Mitochondrial diseases are a rare form of inheritable disease, which are transferred to child via mother's faulty mitochondria. Diseases are fatal and we still do not know the cure. Because of the illness, child loses weight; he can lose sight and hearing, motoric and mental abilities. Scientists have discovered a mitochondrial therapy procedure to prevent the inheritance of mitochondrial diseases and the treatment of infertility. This procedure is done with the help of three parents: mother, father and the egg donor. As a result, the child has a genetic code of three parents.
Mitochondrial therapy contains ethical dilemmas, such as destructions of the embryo. In addition, we do not know what impact therapy will have on 'her' children. For now, there are not many scientific discussions, although the ethical debate has been very heated since the method emerged.
