Many owners of Hermann’s tortoises wonder whether their pet is a male or female. Knowing the gender of your tortoise is important for its care, behavior, and future needs. This article will help you tell the difference using clear and simple signs.
Why You Should Know Your Tortoise’s Gender
Better care and understanding
Knowing if your tortoise is male or female helps you understand its behavior. Males and females act differently, especially during the breeding season.
Breeding reasons
If you plan to breed your tortoise or avoid unwanted eggs, knowing the gender is necessary.
Health differences
Females can lay eggs even without a male. If you don’t know your tortoise is female, you might miss signs of egg binding, a serious health problem.
When Can You Tell the Gender of a Hermann’s Tortoise?
Age matters
It is hard to tell the gender of a baby or young tortoise. Most signs are clear only when the tortoise is at least 4 to 6 years old or has reached about 10 cm in shell length.
Wait for maturity
Full sexual maturity usually happens around 5 to 7 years. You may need to be patient to get an accurate answer.
Physical Signs of a Male Hermann’s Tortoise
Longer tail
Males usually have longer, thicker tails. The tail often points sideways and is tucked tightly to the body.
V-shaped anal notch
The space near the tail, called the anal notch, is wider and forms a more open “V” shape in males.
Concave plastron
The bottom shell, or plastron, is slightly curved inward in males. This helps them mount females during mating.
Body size and shape
Males are often slightly smaller than females but have longer legs and claws. Their bodies are also more slender.
Physical Signs of a Female Hermann’s Tortoise
Shorter, smaller tail
Females have shorter, thinner tails. The tail points straight down and is less tightly tucked.
U-shaped anal notch
The anal notch is usually smaller and forms a more rounded “U” shape in females.
Flat or slightly convex plastron
The plastron in females is flat or may even bulge out a bit. This makes room for eggs inside the body.
Broader shell
Female tortoises have a wider and rounder shell to carry eggs more easily. They may also appear heavier and bulkier.
Behavior Differences Between Males and Females
Territorial behavior
Male Hermann’s tortoises are more likely to fight or chase other males. They can be more aggressive.
Mating behavior
Males may bob their heads, bite, or ram into females during mating attempts.
Nesting behavior
Females may dig holes or seem restless when they are ready to lay eggs. This usually happens in spring or summer.
Step-by-Step Guide to Check Your Tortoise’s Gender
Step 1: Let the tortoise grow
Wait until the tortoise is about 10 cm or more in length. This is usually the age when sex differences become clear.
Step 2: Look at the tail
Gently lift the back of your tortoise and look at the tail. Is it long and thick, or short and narrow?
Step 3: Check the plastron
Place the tortoise on its back or gently lift it to see the bottom shell. Is it curved in or flat?
Step 4: Observe the anal notch
Look at the opening near the tail. Does it form a wide V or a rounded U?
Step 5: Watch for behavior
Pay attention to aggressive or nesting behavior. These can give more clues about the gender.
Can a Vet Help?
Yes, if you are unsure
A reptile vet can examine your tortoise and give a confident answer. They may use x-rays or other tools if needed.
Useful during health checks
A vet visit is also a good time to check for other health issues. Female tortoises may need help laying eggs.
Common Mistakes When Checking Gender
Looking too early
Many people try to tell the gender when the tortoise is still young. This often leads to errors.
Only checking one feature
It is best to look at many features. Don’t rely only on tail length or shell shape.
Ignoring behavior signs
Behavior can add helpful clues, especially if physical signs are unclear.
What If You Still Can’t Tell?
Wait and watch
If you are still unsure, wait a few more months or years. The signs will become clearer over time.
Compare with others
If you have more than one Hermann’s tortoise, compare them side by side. Differences in tail and shape may be easier to spot this way.
Do Males and Females Need Different Care?
Mostly the same
Both males and females need a balanced diet, UV light, heat, space, and clean water.
Special needs for females
Females may lay eggs and need a safe place to dig. Even without mating, they can produce eggs.
Special needs for males
Males may become aggressive. They may need more space or separation from other males during mating season.
What Happens If You House Males and Females Together?
Possible mating behavior
Males may try to mate, even if females are not ready. This can stress the female.
Egg-laying risk
If mating occurs, the female may lay fertile eggs. Be ready for baby tortoises or separate them.
Consider separate enclosures
Some owners keep males and females in different pens to reduce stress and unwanted mating.

Conclusion
Telling the gender of your Hermann’s tortoise takes time, patience, and observation. Look at the tail, plastron, anal notch, and behavior. It’s easier to tell once the tortoise is mature. If you are still not sure, ask a vet. Knowing the gender will help you give better care and understand your tortoise more deeply.
