Testosterone Undecanoate Boosts Type II Muscle Fibers in American Males with Hypogonadism
Reading Time: 2 minutes Introduction Testosterone undecanoate, a long-acting injectable form of testosterone, has been widely used for the treatment of hypogonadism in men. Its impact on muscle mass and strength is well-documented, but the specific effects on muscle fiber type composition remain less explored. This study aims to elucidate the histological changes in muscle fiber types among American males treated with testosterone undecanoate, providing valuable insights into its therapeutic potential and mechanisms of action. Background and Rationale Muscle fibers are categorized into type I (slow-twitch) and type II (fast-twitch) fibers, each serving distinct roles in muscle function. Type I fibers are more efficient...
