The Adam’s apple—medically referred to as the laryngeal prominence—is the visible bump located at the front of the throat. It is formed by the thyroid cartilage, a firm yet flexible structure that surrounds and protects the larynx, commonly known as the voice box. Although the Adam’s apple is most often associated with men, it is important to note that everyone has this structure. The difference lies in how prominent it appears, which varies widely from person to person.
The term “Adam’s apple” originates from folklore rather than science. According to a traditional biblical legend, a piece of forbidden fruit became lodged in Adam’s throat, leaving a permanent bulge. While this story has no anatomical basis, it gave rise to a name that remains widely used today. In reality, the Adam’s apple is a normal and essential part of human anatomy shared by all sexes.
What Is the Function of the Adam’s Apple?
The primary role of the thyroid cartilage is protection. It acts as a shield for the vocal cords housed within the larynx, helping prevent damage from physical impact, pressure, or external trauma. Without this protective cartilage, the vocal folds would be significantly more exposed and vulnerable to injury.
In addition to protection, the Adam’s apple plays an indirect but important role in voice development. During puberty—particularly in individuals assigned male at birth—the thyroid cartilage tends to grow larger and tilt forward more noticeably. This growth causes the vocal cords to lengthen and thicken, which lowers voice pitch. Although the Adam’s apple itself does not generate sound, its size and angle influence the physical structure of the larynx, shaping how the voice sounds.
Development of the Adam’s Apple
At birth and during early childhood, the thyroid cartilage is present but typically small and barely visible. During puberty, hormonal changes—especially increased testosterone—stimulate rapid growth of the larynx and its surrounding cartilage in males. This growth is what causes the Adam’s apple to become more prominent.
In females, lower levels of testosterone usually result in less dramatic growth of the laryngeal cartilage. As a result, the Adam’s apple often remains subtle or difficult to see, which can create the misconception that women do not have one. Anatomically, however, the structure exists in everyone regardless of sex.
Why Adam’s Apples Differ in Size and Appearance
The prominence of the Adam’s apple varies significantly among individuals due to several factors:
-
Genetics: Inherited traits influence the size, shape, and angle of the thyroid cartilage
-
Hormonal influences: Natural hormone levels or hormone therapy can affect cartilage growth
-
Neck anatomy: Fat distribution, muscle tone, and overall neck structure play a role in visibility
-
Age: Over time, cartilage can stiffen or partially calcify, subtly changing its appearance
Because of these factors, some men have very prominent Adam’s apples while others have barely noticeable ones. Likewise, some women may have a visible laryngeal prominence depending on their unique anatomy.
Discomfort or Pain Around the Adam’s Apple
The Adam’s apple itself is made of cartilage and rarely causes pain. When discomfort occurs in that area, it is usually related to surrounding tissues or underlying conditions rather than the cartilage itself.
Common causes of discomfort include:
-
Muscle tension: Poor posture, prolonged phone use, or neck strain can cause tightness or soreness
-
Throat irritation: Anxiety, allergies, acid reflux, or excessive voice use may create a sensation of pressure
-
Thyroid issues: The thyroid gland lies just below the cartilage, so inflammation or nodules may cause pain or swelling
-
Infections: Conditions such as laryngitis or throat infections can make swallowing uncomfortable
-
Less common causes: Persistent pain, a growing lump, unexplained voice changes, or difficulty breathing should be evaluated by a medical professional
Any symptoms that worsen, persist, or interfere with swallowing or breathing warrant medical attention.
Cosmetic and Surgical Considerations
For some individuals, the appearance of the Adam’s apple can cause distress, particularly for cosmetic or gender-affirming reasons. A surgical procedure known as chondrolaryngoplasty, often called a tracheal shave, can reduce the projection by carefully trimming excess thyroid cartilage.
Advancements in surgical techniques have led to options such as transoral chondrolaryngoplasty, which is performed through the mouth and leaves no visible external scar. While these procedures are generally safe when performed by experienced surgeons, they are not without risks. Potential complications include voice changes or vocal cord injury, making thorough consultation and careful consideration essential.
Final Thoughts
The Adam’s apple is a normal and functional anatomical feature that plays a vital role in protecting the vocal cords and influencing voice characteristics. Its size and visibility vary widely and are shaped by genetics, hormones, and individual anatomy. In most cases, it causes no problems, but pain, swelling, or voice changes near the area may indicate an underlying condition that deserves medical evaluation.
By understanding what the Adam’s apple is—and what it is not—people can better appreciate their own anatomy, reduce unnecessary worry, and make informed decisions about health, appearance, and personal comfort.
