Walk into any high school biology class and you’ll likely hear the same old story. Boys get a bump in their neck, their voices drop an octave, and suddenly they’re dealing with this protruding lump of cartilage we call an Adam’s apple. Girls, meanwhile, seem to have perfectly smooth necks. It’s one of those "obvious" physical differences we just accept as fact.
But here’s the thing. The idea that women don't have an Adam’s apple is actually a total myth.
Seriously. If you’re a woman, reach out and touch the front of your throat. Swallow. You feel that hard structure moving up and down under your skin? That’s your larynx. And that, fundamentally, is what an Adam’s apple is. Every single human being born with a standard respiratory system has one. The difference isn't about presence or absence; it's about the angle of the dangle. Or, more accurately, the degree of the "laryngeal prominence."
The Anatomy of a Myth: Why Don't Women Have an Adam's Apple (Visible Ones, Anyway)?
To understand why women’s Adam’s apples are usually "stealth," we have to look at how the larynx—your voice box—actually grows. During puberty, a surge of testosterone in males causes the larynx to grow significantly larger. This isn't just for show. As the box grows, the vocal cords inside get longer and thicker. Think of it like a guitar string. A thick, heavy string vibrates slower and creates a deeper sound than a thin, tight one.
Because the male larynx expands so much, the two plates of thyroid cartilage that form the front of the housing have to meet at a much sharper angle. In most men, this angle is around 90 degrees. That sharp point creates the physical bump that pushes against the skin.
In women, the story is different. Estrogen doesn't trigger that same massive growth spurt in the neck. The female larynx stays smaller, and the plates of cartilage meet at a much wider, more obtuse angle—usually around 120 degrees. It’s a gentle curve rather than a sharp point. So, while the cartilage is definitely there protecting your vocal cords, it doesn't poke out. It stays tucked away, smooth and unassuming.

It's Not Just About Testosterone
It’s easy to blame (or credit) hormones for everything, but genetics plays a massive role too. You’ve probably noticed some men have massive, jagged Adam's apples, while others have necks as smooth as a marble statue. Similarly, some women naturally have a more prominent laryngeal notch.
I’ve seen plenty of women who are perfectly healthy and cisgender but have a visible bump in their throat. This can be due to a naturally thin neck, a specific genetic predisposition for larger cartilage, or even just the way their neck is contoured. It’s also important to note that what people think is an Adam’s apple in a woman isn't always the larynx. Sometimes it’s a thyroid nodule or an enlarged thyroid gland (goiter). If a woman suddenly notices a new bump appearing where there wasn't one before, that’s not her "growing an Adam’s apple"—that’s a reason to go see an endocrinologist.
The Biblical Name and the Scientific Reality
The term "Adam’s apple" actually has zero basis in medical science. It’s a colloquialism rooted in the folk tale that a piece of the forbidden fruit got stuck in Adam’s throat in the Garden of Eden. Scientifically, we call it the laryngeal prominence.
Medical professionals don't really care about the bump itself unless it’s causing issues. In the world of laryngology, the focus is on function. Dr. Robert Sataloff, a renowned ear, nose, and throat specialist, often points out that the size of the prominence is a secondary characteristic. What matters is the tension, length, and health of the vocal folds inside.
Interestingly, the size of the Adam’s apple has a direct impact on the "resonance" of the voice. This is why many trans women or non-binary individuals seek out a procedure called a tracheal shave (chondrolaryngoplasty). By surgically shaving down the thyroid cartilage, they can create a more traditionally feminine neck profile. Conversely, some trans men find that testosterone therapy naturally increases the size of their larynx, though it rarely creates a prominence as large as those who went through male puberty in their teens.

The Role of Body Fat and Neck Length
Why do some people’s Adam’s apples seem to disappear and reappear? It often comes down to body composition. Since the laryngeal prominence sits just under the skin, a layer of subcutaneous fat can easily mask it.
If someone loses a significant amount of weight, their Adam’s apple might suddenly seem "huge." It didn't grow; the "padding" around it just went away. Also, people with longer, thinner necks tend to have more visible laryngeal structures. Someone with a shorter neck or a more muscular "trapezius" area might have a larynx that is physically deeper in the neck, making it invisible regardless of its size.
When the Bump Isn't an Adam's Apple
We need to talk about the "imposters." If you are a woman and you see a lump in your neck, don't just assume you have a "manly" larynx. There are several medical conditions that can mimic this look:
- Thyroid Cysts: These are fluid-filled sacs that can develop in the thyroid gland.
- Goiters: An enlargement of the thyroid gland, often caused by iodine deficiency or Hashimoto's disease.
- Thyroglossal Duct Cysts: A fibrous cyst that forms from a leftover pocket of tissue from when the thyroid was developing in the womb.
- Lymph Nodes: Swollen lymph nodes due to infection can sometimes sit high enough to look like a laryngeal bump.
Basically, if the bump moves when you swallow and has been there since you were twenty, it’s probably just your anatomy. If it’s firm, fixed, or growing, it’s a medical query.
The Evolutionary "Why"
Evolutionary biologists have some theories about why males developed this prominent feature. One prevailing idea is sexual selection. Much like a lion’s mane or a peacock’s tail, a deep, resonant voice—aided by a larger larynx—might have historically signaled strength, maturity, and fitness to potential mates.

However, humans are complex. A deep voice isn't the only marker of "masculinity," and a smooth neck isn't the only marker of "femininity." We see massive variation across all populations. Some of the most iconic female singers have lower "contralto" ranges, implying larger vocal structures, yet they don't necessarily have a visible Adam's apple.
Practical Insights and Next Steps
If you’ve been worried about the shape of your neck or wondering why yours looks different from your friends, here’s the bottom line. Physical traits exist on a spectrum. Having a visible Adam’s apple as a woman doesn't mean your hormones are "off" or that you’re less feminine. It’s just how your cartilage is angled.
Here is what you should actually do if you’re concerned:
- Perform a self-check: Stand in front of a mirror and swallow. Watch how the structures in your neck move. A normal larynx will move up and then back down smoothly.
- Check for symmetry: Most laryngeal prominences are centered. If you have a lump that is significantly off to one side, that’s usually a sign it’s a lymph node or a thyroid issue, not your "Adam’s apple."
- Track changes: Is the bump getting bigger? Is your voice becoming persistently hoarse? If you notice vocal changes alongside a visible bump, schedule an appointment with an ENT (Ear, Nose, and Throat) doctor. They can use a tiny camera called a laryngoscope to see exactly what’s going on inside.
- Understand your "Normal": Look at photos of your female relatives. Often, neck structure is hereditary. If your mom or aunt has a similar neck shape, it’s likely just your genetic blueprint at work.
The "why don't women have an Adam's apple" question is built on a false premise. They do. It’s just built for a different acoustic profile. Stop worrying about the bump and focus on the health of the voice it protects. Whether your larynx is a sharp 90-degree angle or a soft 120-degree curve, it’s doing the heavy lifting of allowing you to speak, breathe, and sing every single day.
