Ethical questions about mitochondrial replacement in humans. Three-parent baby technique

We thus consider it necessary to establish a moratorium on their use in humans, at least until more is known about these aspects. If this knowledge is obtained, ethical questions would still remain to be resolved, among which we consider the most relevant to be those related to...

Transhumanism: the abolition of man?

Transhumanist goal intends to free human beings from their human condition with technological support What is transhumanism? What is the meaning of this concept? When we hear the word transhumanism, the idea may come to mind that it is possible to improve human nature, to go...

Genetic engineering of human embryos to treat diseases. An unprejudiced reflection

In the last five years, many laboratories worldwide have employed the genetic engineering technique known as CRISPR/Cas9, in the hope that it might one day be used to treat human diseases. Things seem to have accelerated in the last few days though, after the authorisation in the...

New advances and challenges in the production of human-animal chimeras

They had overcome the obstacle of using human embryonic stem cells, but that even so, a ethical difficulty remained with the producing organs formed almost entirely of human cells in experimental animals. It seems a little excessive that, in less than two months, we have...

Is the human embryo a living being of our species?

Few doubts that determining whether the preimplantation human embryo is a living being of our species is one of, if not the most, fundamental issues in modern bioethics. Another thing is whether that living biological being is, or is not, a human person. That, however, is another...

Gender identity disorders. Current scientific evidence

Introduction Management of so-called “gender incongruence, cross-gender behaviour, non-normative gender behaviour, gender dysphoria or transgender or transsexual behaviours”, hereinafter encompassed within the term “Desire for Sex Change” (DSC) is a...

Human infertility. Microsurgery for the treatment of tubal obstruction. Ethical and medical aspects

‘Reconstructive microsurgery could be important in the treatment of infertility’ One topic discussed in relation to the treatment of human infertility is the efficacy of tubal microsurgery for the treatment of Fallopian tube obstruction and its efficacy compared to in...

Ethical debates sparked by recent biomedical breakthroughs

 The urgent need to incorporate ethics into biomedical research Many of the problems presented by science during the course of its normal development raise bioethical concerns that must be considered. In this respect, the John J. Reilly Center for Science, Technology and Values...

Gene editing today. All we have to know about it and our bioethical assessment

Few scientific breakthroughs have been as important as the discovery of the CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats) technique as a gene editing tool. CRISPR/Cas9 is a natural system that provides bacteria with an adaptive response against viruses...

Human cryopreservation. Technique and ethical and moral assessment

There may be an insurmountable difficulty in relation to the revival of the cryopreserved cadaver Cryopreservation consists of preserving human individuals or organs at very low temperatures (less than -130°) in order to preserve them. The low temperatures decrease the metabolism...
