Testosterone is a hormone that plays a key role in maintaining bone health in men. As men age, their testosterone levels naturally decline, which can lead to decreased bone density and an increased risk of osteoporosis. Testosterone replacement therapy (TRT) can help by restoring hormone levels, which may improve bone density and reduce the risk of fractures. However, TRT is not suitable for everyone and should be considered only after consulting with a healthcare provider. Regular monitoring and follow-up are essential to manage potential side effects and ensure the therapy is working effectively.
