(Reuters Health) - Many U.S. fertility clinics don't tell egg donors that embryos made from their eggs may end up being used in stem cell research, according to a new government survey.

That's despite widespread opposition to such research, which is considered morally offensive by a third of Americans, researchers write in the journal Fertility and Sterility.
