Height is often considered a fixed trait, with genetics being the primary factor that determines how tall you grow. However, for many people, the idea of increasing their height or achieving their maximum growth potential remains an intriguing possibility. Among the various factors that influence growth, testosterone is one that is often discussed. As a hormone predominantly associated with male development, testosterone plays a key role in physical growth and development during adolescence. But can testosterone make you taller, especially after the typical growth period has ended?
In this article, we will delve into the relationship between testosterone and height, how testosterone affects growth, and whether it can influence your height as an adult. We will also address some common questions and provide clarity on this fascinating topic.

Understanding Testosterone and Growth
What is Testosterone?
Testosterone is a steroid hormone that is primarily produced in the testes in men and in smaller amounts in the ovaries and adrenal glands in women. It is responsible for a range of physical and physiological changes, especially during puberty. Testosterone plays a major role in the development of secondary sexual characteristics in men, such as the deepening of the voice, facial and body hair growth, muscle development, and bone density.
In addition to these roles, testosterone also influences bone growth and density, making it a crucial factor in determining how tall a person can grow, particularly during their teenage years.
How Testosterone Affects Growth and Height
Testosterone contributes to growth in a number of ways, but its impact on height is closely tied to its role in bone development. During puberty, testosterone helps stimulate the growth of bones and cartilage, particularly in the long bones of the arms and legs. As these bones grow longer, the person experiences an increase in height.
However, the relationship between testosterone and height is more complex than it might seem. Testosterone acts on the growth plates (also known as epiphyseal plates), which are located at the ends of long bones. These growth plates are responsible for bone lengthening during childhood and adolescence. When testosterone levels rise during puberty, they stimulate the growth plates to produce new bone tissue, leading to an increase in height.
The Role of Estrogen in Height Growth
While testosterone is essential for promoting growth in males, estrogen, the primary female sex hormone, plays a crucial role in both males and females. During puberty, estrogen helps to close the growth plates, signaling the end of vertical growth. This is why, after puberty, individuals generally stop growing taller, regardless of their hormone levels. For men, the conversion of testosterone into estrogen via the enzyme aromatase is critical because it contributes to the closure of the growth plates.
Can Testosterone Make You Taller After Puberty?
The most significant factor in determining whether testosterone can affect height is whether your growth plates are still open. For most individuals, the growth plates close during late adolescence, typically between the ages of 16 and 21. Once the growth plates have fused, it becomes impossible for a person to grow taller, regardless of their testosterone levels.
If testosterone is introduced after the growth plates have closed (for example, in the form of testosterone replacement therapy), it will not make you taller. In fact, it may actually speed up the closure of the growth plates, causing growth to stop earlier than it otherwise might have. This is why testosterone therapy is not used to increase height in adults.
Can Testosterone Increase Height Before Growth Plates Close?
For adolescents who have not yet gone through puberty, or for those with a delayed puberty (sometimes medically induced or caused by conditions like hypogonadism), introducing testosterone treatment can help stimulate growth and accelerate the onset of puberty. In such cases, testosterone may help increase height by promoting the development of bones and the elongation of long bones, provided the growth plates are still open.
However, once puberty is complete and growth plates close, testosterone will no longer have an effect on increasing height. In these cases, testosterone can only contribute to other aspects of male development, such as muscle mass, bone density, and secondary sexual characteristics.
How Testosterone Therapy Can Affect Height
1. In Adolescents with Low Testosterone Levels
In cases where a young person has low testosterone levels due to a medical condition like hypogonadism (a condition in which the body doesn’t produce enough testosterone), testosterone replacement therapy may be prescribed. This therapy can help to trigger or accelerate the growth spurt seen during puberty, allowing the individual to reach their genetic height potential.
In these cases, testosterone therapy can help the body catch up with its growth by stimulating bone growth and the elongation of the limbs, but only as long as the growth plates remain open.
2. In Adults: Testosterone and Height
For adults who have already completed puberty and whose growth plates have closed, testosterone therapy will not increase height. While testosterone can help increase muscle mass, strength, and bone density, it will not lead to any height increase. In fact, excessive testosterone therapy in adults who have already finished growing can pose risks, including premature closure of growth plates (if done in a younger person) or other health complications such as cardiovascular issues.
3. Effects of Testosterone on Bone Density and Strength
Although testosterone will not increase your height as an adult, it can have a significant impact on bone health. Testosterone helps to increase bone mineral density, which strengthens bones and makes them less prone to fractures. This is particularly beneficial as we age, and testosterone therapy is sometimes used in older men to help reduce the risk of osteoporosis and improve overall bone health.
Can Testosterone Supplements or Steroids Make You Taller?
While it may be tempting to think that testosterone supplements or anabolic steroids will boost your height, the reality is more complicated. Testosterone supplements or steroids may lead to increased muscle mass and strength, but they will not increase height once your growth plates have closed. In fact, using anabolic steroids irresponsibly or without medical supervision can lead to a range of serious side effects, including liver damage, cardiovascular problems, and hormonal imbalances.
For individuals who are still growing, testosterone supplementation (under the guidance of a healthcare provider) may help them reach their height potential, but only if they have open growth plates.
Frequently Asked Questions (FAQs)
1. Can testosterone make you taller after 18?
No, after the age of 18, most individuals have already gone through puberty and their growth plates have closed. Testosterone will not increase height once the growth plates are fused. However, it can help with other aspects of physical development, such as muscle mass and bone density.
2. Can testosterone increase height in women?
In women, testosterone is produced in smaller amounts than in men, but it still plays a role in bone health and muscle development. However, just like in men, once the growth plates have closed after puberty, testosterone will not make women taller. Testosterone therapy is not typically used to increase height in women.
3. Can testosterone cause growth in adults?
Testosterone will not make an adult taller once their growth plates have closed. However, it can help improve bone density and muscle mass. It is often used in hormone replacement therapy (HRT) to address symptoms of testosterone deficiency in men, particularly those with low levels due to aging or medical conditions.
4. How do I know if my growth plates are still open?
The most reliable way to determine whether your growth plates are still open is through an X-ray. A healthcare provider can take an X-ray of your bones, typically focusing on the wrist, to assess whether the growth plates have closed or remain open.
5. Can testosterone therapy help me grow taller during puberty?
Yes, testosterone therapy may help adolescents with delayed puberty or low testosterone levels reach their full height potential by stimulating the growth of bones and cartilage. However, it is most effective when started before the growth plates close.
6. Are there any risks to using testosterone to increase height?
For individuals whose growth plates have closed, using testosterone or anabolic steroids will not increase height and may come with risks such as hormonal imbalances, cardiovascular problems, and liver damage. It is crucial to use testosterone therapy under the supervision of a healthcare professional and avoid self-medication.
Conclusion
In summary, testosterone can influence height growth during adolescence, particularly if a person’s growth plates are still open. It plays a crucial role in stimulating bone growth and development during puberty. However, once puberty is complete and the growth plates close, testosterone will no longer have an effect on height. Testosterone therapy can be beneficial for individuals with low testosterone levels or delayed puberty, but it should not be seen as a solution for increasing height in fully grown adults.
If you are considering testosterone therapy for any reason, it’s important to consult with a healthcare provider to understand the potential benefits and risks, and to ensure that you’re using it safely and effectively.
