Does Testosterone Lower Your Voice?


Testosterone is a hormone that plays a crucial role in the development and maintenance of various bodily functions in both men and women. One interesting aspect of testosterone’s influence is its effect on the vocal cords, which can lead to changes in the pitch and tone of the voice. In this article, we will explore the relationship between testosterone and the lowering of the voice, as well as answer some frequently asked questions about this topic.

Understanding Testosterone and Voice Changes:

Testosterone is primarily known as a male sex hormone, but it is present in both males and females, although in different amounts. It is responsible for the development of secondary sexual characteristics in males, such as deepening of the voice, growth of facial and body hair, and muscle mass. During puberty, when testosterone levels increase significantly, boys experience voice changes that result in a deeper, more mature voice.

The Effect of Testosterone on the Vocal Cords:

The vocal cords, also known as vocal folds, are located inside the larynx (voice box) and are responsible for producing sound when air passes through them. Testosterone affects the vocal cords by causing them to lengthen and thicken. This lengthening and thickening of the vocal cords results in a lower pitch and a deeper voice. The changes in voice brought about by testosterone are irreversible, meaning that once the vocal cords have undergone these changes, the voice will permanently remain at a lower pitch.

Voice Changes in Transgender Men:

For transgender men who are undergoing hormone therapy, testosterone plays a significant role in achieving a more masculine appearance, including vocal changes. Many transgender men seek testosterone therapy to deepen their voices and align them with their gender identity. However, it is important to note that the extent of voice changes experienced by transgender men may vary. Factors such as age, genetics, and individual vocal cord structure can influence the degree to which a person’s voice can be deepened through hormone therapy.

Frequently Asked Questions:

Q: Does testosterone affect everyone’s voice in the same way?
A: No, the effect of testosterone on the voice can vary from person to person. Factors such as genetics and individual vocal cord structure can influence the degree of voice changes experienced.

Q: Can testosterone therapy change the voice of transgender women?
A: Testosterone therapy is not typically used as a method to change the voice of transgender women. Voice feminization techniques, such as speech therapy and vocal exercises, are more commonly employed to achieve desired voice changes in transgender women.

Q: Are voice changes permanent once testosterone therapy is initiated?
A: Yes, the voice changes induced by testosterone therapy are permanent. Once the vocal cords have lengthened and thickened, resulting in a lower pitch, the voice will remain at that lower range.

Q: How long does it take for testosterone to affect the voice?
A: Voice changes induced by testosterone therapy typically occur gradually over several months to a couple of years. The exact timeline can vary depending on individual factors.

Q: Are there any side effects associated with voice changes caused by testosterone?
A: Voice changes caused by testosterone therapy are generally considered a desired effect for those seeking a deeper voice. However, as with any medical intervention, there can be potential side effects. It is essential to consult with a healthcare professional before starting hormone therapy.

Q: Can voice training be combined with testosterone therapy to achieve desired voice changes?
A: Yes, many transgender men opt for voice training in addition to testosterone therapy to further enhance their vocal changes. Voice training can help individuals develop speech patterns, resonance, and other techniques to achieve a more masculine voice.


Testosterone has a profound impact on the voice, causing the vocal cords to lengthen and thicken, resulting in a deeper, more resonant tone. This effect is especially significant during puberty when boys experience natural voice changes. For transgender men, testosterone therapy can aid in achieving a more masculine voice, although the extent of voice changes can vary. It is crucial for individuals considering hormone therapy to consult with healthcare professionals who specialize in transgender care to discuss the potential effects and ensure a safe and informed decision-making process. Remember, your voice is unique, and any changes should align with your personal goals and identity.
