At a March 24 press conference (video), the president of the Pontifical Academy for Life announced the publication of a document on organ transplants from animals.

The document, entitled “Prospects for Xenotransplantation,” is dated November 2025. The document is an update of a 2001 document of the same title.

The theological and moral point of view sees no substantial problem in the utilization of different animal species (nonhuman primates or nonprimates), but leaves open the question of differing levels of sensibilities between animals of different species and that of equilibrium among species and within a species. The point should also be made that Catholic theology does not have preclusions, on a religious or ritual basis, in using any animal as a source of organs or tissues for transplantation to man.

 

The Pontifical Academy for Life announced a new document titled “Prospects for Xenotransplantation,” updating its 2001 guidance, which affirms that Catholic theology poses no inherent moral or religious objections to using animal organs, tissues, or cells—including those from non-human primates—for human transplantation, while acknowledging ongoing ethical considerations regarding the varying sensitivities of different species and the balance within animal populations.
