their enlarged clitoris, or pseudo-penis, due to their high testosterone levels. The narrow birth canal presents significant challenges, leading to a high mortality rate for hyena cubs.
What Happens When Female Hyenas Give Birth?
When a female hyena gives birth, it typically happens after an average gestation period of 110 days. The mother hyena usually gives birth to two to four cubs, each weighing around 1-1.5 kg. The process of giving birth is quite unique in hyenas.
The female hyena’s birth canal, through which the cubs are delivered, is approximately 1.54 cm (1 inch) wide. Interestingly, the birth canal closely resembles the genitalia of male hyenas. In fact, it is the female hyena’s clitoris that serves as the birth canal.
During the birthing process, the female hyena’s clitoris enlarges and stretches to allow the passage of the cubs. This adaptation is necessary due to the female hyena’s complex genital anatomy, which includes an extended clitoris fused with the labia, forming a structure known as the pseudo-penis. This pseudo-penis is also used for urination, mating, and giving birth.
The delivery of the cubs is a challenging and potentially risky process for both the mother and the cubs. The small size of the birth canal means that the cubs must navigate a narrow passage during birth. This can result in difficulties and complications, such as cubs getting stuck or injured during the process.
Once the cubs are born, the mother hyena takes care of them and nurses them. The cubs are born with their eyes open and are relatively independent from birth. They quickly start exploring their surroundings and may even attempt to walk within hours of being born.
To summarize:
– Female hyenas give birth after an average gestation period of 110 days.
– They typically give birth to two to four cubs.
– The birth canal is approximately 1.54 cm (1 inch) wide and resembles the genitalia of male hyenas.
– The female hyena’s clitoris serves as the birth canal, which enlarges and stretches during the birthing process.
– The delivery of the cubs can be challenging and potentially risky for both the mother and the cubs.
– Once born, the mother hyena takes care of the cubs and nurses them.
Do Female Hyenas Have Difficulty Giving Birth?
Female hyenas do indeed experience difficulty when giving birth. This is primarily due to the fact that hyena newborns are larger than average and the birth passage of the female hyena is relatively small. This combination of factors creates a challenging situation for the female hyena during the birthing process.
Researchers at Berkeley have conducted studies on both humans and hyenas, and they have found a surprising similarity between the two species in terms of birthing difficulties. In both cases, females struggle with giving birth because of the large size of the newborns and the relatively small birth passage.
It is important to note that this difficulty in giving birth is not specific to all hyenas, but rather to the spotted hyena species. The spotted hyena is known for its unique reproductive system, where the females have pseudo-penises. This unusual anatomy further complicates the birthing process for female spotted hyenas.
To summarize:
– Female hyenas, specifically spotted hyenas, experience difficulty when giving birth.
– This is due to the large size of the newborns and the relatively small birth passage.
– Studies have shown a similarity between human and hyena birthing difficulties.
– The unique reproductive anatomy of spotted hyenas, with pseudo-penises, adds further complications to the birthing process.

Conclusion
Female hyenas face a unique and risky labor process due to their high levels of testosterone, which results in a larger and more challenging birth canal. This birth canal, resembling a male hyena’s genitalia, measures only about one inch across. As a result, many hyena cubs do not survive the birth. This peculiar reproductive physiology is similar to that found in humans, where females also experience difficulty giving birth due to the combination of large newborns and narrow birth passages. The discovery of this shared similarity between humans and hyenas sheds light on the fascinating world of animal reproductive biology and highlights the challenges faced by female hyenas in bringing their cubs into the world.
