The Benefits of Human Genetic Engineering Essay

Pre-implantation genetic diagnosis is a revolutionary procedure that utilizes in vitro fertilization to implant a healthy egg cell into the mother’s uterus after it is screened for mutations or other abnormalities. That way, only healthy eggs can develop to term and become beautiful, bouncing boys or girls. Designer babies have a bright future in the face of science because they are genetically engineered to be: disease free; viable donors for a sibling or parent; and with optional elimination of any severe cosmetic disorders that might develop,—without risk to human diversity in the future. One of the most well-known, wide-spread, and enigmatic diseases on this Earth is cancer. It sneaks its way into family blood lines and travels …show more content…
If money were not in the equation, this might someday be a viable cure for cancers. If geneticists screened every embryo and removed the cancerous genes, they could potentially exterminate the disease! This would take years and not every child could be accounted for, but it would be a start.
Embryo Screening is a Godsend for couples who might have otherwise passed on an inherited disease like Huntington’s. Huntington’s disease is degenerative, destroying nerve cells in the brain and affecting the use of muscles and hindering cognitive thinking. The “onset of [Huntington’s Disease] symptoms… [can] occur anywhere from 40 to 70 years of age” (Norrgard). Most parents, at the time of onset, have already passed on the disease to their kids without knowing it. Pre-implantation could have prevented this from occurring. But what if the disease was a disability instead, like deafness or blindness? Most families turn to embryo screening as a way to ferret out harmful genes and eliminate disability but there is another side to PGD called “negative enhancement”. On this flip-side, “The technique [of PGD] also may… [be used] to select an embryo likely to have the same disease or disability, such as deafness, that affects the parents” (Naik). A child who shared the parents’ disability would grow up accustomed and suited to the lifestyle, whereas a child not born with that disability might not be as comfortable in a household tailored
