Genetic differences in the levator ani muscle weight between inbred and congenic mouse strains.
Significant differences in relative weight of the levator ani muscle (LAW) between inbred and congenic mouse strains, differing genetically only by the major histocompatibility H-2 complex were found. It is assumed that a genetic factor (Hom-1), identical or closely associated wi th the H-2 complex, is one of the genes which influence LAW. These experiments suggest that for assay methods for myotropic activity of androgens groups of animals may be used with a homogenous genotype.
