Does Testosterone Lower Your Voice?


Testosterone is a hormone that plays a crucial role in the development of secondary sexual characteristics in males. It is responsible for various changes that occur during puberty, including the deepening of the voice. Many people often wonder whether testosterone can actually lower your voice. In this article, we will delve into the science behind this phenomenon and address some commonly asked questions regarding testosterone and vocal changes.

Understanding Testosterone and Voice:

1. The Role of Testosterone in Puberty:

During puberty, testosterone levels increase in males, triggering a series of physical changes. One of the most noticeable changes is the deepening of the voice. This occurs due to the growth and elongation of the vocal cords, which are stimulated by testosterone. The increase in testosterone causes the vocal cords to thicken and lengthen, leading to a lower-pitched voice.

2. How Testosterone Affects Vocal Cords:

Testosterone affects the vocal cords by promoting the growth of vocal fold tissues. These tissues become thicker and longer, resulting in a lower fundamental frequency of the voice. The fundamental frequency refers to the rate at which the vocal cords vibrate, determining the pitch of the voice. Testosterone also influences the development of the larynx, commonly known as the voice box, which further contributes to the deepening of the voice.

3. Timing of Vocal Changes:

The timing of vocal changes varies from person to person, as everyone experiences puberty at different rates. Typically, males begin to experience voice deepening around the age of 13 to 15. The process usually continues for a couple of years until the voice stabilizes at its adult pitch. It’s important to note that the extent of vocal changes can depend on individual factors such as genetics and hormone levels.

4. Transgender Individuals and Voice Changes:

For transgender individuals undergoing hormone replacement therapy (HRT) to align their physical characteristics with their gender identity, testosterone plays a significant role in voice changes. Transgender men (assigned female at birth) who take testosterone may experience a deepening of their voice over time. However, it’s essential to note that the extent of vocal changes can vary, and some individuals may choose to explore vocal training techniques to further modify their voice.


1. Will taking testosterone automatically lower my voice?

No, taking testosterone does not automatically lower your voice. Voice changes occur gradually over time as a result of increased testosterone levels. The extent of vocal changes can also vary from person to person.

2. How long does it take for testosterone to affect my voice?

The timing of voice changes can vary, but typically, individuals may begin to notice changes within a few months to a year of starting testosterone therapy. However, it’s important to remember that everyone’s journey is unique, and patience is crucial.

3. Can I deepen my voice without taking testosterone?

Yes, there are various vocal training techniques available that can help individuals deepen their voice without taking testosterone. These techniques focus on proper vocal cord control, resonance, and pitch modulation. Working with a speech therapist or vocal coach experienced in transgender voice training can be beneficial.

4. Are voice changes permanent?

Yes, once the vocal cords have undergone changes due to testosterone, the effects are generally permanent. However, it’s important to note that individual factors such as genetics and hormone levels can influence the extent of vocal changes.

5. Can testosterone make my voice sound exactly like a cisgender male’s voice?

While testosterone can deepen the voice, it cannot guarantee an exact match to a cisgender male’s voice. Cisgender males naturally undergo voice changes during puberty, which involves a complex interplay of various biological factors. However, with vocal training and practice, individuals can achieve a voice that aligns more closely with their gender identity.


Testosterone does play a significant role in lowering the voice during puberty and for transgender individuals seeking voice changes. The hormone promotes the growth of vocal cord tissues, resulting in a lower fundamental frequency and a deeper voice. However, it’s important to understand that voice changes occur gradually and can vary from person to person. For those who do not wish to take testosterone, vocal training techniques can be explored to achieve desired voice modifications. Remember, everyone’s journey is unique, and it’s essential to find the path that aligns with your individual needs and goals.
