Some people have larger Adam’s apples than others. This is because some people develop more cartilage around the vocal cords, or they have a larger voice box. People with a larger Adam’s apple tend to have a deeper voice than people with a smaller one. That’s why women often have voices that are less deep than men.

The Adam’s apple, also called a laryngeal prominence, refers to the cartilage surrounding the thyroid and throat in the front of the neck. Although it is present at birth, it grows during male puberty or with testosterone hormone therapy. Males typically have higher testosterone levels than females, so they also usually have larger Adam’s apples.

Men develop a larger voice box than women during puberty. So a larger Adam's apple may be linked to having a deep voice. In general, excessive hormones, mainly testosterone, produced at puberty decide the size of your Adam’s apple. A woman may have a larger Adam’s apple if she has high levels of testosterone, especially during puberty.
