Nowadays, our life is surrounded by technology in many different ways to improve our quality of life or simply to make our lives easier. We can constantly find new advances and new techniques in science, one of these advances seems to be very controversial, this advance is genetic modification, and more specifically engineered babies. According to the Commonwealth Scientific and Industrial Research Organization (CSIRO) said genetic modification, also known as genetic manipulation and genetic engineering, is an organism that has been modified in some way using biotechnological techniques. The whole organism is made of cells, these cells have a nucleus that contains DNA (they contain information like a library) and our genes (instruction books for each of us) are made of DNA (CSIRO, 2011). Knowing this, we can present ourselves as designer babies, i.e. children whose genes have been modified by us selected to ensure that some particular gene is present or to prevent or eliminate a particular deficiency (Oxford Dictionaries, n.d.). This could give parents more control over their children's genes before they are born, and this will be possible through two assisted human reproduction procedures that will modify the genes of these future people, through preimplantation genetic disease (PGD) or in vitro fertilization (IVF). ) (Madriaga, A, Bates, N.) It should not be a problem for our society today to make this procedure more common, however it will have a profound impact on society. It seems that mostly we will get positive things from Designer Babies, such as eradicating diseases or health problems, or parents will be able to have children who look like us in a certain way, because there are some parents who may have physical preferences... . half of the card ......characteristics (height or temperament). In the near future it will also be possible to eliminate the disorder or disease not only from the child, it will be possible to eradicate this disorder or disease for future generations, in more scientific words germline engineering (improvement of reproductive cells)(Baird,S. , 2007) Germline engineering offers a large number of possibilities, from the elimination of diseases to increased intelligence, changes in human longevity, increased muscle mass and much more (Baird, S., 2007). Baird (2007) stated that gremline engineering has paved the way for the complete modification of the human race, which means that we may come to be improved in all aspects. In tailor-made children there is another important factor that we should consider, the fact that parents will be able to decide the sex of their children and what they will look like..
