Does Testosterone Make You Taller?

Testosterone is well-known for its role in male development, energy levels, and sexual function. However, it also plays an essential role in physical growth, including height. In this blog, we’ll explore testosterone’s impact on growth, how it affects height at different ages, and whether testosterone therapy or natural testosterone boosts can help you increase your height.

Testosterone’s Role in Growth

Testosterone is a key hormone in the body that contributes to the development of male physical characteristics such as muscle mass, deep voice, and facial hair. During puberty, testosterone is essential in triggering the growth spurt associated with adolescence.

It helps stimulate bone growth and promotes the maturation of long bones, which can increase your height. However, testosterone is not the only hormone involved in this process; growth hormone (GH) and estrogen also play a significant role in bone growth and development.

Testosterone acts on the growth plates of your bones, which are responsible for lengthening your bones during the growing years. This is why during puberty, when testosterone levels rise, many boys experience significant growth in both height and muscle mass. However, once these growth plates close after puberty, the body no longer increases in height.

At What Age Does Testosterone Affect Height?

Testosterone has a profound effect on height during the pubescent phase, typically roughly between the ages of 9 and 15. During this period, testosterone levels rise significantly, especially in males, leading to accelerated bone growth.

The bone growth plates remain open during this time, allowing the bones to grow longer. However, once these growth plates close—usually around the age of 15-17—height increase is no longer possible, even with increased testosterone levels.

After the growth plates close, testosterone can still influence other aspects of bone health, such as bone density and strength, but it will no longer trigger further growth in height.

Can You Get Taller with Testosterone Therapy?

If you are beyond your growth years and wondering if testosterone replacement therapy (TRT) can help you increase your height, the answer is likely “no.” Once your growth plates close, testosterone therapy will not make you taller.

However, suppose you’re still in your growth phase and have been diagnosed with low testosterone levels or constitutional delay of growth and puberty. In that case, testosterone therapy may help trigger growth and development and improve bone density.

For those past the growth phase, TRT can still be beneficial in addressing other aspects of health, such as muscle mass, energy levels, and libido, but it won’t affect your height.
