Do Some Women Have Adam’s Apples?

Every person, regardless of sex, has a thyroid cartilage forming the front wall of the larynx. In some women, this cartilage projects forward enough to create a visible bump on the neck, the feature commonly called an Adam’s apple. The difference between men and women is not the presence or absence of the structure but its angle and size, shaped largely by hormones during puberty. Because the range of normal variation is wide, a noticeable Adam’s apple on a woman is an anatomical variant, not a medical oddity.

What the Adam’s Apple Actually Is

The bump people call an Adam’s apple is the forward-projecting peak of the thyroid cartilage, the largest cartilage in the larynx. It sits at the front of the throat, roughly at the level of the fourth and fifth cervical vertebrae, and serves as an anchor point for the vocal cords on the inside and several strap muscles on the outside. Everyone has one. The reason it tends to be more visible in men comes down to geometry: the two plates of the thyroid cartilage meet at a sharper angle in males, pushing the peak further forward under the skin.

A CT-based study of 283 people found that the average angle where the two cartilage plates meet was about 76 degrees in males and about 94 degrees in females.¹ A smaller angle means a more pointed, protruding peak. A wider angle means a flatter, less prominent front surface. But those are averages. Some women sit at the lower end of the female range, near 91 degrees, while some men sit at the higher end of theirs. The distributions overlap, and that overlap is why some women have a bump that is easy to see and some men barely show one at all.

Why Puberty Makes the Difference

Before puberty, male and female thyroid cartilages look virtually the same. The same CT study found that in females, the angle of the cartilage plates stayed relatively constant across all age groups, hovering between about 91 and 97 degrees from childhood through adulthood. In males, the angle steadily decreased with age, dropping from around 92 degrees in young boys to about 67 degrees in adult men, with the steepest change happening in the 14-to-15-year age group.¹ That rapid reshaping is driven by testosterone surging during male puberty, which triggers the cartilage to grow forward and the vocal cords to lengthen, producing both a deeper voice and a more pronounced bump.

Because female puberty involves far less testosterone exposure, the thyroid cartilage simply does not undergo the same dramatic reshaping. It grows somewhat as the whole body grows, but it does not narrow its angle the way the male cartilage does. This means the sex difference in Adam’s apple prominence is almost entirely a post-pubertal development. Before about age 12 or 13, you would have a hard time telling male and female larynges apart on a scan.

Why Some Women’s Adam’s Apples Are More Visible

Even though women on average have a wider, flatter thyroid cartilage angle, several factors can make the structure conspicuous on the neck:

Natural cartilage variation: The female average is about 94 degrees, but individuals differ. A woman at the lower end of that range has a noticeably sharper peak than one at the higher end.
Body composition: Less subcutaneous fat over the neck means less tissue cushioning the cartilage. In very lean women, or women with naturally thin necks, the thyroid prominence sits closer to the skin surface and catches light and shadow more readily.
Neck length and posture: A longer neck stretches the skin tighter over underlying structures, and habitual head position (chin up or tilted back) can make the cartilage more visible than it would be in a neutral posture.
Hormonal profile: Women with conditions that produce higher-than-typical androgen levels, such as polycystic ovary syndrome or congenital adrenal hyperplasia, may experience some degree of laryngeal cartilage growth, although this is generally modest compared to male pubertal growth.

None of these scenarios represents a medical problem. A visible Adam’s apple in a woman is not a sign that something has gone wrong hormonally unless it appears alongside other unexpected changes, like a rapidly deepening voice or new facial hair growth, in which case the underlying hormone picture is worth investigating for its own sake.

More Than Just the Bump: How the Entire Larynx Differs

The Adam’s apple is the most visible sex difference in the larynx, but the structural divergence goes deeper than the angle of one cartilage. A study of 600 individuals found significant differences in the transverse diameters of the thyroid cartilage at multiple levels, and the vertical position of the cartilage relative to the cervical spine differed too: in women, the superior border of the thyroid cartilage most commonly sat at the C4 vertebral level, while in men it was more often at C4/5.² Men also had wider articular facets on the thyroid cartilage and longer cartilage plates overall.³

These differences matter practically in surgery (spine surgeons and ENT surgeons need to know where the cartilage sits and how big it is), but for the average reader, the takeaway is that the Adam’s apple is just the outward sign of a whole suite of size and shape differences in the voicebox. A woman who has a visible bump may still have an overall laryngeal structure that is squarely within the typical female range in every other dimension. The surface appearance tells you about one angle of one cartilage, not about the larynx as a whole.

Does a Bigger Adam’s Apple Mean a Deeper Voice?

There is a loose connection, but it is not as tight as most people assume. A larger, more protruding thyroid cartilage generally houses longer vocal cords, and longer cords vibrate at a lower frequency, producing a lower-pitched voice. In men, higher testosterone levels do weakly correlate with lower voice pitch.¹ But voice pitch is influenced by many things beyond cartilage geometry: the mass and tension of the vocal cords themselves, the shape of the vocal tract above the larynx, and learned vocal behavior all play roles.

For women specifically, a visible Adam’s apple does not reliably predict a particularly low speaking voice. A woman might have a slightly more prominent cartilage peak because of her lean build or neck anatomy while having perfectly typical vocal cord length and a voice in the usual female range. And on the flip side, some women with notably deep contralto voices have unremarkable-looking necks. The bump and the sound are related through a common anatomical framework, but one is a poor proxy for the other in any individual case.

Social Perception and Why People Notice

The Adam’s apple carries outsized social significance relative to its biological importance. Research into how people perceive the laryngeal prominence confirms what many already sense intuitively: the size of the bump strongly influences whether observers read a neck as masculine or feminine. A web-based survey study found that laryngeal prominence size meaningfully affected socially perceived gender expression, and the researchers noted that exactly how much cartilage needs to be reduced surgically to convey a feminine appearance is still not well understood.⁴

This social weight means that some cisgender women with prominent Adam’s apples report self-consciousness about the feature, especially in profile or when the neck is exposed. It also means the bump carries particular emotional weight for transgender women, for whom the prominence can be a source of gender dysphoria and a visual cue that draws unwanted scrutiny. The anatomy is identical in both cases: a slightly sharper-than-average thyroid cartilage angle sitting under thin skin. The social reading people assign to it is what varies.

Chondrolaryngoplasty, the “Tracheal Shave”

For anyone who wants to reduce the prominence of an Adam’s apple, the standard procedure is chondrolaryngoplasty, informally called a tracheal shave. The surgeon shaves down the forward-projecting cartilage to flatten the bump. It is a relatively quick outpatient operation, but it carries a specific risk that makes surgical skill critical: the vocal cords attach to the inside of the thyroid cartilage very near the peak, and removing too much cartilage can destabilize that attachment point.

In a study of 45 patients who underwent chondrolaryngoplasty, satisfaction was high and voice complications were rare. Only four patients reported any change in their voice, and three of those did not report long-term issues on follow-up.⁵ A separate study confirmed that the procedure was safe and effective in transfeminine patients, with statistically significant improvement in patient-reported quality-of-life scores after surgery.⁶ Surgeons typically use a fiberoptic laryngoscope or a needle placed through the cartilage during the operation to locate the vocal cord attachment point, ensuring they do not cut past it.⁷

When Tracheal Shaves Go Wrong

The surgery’s main risk, destabilizing the anterior commissure where the vocal cords meet, is uncommon but serious when it does happen. A chart review of 94 transfeminine women who had undergone chondrolaryngoplasty elsewhere found that about 29 percent reported chronic hoarseness, deepened pitch, or loss of their upper vocal register after the procedure. Endoscopic examination in many of these cases showed lax vocal folds, a persistent gap at the front of the cords, and in some cases outright dislocation of the anterior commissure where too much cartilage had been removed.⁸

That 29 percent figure is striking, but context matters. These were patients specifically referred to a specialty voice center for problems after surgery performed at outside facilities, so the sample is skewed toward complications by design. It does not mean that roughly a third of all tracheal shaves result in voice damage. A broader review of outcomes after gender-affirming laryngeal surgery found complications from chondrolaryngoplasty in only a small number of patients, including skin tethering, late-stage infection, and voice change.⁹ The gap between these numbers illustrates how much surgical technique and experience matter. With proper intraoperative visualization to identify the vocal cord attachment, the risk drops considerably. Without it, the risk is real and the consequences are difficult to reverse, because lowering a voice that has already been lowered by cord damage is exactly the opposite of what transfeminine patients want.

Cisgender Women Who Consider the Procedure

Although chondrolaryngoplasty is most commonly discussed in the context of gender-affirming care for transgender women, cisgender women occasionally seek the procedure too. Some have a naturally prominent thyroid cartilage and find it cosmetically bothersome, especially when their neck is exposed in profile. Others develop increased cartilage prominence after significant weight loss removes the soft tissue that previously masked it. The surgical approach is identical regardless of the reason: shave the cartilage, protect the vocal cords.

There is less published research specifically on cisgender women undergoing tracheal shaves, because the patient population is smaller and the procedure is less commonly requested. The anatomy, risks, and recovery are the same, but the starting point differs: cisgender women generally have a wider thyroid cartilage angle to begin with, which means there is less cartilage to remove and the vocal cord attachment point may be closer to the peak relative to the overall bump. A surgeon familiar with the procedure should be able to set realistic expectations about how much flattening is achievable.

An Evolutionary Puzzle

Why male humans develop such a pronounced laryngeal prominence at all is not entirely settled. One leading idea is that the enlarged, descended larynx gives men a deeper voice that signals body size and physical maturity to rivals and potential mates. The voice-lowering function of a longer vocal tract and longer vocal cords provides an acoustic advantage, and the visible bump is essentially a byproduct of the cartilage reshaping that makes the deeper voice possible.

Humans are not the only species with this pattern. Male goitred gazelles, Mongolian gazelles, and fallow deer all develop pronouncedly enlarged and descended larynges, a parallel to the human male’s Adam’s apple. Like humans, goitred gazelles are not born with a descended larynx; the sexual dimorphism develops during the animal’s life as male hormones reshape the structure.¹⁰ The fact that this pattern has evolved independently in multiple mammalian lineages suggests that the selective pressure for a larger male larynx is strong, even though it is not entirely clear whether the driving force is mate attraction, rival intimidation, or something else. Whatever the evolutionary pressures, women’s larynges did not face the same selection intensity, which is ultimately why the female thyroid cartilage angle stays relatively flat and the male angle sharpens so dramatically at puberty.

Measuring the Prominence Without a CT Scanner

Most of the research on thyroid cartilage shape has relied on CT scans or cadaver dissections, which are not exactly practical for someone at home wondering how their neck compares. Recent work has explored using simple two-dimensional photography to measure laryngeal prominence size, finding that standardized photos can reliably distinguish male from female measurements.¹¹ This kind of method has practical value for surgical planning: it gives surgeons a non-invasive way to quantify how prominent the bump is before a tracheal shave and to document how much it changed afterward. For the rest of us, it is a reminder that a feature people tend to describe in binary terms, “has an Adam’s apple” or “doesn’t have one,” actually exists on a measurable continuum, one that starts well within the range many people would never notice and extends to prominences that draw immediate attention.
