Genetic Background Influences Cortical Bone Response to Ovariectomy

Abstract

The magnitude, timing, and location of cortical bone loss after OVX varied significantly among A/J, B6, and C3H mice. The subsequent changes in mechanical properties after OVX depended on the variable bone patterns as well as the size and shape of the adult bone. Our results suggest that patterns of estrogen deficit-associated cortical bone loss are genetically determined.
