Introduction:

In the transplantation of organs virtually all the ethical problems of medicine converge, so it has been considered a bioethical micromodel.

Objective:

To assess the current controversies in donation and organ transplantation from a bioethical perspective.

Method:

An exhaustive bibliographic review was carried out in the different internet sites that allowed us to select and stratify the information for a better understanding.

Results:

Aspects related to brain death, informed consent, organ reception, fetal tissue transplantation and the positions of different religions in relation to this process are addressed.

Conclusions:

In all the procedures for obtaining, assigning organs for transplantation and in the selection of recipients there are bioethical dilemmas, so the ethical principles of beneficence, non-maleficence, justice and autonomy must be contemplated.
