Testosterone plays a significant role in promoting bone growth, which is crucial in children experiencing growth delays. This hormone affects the growth plates in long bones, known as epiphyseal plates, by increasing both the rate of bone formation and mineralization. In children, testosterone contributes to the acquisition of peak bone mass, which is vital for long-term skeletal health and stability.

By stimulating the growth plates, testosterone supports the process of ossification, leading to increased bone density and overall skeletal development. This anabolic effect on the bones is particularly important during puberty when the growth plates begin to close; adequate testosterone levels can help maximize height potential before this closure occurs. Thus, its influence on bone growth is directly related to addressing growth delays in children.

Other options, while they may seem relevant, do not directly align with the primary effects of testosterone in the context of growth delays. For instance, while testosterone can influence muscle development and overall body composition, its primary function in addressing growth delays focuses on promoting optimal bone growth and health.
