You've probably noticed it while someone is mid-sentence or swallowing a gulp of water. That little protrusion in the neck that bobs up and down. It's common knowledge that guys have them and girls don't, right? Well, sort of.
The truth is actually a bit more nuanced than what we learned in middle school biology. Everyone—literally everyone—has the anatomical structures that make up an Adam’s apple. If you didn't, you wouldn't be able to talk, breathe properly, or protect your airway. The real question isn't why men have them, but rather why they are so much more visible in men than in women. It comes down to a mix of testosterone, cartilage angles, and the sheer physics of sound.
What is an Adam’s Apple, Anyway?
Let's clear the air. The "Adam's apple" isn't a bone. It isn't a weird growth. It's a chunk of bony cartilage called the laryngeal prominence. This cartilage sits right in front of your larynx, which is your voice box. Think of it like a shield. Its primary job is to wrap around your vocal cords and protect them from getting smashed or injured.
During puberty, the body goes through a massive chemical overhaul. For boys, a surge of testosterone causes the larynx to grow significantly larger than it does in girls. As the larynx expands, the thyroid cartilage (the shield) has to grow to accommodate it. Because the neck is only so wide, that cartilage has nowhere to go but forward.
The Angle of the Dangle (Literally)
Here is where the visual difference kicks in. It isn't just about size; it's about the geometry of your throat. In women, the two plates of the thyroid cartilage meet at a very wide angle—usually around 120 degrees. This creates a soft, rounded surface that stays flush with the neck. You can't see it because it’s basically a gentle curve.
Men are different. Their cartilage plates meet at a much sharper, more acute angle—typically around 90 degrees.

Imagine a house roof. A flat, shallow roof is barely noticeable from the street. But a steep, 90-degree peak sticks right out. That’s why do men have adam's apples and women don't in the visual sense. The male larynx juts out like a prow of a ship. It’s the same hardware, just installed at a different setting.
Do Women Have Adam’s Apples?
Yes. They do. Honestly, if a woman didn't have that cartilage, her vocal cords would be exposed and her airway would be unstable. If you’re a woman and you tilt your head back and feel your throat, you’ll feel a slight bump. It’s there.
However, some women have more prominent Adam's apples than others. This can be due to genetics, a naturally larger larynx, or even just having a very lean neck where the underlying structures are more visible. There’s also the factor of hormonal imbalances. If a woman has high levels of testosterone during puberty (conditions like PCOS can sometimes play a role here, though it's usually more about individual genetic blueprints), her larynx might grow larger than average, leading to a visible bump.
It’s also worth noting that some men have very small, barely visible Adam's apples. Body fat percentage plays a huge role here. If a guy has a bit more tissue around the neck, it can completely camouflage the larynx.
The Voice Connection: Why the Bump Matters for Sound
There is a functional reason for all this growth. It isn't just for show. The size of the larynx directly dictates the pitch of the voice.

Think of a guitar. The thick, long strings produce those deep, rattling bass notes. The thin, short strings produce the high-pitched chirps. When a boy's larynx grows during puberty, his vocal cords also grow longer and thicker. To house these longer "strings," the "instrument case" (the larynx) has to get bigger.
This is why a visible Adam's apple is almost always synonymous with a deeper voice. The bigger the bump, the bigger the resonating chamber. When women’s voices drop slightly during puberty, the growth is minimal compared to the explosive change in males, which is why their "instrument case" stays small and hidden.
Common Misconceptions and Weird Myths
We’ve all heard the story. The name comes from the Garden of Eden—the idea being that a piece of the forbidden fruit got stuck in Adam’s throat. It’s a great story, but it’s just folklore. In reality, the term likely stems from a mistranslation of the Hebrew phrase tappuach ha'adam, which means "male bump" or "human bump."
Another myth? That the size of an Adam's apple correlates to "manliness" or virility. Science says no. While testosterone triggers the growth, the final size is mostly down to your DNA. A guy with a massive Adam's apple isn't necessarily "more of a man" than a guy with a smooth neck; he just has a specific cartilage configuration.
Can You Change It?
In the modern world, the visibility of the Adam's apple is a major focal point for gender-affirming surgeries. For trans women or non-binary individuals, a procedure called a Chondrolaryngoplasty (more commonly known as a "tracheal shave") can reduce the size of the bump. A surgeon literally shaves down the thyroid cartilage to create a smoother neck profile.

On the flip side, some people opt for implants to increase the prominence of the Adam's apple to achieve a more traditionally masculine look.
Practical Insights and Health Checks
While a visible bump is usually just a normal part of anatomy, there are times when you should pay attention to it. If you suddenly notice a new lump in your neck that wasn't there before, or if your Adam's apple area feels tender, it might not be your larynx at all.
- Thyroid Issues: The thyroid gland sits just below the Adam's apple. If it becomes inflamed or develops a goiter, it can look like a secondary bump.
- Cysts: Thyroglossal duct cysts can form in the midline of the neck.
- Lymph Nodes: Swollen nodes from an infection can sometimes be mistaken for laryngeal cartilage.
If the bump moves when you swallow, it’s likely your Adam's apple. If it stays still or feels "stuck" to the skin, get it checked by a doctor.
To summarize the whole "why do men have adam's apples and women don't" debate: everyone has the hardware, but men have the "heavy-duty" version. It's a byproduct of a deepening voice and a sharper angle of cartilage growth during the teenage years. It’s a shield for your voice, a marker of puberty, and a fascinating quirk of human geometry.
Next time you see one, just remember it’s basically a built-in protective case for the most sophisticated musical instrument on earth—the human voice.
Actionable Steps for Throat Health:
- Hydrate: Your vocal cords (housed inside that Adam's apple) need moisture to vibrate efficiently.
- Posture Matters: Slouching can compress the larynx area, leading to vocal strain.
- Self-Exam: Occasionally feel the area around your larynx. Familiarize yourself with what is "normal" for your neck so you can spot unusual lumps early.
- Voice Rest: If your voice is raspy, your larynx is likely inflamed. Pushing through it can cause long-term thickening of the cords.
