The theme of the book was the sad reality of the crime of trafficking in human organs and tissues in Brazil. An extremely thought-provoking topic, but one that is difficult to access. The aim of this work was to investigate, through bioethics, which legal and criminal asset is protected in the prohibition of trafficking in human organs, as well as the relationship between art. 149-A of the Penal Code (trafficking in persons) and art. 15 of Law 9.434/97 (Transplant Law). It discussed the permitted and prohibited types of organ transplants in Brazil. In addition, arguments were presented about the possible decriminalisation of the conduct, as well as its impact on the Brazilian health system. The crime was analysed through the lens of bioethics and its principles, as well as the doctor's conduct and responsibility for committing or participating in the crime of trafficking and trading in human organs. I invite the reader to take a look at this interdisciplinary investigation and wish you all a good read.
