Preimplantation Genetic Diagnosis (PGD) is a technique used in IVF to analyze embryos and check for the presence of genetic diseases, allowing the selection of healthy embryos. The medicine baby is a child generated for the purpose of treating a sick sibling, being a relevant practice in the medical field because it enables the cure of certain pathologies through the donation of tissues such as blood and bone marrow. The importance of PGD is highlighted, as it allows diagnosing and selecting embryos without genetic diseases, although it is necessary to consider ethical limits to preserve the integrity and dignity of the future child. The objective of this study was to analyze the criteria used in the Preimplantation Genetic Diagnosis for the generation of a drug baby. An exploratory literature review was carried out in databases such as Pubmed, Virtual Health Library, Google Scholar and journals between the years 2012 and 2023, in addition, the film "A proof of love" was analyzed to complement the investigation. While PDG and the drug baby generation advance healthcare in revolutionary ways, it is important to address ethical and social issues comprehensively and sensitively by ensuring that scientific advances are used responsibly and for the benefit of all involved.
