Development of sex differences in the rabbit masseter muscle is not restricted to a critical period.

Journal of applied physiology (Bethesda, Md. : 1985) - 1 Mar 2002

English Arthur W, Schwartz Gail

Abstract excerpt

The proportions of muscle fibers of different phenotype in the adult rabbit masseter differ greatly in different sexes. These sex differences are not apparent in young adults, but arise under the influence of testosterone in the males. We examined whether this switch occurred during a critical period of postnatal development. Testosterone was administered to young adults 1, 2, or 4 mo after castration, and also...
