Research on supernumerary embryos: the challenge of recon- ciling opposing interests and fast-evolving technologies

The paper addresses the issue of the legality and ethical admissi-bility of invasive experiments on embryos and the correlated one of the degree of legal protection and dignity to be recognized for human embryos, particularly in light of the growing importance that scientific research on embryonic stem cells has been gaining from the clinical and biomedical standpoints in the therapeutic treatments of diseases so far considered incurable, in the interest of public health. Furthermore, the issue of experimentation on cryopreserved supernumerary human embryos is still extremely polarizing, which makes it harder to arrive at shared solutions. The author hopes for a broad-ranging debate at the international level, for the ultimate purpose of achieving shared regulatory frameworks.
