Sanctity of life is being violated , because any research or medical procedure done with the intention to genetically modify human embryos is bound to involve the use of human embryos, many of whom would be eventually discarded. Worsened by the fact that this is a very new procedure more likely to involve more trial and error. Even if these oocytes (egg cells) may have come from eggs donated by women for research, it does not change the fact that they represent potential human lives. o Example: in a 2012 study by researchers from Oregon Health and Science University (OHSU) and Boston University School of Medicine, seven volunteers (aged 21–32 years) underwent ovarian stimulation and a total of 106 mature metaphase II (MII) oocytes were retrieved (a mean of 15 oocytes per donor cycle). None of these egg cells were used to create a viable pregnancy. Even though the purpose of these experiments is good (since families with a high risk of having sick children could have healthy ones), the means used to achieve it, which involves the manipulation and even destruction of embryos is not. R3: It is also a process that yields little clinical success. Mitochondrial replacement therapy is too poorly understood in humans, making human embryo experimentation an attempt that is largely ineffective.

What accounts for this is the fact that the human genome has 6 billion pairs of DNA and mitochondria have about 16,000, making it very challenging to predict their interactions. o The Nadiya clinic in Ukraine which performs pronuclear transfer, one of the 3-parent techniques, has tried the procedure on 21 women. Fourteen attempts failed . o In a recent experiment by Doug Turnbull of the Wellcome Trust Centre for Mitochondrial Disease, 58% of embryos created had traces of faulty mitochondrial DNA because residues of fluid from the mother’s egg stick to the nucleus when it is extracted. The team also discovered that in some of the cells extracted from the three-parent embryos, levels of defective mitochondrial DNA increased as the cells multiplied . Seeing as the procedure is still a relatively new one and one that yields little guaranteed results , the resources (funding, facilities, volunteers’ well-being etc.) channelled into the endeavour to genetically modify human embryos may not be worth it. R4: The use of genetic modification is also not medically necessary. Pre-implantation genetic testing can already shed light on whether embryos test positive or negative for genetic mutations. It is possible to test the DNA of IVF embryos and pick healthy ones, a process that adds about $4,000 to the cost of a fertility procedure. A man with Huntington’s, for instance, could have his sperm used to fertilize a dozen of his partner’s eggs. Half those embryos would not have the Huntington’s gene, and those could be used to begin a pregnancy. o Pre-implantation Genetic Diagnosis (PGD) can be used to identify approximately 2,000 inherited single gene disorders and is 98% accurate in identifying affected and unaffected embryos.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
