The Basics of Testosterone 

Testosterone, often associated with masculinity, is more than just a contributor to male sexual development. It’s a key player in a range of bodily functions for both men and women. 

Definition and Role of Testosterone in the Human Body 

Testosterone is a steroid hormone primarily produced in the testes in men and the ovaries in women, with a small amount also made in the adrenal glands.

In men, it’s responsible for the development of male reproductive tissues, the increase in muscle and bone mass, and the growth of body hair. In women, while present in smaller amounts, testosterone is crucial for ovarian function, bone strength, and sexual well-being. 

This hormone also plays a vital role in general health, influencing mood, energy levels, and cognitive function. Its impact extends to various aspects of physical and mental health, making it a hormone of significant interest in both medical and psychological fields. 

Differences in Testosterone Levels Between Genders 

The levels of testosterone naturally vary between genders. Men typically have higher levels of testosterone, with the average range being about 300 to 1,000 ng/dL (nanograms per deciliter), while women have lower levels, usually ranging from 15 to 70 ng/dL.

This difference in testosterone levels is what primarily drives the distinct physical characteristics between men and women, including muscle mass and body hair distribution. 

However, it’s important to note that the level of testosterone in the body isn’t constant; it can fluctuate due to various factors such as age, health, and lifestyle.

For instance, testosterone levels in men peak during adolescence and early adulthood and gradually decrease with age. 

Does Testosterone Change Your Voice? 

Testosterone plays a crucial role in voice development. During puberty, testosterone levels surge in males, leading to various physical changes, including voice deepening. This occurs because testosterone causes the vocal cords to thicken and lengthen, resulting in a lower pitch. The larynx, or voice box, also grows, further contributing to the voice’s deeper quality.  

A recent study published in the Journal of Frontiers in Psychology finds significant associations between vocal characteristics and reproductive advantage factors such as sex hormones, body size, and physical strength.

It suggests a complex interplay between these elements and vocal traits, indicating the need for more comprehensive future research in diverse areas to fully understand the evolutionary significance of voice modulation. (1) 

Testosterone And Voice Pitch

Testosterone is primarily known as the male sex hormone, but it’s present in both males and females, albeit in different concentrations. T. hormone has diferent effects on vocal cards and voice pitch of men and women.

In males, testosterone is responsible for the deepening of the voice during puberty. This process begins when the hormone triggers the growth and thickening of the vocal cords, resulting in a lower pitch. The size and shape of the larynx (voice box) also changes, becoming larger, which contributes to the resonance and depth of the voice. 

In females, testosterone is present in smaller amounts and has a less pronounced effect on the voice. However, it still plays a role in maintaining vocal cord health and function. 

Testosterone And Loss of Voice 

Testosterone itself is not typically associated with causing a loss of voice. However, there are some indirect ways in which testosterone levels might be related to changes in the voice, though not usually resulting in complete voice loss.

Here are a few considerations: 


During puberty, especially in males, increased levels of testosterone lead to changes in the voice, such as deepening. This process can sometimes cause temporary voice instability or cracking, but it does not lead to a loss of voice. 

Vocal Cord Health

Testosterone plays a role in maintaining muscle mass and tissue health, including that of the vocal cords. Low testosterone levels might potentially affect the quality of the voice or its strength, but again, this is not typically associated with complete voice loss. 

Testosterone Therapy

In transgender men or individuals undergoing testosterone therapy, the hormone can cause the vocal cords to thicken and lengthen, leading to a deeper voice. While this is a significant change, it is not the same as losing one’s voice. 

Underlying Health Conditions

Certain health conditions that affect testosterone levels might also impact the voice. For example, conditions that affect the endocrine system or the larynx can lead to voice changes. However, these changes are usually due to the underlying condition rather than the testosterone level itself. 

Voice Strain or Misuse

If an individual is adjusting to a new, deeper voice due to increased testosterone (such as during puberty or hormone therapy), they might inadvertently strain their voice. This strain can lead to temporary hoarseness or voice loss, but it’s usually due to misuse or overuse of the voice rather than the testosterone itself. 

Low Testosterone and Voice 

Low testosterone levels can have various effects on the body, but their impact on the voice is generally more subtle, especially in adults.

Here’s how low testosterone might relate to voice changes: 

Post-Puberty Voice Changes

In adult males, the voice typically stabilizes after puberty, and the changes that testosterone causes in the vocal cords during this time are largely permanent. Therefore, a decrease in testosterone levels later in life usually does not significantly alter the pitch or depth of the voice that developed during puberty. 

Vocal Cord Muscle Mass

Testosterone plays a role in maintaining muscle mass, and this includes the muscles of the larynx (voice box), where the vocal cords are located. Low testosterone levels might potentially lead to a reduction in muscle mass, which could affect the strength or endurance of the voice. This might manifest as a voice that tires easily or lacks its previous robustness, rather than a change in pitch. 

Voice Quality and Health Conditions

While low testosterone levels in themselves might not drastically change the voice, they can be associated with other health conditions that might affect the voice. For example, conditions like hypothyroidism or certain autoimmune diseases can both affect testosterone levels and lead to voice changes. 

Psychological Effects

Testosterone has been linked to mood and energy levels. Low testosterone can lead to feelings of fatigue or depression, which might indirectly affect how a person uses their voice, potentially making it sound weaker or less energetic. 

Aging and Voice Changes

As men age, they naturally experience a decline in testosterone levels, a condition sometimes referred to as andropause or male menopause. This period is also associated with changes in the voice due to aging of the vocal cords and larynx, but these changes are more a factor of aging than directly due to low testosterone. 

Does Testosterone Affect Your Voice? 

The human voice is a remarkable instrument, influenced significantly by hormonal changes, particularly testosterone.

Let’s explore the anatomy of the voice box, the physiological process involved, and how testosterone plays a pivotal role in this transformation. 

The Voice Box (Larynx) and Vocal Cords Explained 

The larynx, commonly known as the voice box, is in the neck and houses the vocal cords. These cords are bands of muscle tissue that vibrate to produce sound when air is expelled from the lungs. The pitch and tone of your voice are determined by the length, thickness, and tension of these vocal cords.

During childhood, the larynx is relatively small, and the vocal cords are short and thin, contributing to the higher pitch of children’s voices. 

There are some evidence that testosterone can even lower your voice. Read more here; Does Testosterone Lower Your Voice?

Testosterone And Vocal Cords 

Testosterone plays a crucial role in the development of the larynx and vocal cords, especially during puberty. In males, a significant increase in testosterone levels causes the larynx to grow larger and the vocal cords to lengthen and thicken.

This physical change results in a deeper, more resonant voice, often referred to as the “voice dropping.” The process is less pronounced in females, as their increase in testosterone during puberty is lower. However, it still contributes to the maturation of the voice, though to a lesser extent than in males. 

Comparative Analysis of Pre- and Post-Testosterone Influence on the Voice 

Before the surge in testosterone during puberty, both males and females have similar laryngeal sizes and vocal cord dimensions, resulting in comparably pitched voices.

As testosterone levels rise in males, the disparity in voice pitch between genders becomes more pronounced. The post-puberty male voice is typically deeper and has a broader range of vocal tones compared to the pre-puberty voice.

In contrast, the female voice undergoes a more subtle change, retaining a higher pitch due to less dramatic hormonal influence. 

Testosterone Therapy and Voice 

This is particularly relevant when discussing testosterone therapy, a treatment that has significant implications for voice modulation. Let’s dive into what testosterone therapy entails, who it’s designed for, and how it can potentially alter one’s voice. 

Overview of Testosterone Therapy 

Testosterone therapy involves supplementing the body with testosterone to treat conditions caused by low levels of this hormone. It’s commonly prescribed for men with hypogonadism, a condition where the body doesn’t produce enough testosterone.

Symptoms of hypogonadism include reduced libido, fatigue, muscle weakness, and erectile dysfunction. Testosterone therapy aims to alleviate these symptoms by restoring testosterone to normal levels. 

In recent years, testosterone therapy has also become a key component of gender-affirming treatment for transgender men. By increasing testosterone levels, this therapy aids in the development of male secondary sexual characteristics, aligning physical appearance more closely with gender identity. 

Potential Voice Changes Due to Testosterone Therapy 

One of the most notable effects of testosterone therapy, especially in transgender men, is the deepening of the voice. Testosterone causes the vocal cords to thicken and lengthen, like the changes that occur during male puberty.

This results in a lower pitch and often a more traditionally masculine-sounding voice. However, the extent of voice change can vary widely among individuals. 

One article published in the Journal of Scientific Reports highlights that testosterone therapy is effective in altering certain speech parameters like pitch in transgender men but doesn’t fully achieve vocal tract masculinization. This underscores the significance of voice in gender transition and the necessity for supplementary strategies to fully realize vocal masculinity in transgender men. (2)

For cisgender men undergoing testosterone therapy for hypogonadism, the effect on the voice is usually less pronounced, as their vocal cords have typically already undergone testosterone-induced changes during their first puberty. 

Myths vs. Facts about Testosterone and Change of Voice

Let’s address some of these common myths and contrast them with scientific facts.

Myth 1: Testosterone Only Affects the Male Voice

Fact: While it’s true that testosterone plays a more significant role in deepening the male voice during puberty, it also influences the female voice, albeit to a lesser extent. Testosterone contributes to the overall health and function of the vocal cords in both genders.

Myth 2: Taking Testosterone Supplements Will Drastically Change Your Voice

Fact: Testosterone supplements or therapy can lead to changes in the voice, especially in transgender men. However, the extent of these changes varies widely among individuals. For cisgender men with normal testosterone levels, taking supplements is unlikely to cause dramatic changes in their voice.

Myth 3: Voice Changes Due to Testosterone Are Immediate

Fact: The impact of testosterone on the voice, particularly during puberty or hormone therapy, is a gradual process. It involves the thickening and lengthening of the vocal cords over time, not an overnight change.

Myth 4: High Testosterone Levels Lead to a Deeper Voice in Adulthood

Fact: Once an individual has gone through puberty, their voice has typically settled into its adult pitch. In adults, high testosterone levels do not significantly lower the voice further. The voice pitch in adulthood is more influenced by the size and shape of the larynx and vocal cords developed during puberty.

Myth 5: Testosterone Deficiency in Adults Will Raise the Voice Pitch

Fact: In adult men, a decrease in testosterone levels, often due to aging, does not typically result in a higher voice pitch. The changes that testosterone causes in the vocal cords during puberty are largely permanent.
