RESUMEN
The use of donated gametes and embryos in assisted reproduction techniques (ART) makes it necessary to examine interests that involve relevant ethical and legal considerations, which include the autonomy and privacy rights of the intended parents, donors right to privacy and the right of the minors to know their genetic origin. This article presents arguments to consider policies of more openness to obtain information from donors in order to protect the childs best interest in knowing his/her genetic origins. It concludes with the situation in Mexico, where ART has been carried out with donated gametes since several years ago; however, due to the absence of regulations to control these procedures, each establishment imposes its own criteria for the operation of its programs.
