The Adam’s apple typically stops growing by the end of puberty, around ages 18 to 20 in males.
The Anatomy Behind the Adam’s Apple
The Adam’s apple, medically known as the laryngeal prominence, is a noticeable lump formed by the thyroid cartilage surrounding the larynx or voice box. It’s most prominent in males due to the influence of testosterone during puberty. This cartilage protects the vocal cords and plays a vital role in voice modulation.
The thyroid cartilage grows larger and protrudes more during puberty, which causes the visible bulge commonly referred to as the Adam’s apple. While everyone has this cartilage, it is usually less noticeable in females because their thyroid cartilage remains smaller and less angled.
Hormonal Influence on Growth
Testosterone surges trigger significant changes in the larynx during puberty. This hormone causes the thyroid cartilage to grow rapidly, pushing forward and making the Adam’s apple more prominent. At the same time, the vocal cords lengthen and thicken, deepening the voice.
This growth spurt is part of broader secondary sexual characteristics that include facial hair growth, muscle development, and changes in body composition. The size increase of the Adam’s apple is directly related to these hormonal shifts.
Growth Timeline During Puberty
Puberty generally starts between ages 9 and 14 for boys. The larynx begins to enlarge noticeably around age 12 or 13. This growth continues rapidly for several years before slowing down.
By around age 18 to 20, most males have completed this phase of development, including the growth of their Adam’s apple. After this period, further enlargement is minimal or nonexistent.
Variations in Adam’s Apple Size
Not all men have equally prominent Adam’s apples. Several factors influence its size:
- Genetics: Family traits can determine how large or small your thyroid cartilage grows.
- Hormone Levels: Variations in testosterone levels affect how much growth occurs during puberty.
- Anatomy: The angle of the thyroid cartilage can vary, altering how visible the bulge appears.
Some men may have a very noticeable protrusion, while others have a subtler one that blends more smoothly with their neck contour.
The Female Perspective
Females also have thyroid cartilage but typically don’t experience significant enlargement because their bodies produce less testosterone. Their larynx grows slightly but remains smaller and less angled than in males.
This difference explains why most women lack a visible Adam’s apple or only have a slight bump that is barely noticeable.
Understanding When Does Adam’s Apple Stop Growing?
The key question—When Does Adam’s Apple Stop Growing?—centers on understanding puberty’s timeline and its effects on laryngeal development.
In general:
- The Adam’s apple begins growing at puberty onset (around ages 11-13).
- The most rapid growth occurs between ages 13-17.
- Growth slows significantly after age 17.
- The process completes by approximately age 18-20.
After this point, changes to the size of the Adam’s apple are minimal unless influenced by external factors such as surgery or trauma.
Table: Typical Growth Stages of Adam’s Apple During Puberty
| Age Range | Laryngeal Development Stage | Description |
|---|---|---|
| 9 – 12 years | Pre-puberty baseline | Larynx is small; no visible protrusion; vocal cords short and thin. |
| 12 – 15 years | Rapid growth phase | Larynx enlarges; thyroid cartilage grows; voice deepens; Adam’s apple becomes visible. |
| 15 – 18 years | Maturation phase | Larynx reaches near adult size; vocal cords lengthen; voice stabilizes; Adams apple prominent. |
| 18 – 20 years+ | Growth completion phase | Laryngeal growth slows or stops; final size mostly established; minimal changes afterward. |
The Role of Voice Changes in Growth Completion
One clear sign that your Adam’s apple has stopped growing is when your voice settles into its adult pitch. During puberty, as your larynx enlarges alongside your thyroid cartilage, your vocal cords lengthen and thicken. This results in a deeper voice that usually stabilizes around late adolescence.
If your voice has fully matured without further cracking or noticeable pitch shifts by your late teens or early twenties, it’s a strong indicator that your laryngeal structures—including your Adam’s apple—have finished growing.
Laryngeal Growth Beyond Puberty?
While major growth ends by early adulthood, subtle changes can occur due to aging or health conditions:
- Aging: The larynx may shrink slightly with age due to cartilage calcification and muscle atrophy.
- Surgical Alterations: Procedures like chondrolaryngoplasty (Adam’s apple reduction surgery) can change its size artificially.
- Disease: Certain disorders affecting hormones or cartilage might influence laryngeal structure over time.
However, none of these cause true natural growth after puberty finishes.
The Impact of Genetics Versus Hormones on Size Variations
Genetics plays a huge role in determining how large an individual’s Adam’s apple becomes. Two boys going through similar hormonal surges may still develop different-sized protrusions simply because their genetic blueprint instructs different cartilage shapes and sizes.
Hormones like testosterone act as triggers for growth but cannot override genetic predispositions entirely. This explains why some males have very pronounced Adams apples while others barely show any bulge despite similar hormone levels during puberty.
A Closer Look at Thyroid Cartilage Angles
The angle formed by two plates of thyroid cartilage largely determines visibility:
- A sharper angle (about 90 degrees) creates a more prominent bulge seen mostly in males.
- A wider angle (greater than 120 degrees) results in a smoother neck contour typical for females.
This anatomical feature is genetically determined early on but becomes more defined during puberty under hormonal influence.
Surgical Options for Modifying an Enlarged Adam’s Apple
Some individuals seek cosmetic procedures if they feel their Adam’s apple is too large or asymmetrical. The most common surgery is chondrolaryngoplasty—often called “tracheal shave.”
This procedure involves shaving down part of the thyroid cartilage to reduce its prominence without affecting vocal function significantly. It requires skilled surgeons because excessive removal risks damaging vocal cords or causing voice changes.
Surgery candidates typically are adults whose natural growth has ceased since operating on growing tissue could lead to complications or unpredictable results later on.
Surgical Considerations Table: Chondrolaryngoplasty Overview
| Factor | Description | Considerations/Outcomes |
|---|---|---|
| Surgical Goal | Reduce size/visibility of Adams apple by shaving cartilage. | Aesthetic improvement with minimal impact on voice if done properly. |
| Candidates Age Range | Generally adults post-puberty (18+ years). | Avoid surgery before completion of natural growth for safety reasons. |
| Pitfalls/Risks | Poor healing, voice changes, scar visibility. | Select experienced surgeons; weigh benefits vs risks carefully. |
The Science Behind Male Voice Deepening Correlates With Growth Completion
The deepening male voice is one hallmark signaling that physical changes like Adams apple enlargement are underway—and nearing completion. The vocal folds inside lengthen and thicken under testosterone influence while the surrounding thyroid cartilage expands outward creating that characteristic bump.
Voice pitch tends to stabilize once these changes plateau around late adolescence—roughly coinciding with when Adams apple growth stops. If you notice ongoing shifts beyond early twenties though rare—it might be worth consulting an ENT specialist for evaluation.
Differences Between Individuals Explained Through Hormonal Timing
Not all boys hit puberty at exactly the same time nor progress identically through each stage:
- Boys who enter puberty earlier tend to develop larger Adams apples sooner than peers who mature later.
- If hormonal surges extend longer or peak higher in some individuals it may cause slightly bigger laryngeal structures overall—but this effect usually caps off near adulthood regardless.
Therefore timing matters but final size mostly depends on genetics combined with total hormone exposure during those crucial teenage years.

Frequently Asked Questions
When does Adam’s apple stop growing in males?
The Adam’s apple usually stops growing by the end of puberty, around ages 18 to 20 in males. This is when the thyroid cartilage completes its rapid growth phase triggered by testosterone during adolescence.
When does Adam’s apple growth begin during puberty?
Growth of the Adam’s apple typically begins around ages 12 to 13 in boys. This marks the start of the larynx enlargement influenced by hormonal changes, especially increased testosterone levels.
When does Adam’s apple stop growing compared to other puberty changes?
The Adam’s apple growth generally finishes alongside other secondary sexual characteristics by ages 18 to 20. After this period, further enlargement is minimal or does not occur.
When does Adam’s apple stop growing in females?
In females, the Adam’s apple remains small and less prominent because their bodies produce lower testosterone levels. The thyroid cartilage grows only slightly and stops early, often during early adolescence.
When does Adam’s apple size variation occur during growth?
The size variation of the Adam’s apple happens during puberty due to genetics, hormone levels, and cartilage anatomy. These factors influence how much it grows and how visible it becomes before growth stops around age 20.
Conclusion – When Does Adam’s Apple Stop Growing?
To wrap it up clearly: The Adam’s apple stops growing once puberty concludes—usually between ages 18 and 20 for most males. This timeline aligns closely with when testosterone-driven laryngeal development finishes and voice pitch stabilizes into adulthood levels.
Natural variations exist depending on genetics and hormone levels but major size increases beyond early adulthood are rare unless medical intervention occurs. Understanding this helps demystify why some men sport pronounced Adams apples while others don’t—and reassures those wondering about ongoing neck changes well past their teenage years.
