The lack of studying both males and females in the laboratory has recently attracted the attention of the public and the NIH Although thyroid hormone induces a conversion from slow to fast fibers and increases contractile velocity, sex-specific hormones estrogen and testosterone are implicated in skeletal muscle growth, fiber size, and minimally in contractile function.
