Hormone Replacement: Testosterone undecanoate, when prescribed, acts as a form of testosterone replacement therapy (TRT) for men with low testosterone levels. Improved Sexual Function: It can improve libido, erectile dysfunction, and other sexual problems related to low testosterone. Increased Muscle Mass and Strength: Testosterone is crucial for building and maintaining muscle mass, and TRT can help increase both. Bone Health: Testosterone helps maintain bone density, and TRT can help prevent or reduce bone loss. Reduced Risk of Cardiovascular Events: Some studies suggest that long-term testosterone treatment may reduce the risk of major adverse cardiovascular events in men with hypogonadism. Potential Prostate Health Benefits: While prostate cancer risk is a concern with TRT, studies suggest that testosterone undecanoate may not increase the risk of prostate cancer in men with hypogonadism.
