[Surrogacy, uterus transplantation and artificial uterus: approaches from the biolaw]

More than forty years after the first baby's birth through in vitro fertilization, innovations in the field of human reproduction have experienced a significant growth increase. Those first techniques have led evolved to others that push the biological limits of reproduction. Recent developments in genomic editing -particularly, CRISPR/Cas9 technology- had leaded an intense ethical, social and legal discussion about the boundaries limits of the new models of human reproduction, and their consequences in recent years. The number of conflicting legal interests suggests that the application of these techniques must combine the respect for the law, the defense of the human rights of all the agents involved in the process, and the freedom of scientific research. The present paper tries to deal with the diverse ethical implications and legal limits of three of those techniques, recently developed or to be developed in the near future: surrogacy, uterus transplantation and artificial uterus.
