The DNA of a body does not naturally change (in any organized way). Cells pass on changed DNA only to their progeny. Only genetic changes to gametes will be passed on genetically to children. However, the regulation of DNA can be transmitted. One can turn genes on and off throughout the body by exposing the cells to particular signals such as hormones. But those don't change the DNA, they just change the interpretation and usage of the DNA that's already present.
