Approximately 490,000 babies are born every day worldwide. About 11,000 babies are born each day in the United States alone, which means that at least eight babies are born every minute. Whether a pregnancy is planned for or not, the size, physical characteristics, and intellectual capabilities of a baby are predetermined by the chromosomes that combine in the mother during fertilization. The possibility and probability of a baby having any number of genetic diseases is also determined by genes and the embryo that is fertilized. In 1967, however, a study done by British scientists Robert Edwards and David Gardner paved the way for a life-altering scientific program now known as preimplantation genetic diagnosis, or PGD (Jha, 1).
Edwards originally became interested in and began researching about couples with infertility problems while attending the Karolinska Institute in Stockholm, in the 1950’s. Previously, studies had proven that it was possible for egg cells from rabbits to be fertilized outside of the body. It was shown that if sperm was mixed with the egg cells in an appropriate environment, then the embryos could develop successfully without the need for another living system. With this knowledge, Edwards took it upon himself to continue the research at the National Institute for Medical Research in London, where he eventually discovered that it was also possible for human eggs to be fertilized outside of the womb. The first human embryo to be fertilized successfully outside of the human body was documented in 1969, followed by the first “test-tube” baby, Louise Brown, being born in 1978. Just two years later, the world’s first in-vitro fertilization centre, known as the Bourne Hall Clinic, was founded by Edwards and Eng...

In recent years, great advancement has been made in medicine and technology. Advanced technologies in reproduction have allowed doctors and parents the ability to screen for genetic disorders (Suter, 2007). Through preimplantation genetic diagnosis, prospective parents undergoing in vitro fertilization (IVF) can now have their embryo tested for genetic defects and reduce the chance of the child being born with a genetic disorder (Suter, 2007). This type of technology can open the door and possibility to enhance desirable traits and characteristics in their child. Parents can possibly choose the sex, hair color and eyes or stature. This possibility of selecting desirable traits opens a new world of possible designer babies (Mahoney,
Most people agree, in general, that designer babies are taking over and it is it’s a good thing. A designer baby is a human embryo that parents set , to produce desirable traits. According to Opposing Viewpoints Online Collection , Fertility Institutes in Los Angeles offered to let parents select their children’s hair and eye color. Crazy to think you’d be able to build your own baby. The process of creating this designer baby would be embryos modified to predetermine intellect , physical prowess , and beauty. People may question designer babies but “if you think women have the right to control their bodies , then they should be able to make this choice” right? (Citation?) There is a lot of science into creating a designer baby.
PGD has proven effective in patients who are of advanced age, have had recurrent miscarriages or repeated IVF failure and are either carriers of chromosomal diseases or have genetic history of such. PGD is used with an IVF to identify chromosomal mutations and genetic defects in embryos, where a cell from IVF is removed for genetic testing before implanting it into the uterus. This can either be performed as polar body biopsy,

In Vitro Fertilization (IVF) is a complex series of procedures used to help those who want children but struggle with infertility. The process consists of extracting eggs from a woman and collecting a man’s sperm sample then manually combining them in a lab dish. Once the embryo(s) are created they are transferred to a woman’s uterus. IVF is commonly used in woman who cannot conceive on their own due to different reasonings. “These include but are not limited to blocked or damaged fallopian tubes, male factor infertility, woman with ovulation disorders, genetic disorders, woman who have had their fallopian tubes removed and unexplained infertility.” (American Pregnancy)
Prenatal genetic testing has become one of the largest and most influencial advances in clinical genetics today. "Of the over 4000 genetic traits which have been distinguished to date, more than 300 are identifiable via prenatal genetic testing" (Morris, 1993). Every year, thousands of couples are subjecting their lives to the results of prenatal tests. For some, the information may be a sigh of relief, for others a tear of terror. The psychological effects following a prenatal test can be devastating, leaving the woman with a decision which will affect the rest of her life.
Test tube babies have long been stigmatized by society as the unnatural results of scientific dabbling. The words `test tube baby' have been used by school children as an insult, and many adults have seen an artificial means of giving birth as something perhaps only necessary for a lesbian woman, or a luxury item only available to the elite few. The reality is that assisted reproductive technologies (ART) have been helping infertile couples have children since 1978.1 The methods of in vitro fertilization, it's variants, and the other ART procedures are ways for persons that would otherwise have no hope of conception to conceive and, in a rapidly growing percentage of cases, give birth to healthy babies. As the technology has developed, the quality and range of assistance has developed as well. At present, the means of assisted reproduction and the capabilities of these procedures has grown at a somewhat dizzying pace. However, thought to the repercussions of the applications of ART are being disregarded to some extent while the public's knowledge and the understanding of embryologists and geneticists surges forward. It is possible given consideration to things such as the morality of these techniques, the unexplored alternative uses of these procedures, and the potential impact they posses that further development is unnecessary and possibly dangerous.
The idea of in vitro fertilization originated in the works of British geneticist and Oxford professor JBS Haldane (Milner). Haldane imagined the practice of “ectogenesis”, or pregnancy hosted in an artificial womb, in his 1924 book Daedalus (Rosen). Haldane’s book was the inspiration for Brave New World.... ... middle of paper ...
Prenatal genetic screening in particular is a polarizing topic of discussion, more specifically, preimplantation genetic diagnosis (PGD). PGD is one of the two techniques commonly used to genetically screen embryos in vitro; it is usually done at the eight-cell stage of division. PGD is most often performed when there is the risk that one or both parents carry disease-causing mutations. It is extensively used by high-risk individuals trying to conceive babes who will be free of particular mutations. PGD can test for over 50 genetic conditions and even allows for sex selection if there are underlying gender-associated medical conditions. When the results are satisfactory, the selected embryo is implanted into the mother’s uterus. While a controversial technique, preimplantation genetic diagnosis is one example of some of the good genetic testing can do, more benefits will be furthe...

Children and babies today hold the future. They control what the world’s future will be like and even how their future offspring will be. Many believe that designer babies have the power to change the future and develop a new world filled with “perfect humans.” “With so little control over the situation, most expectant parents say they don’t care what their baby looks like, ‘as long as it’s healthy.’ But secretly, they often have a dream baby in mind” (Bliss, 2012, p. 5). Parents can all agree that if their child is in a healthy condition, they are happy and thankful; however, every parent is guilty of wanting a child a certain way. If a parent could alter a child to be completely healthy with no diseases or ailments, have the perfect features and have the perfect personality, any parent would go beyond any limit to fulfill this. Designer babies are believed to have the possibility to complete this; however, the assertio...
Many debilitating and severe unwanted diseases, genetic disorders and disabilities can be avoided through the creation of designer babies. A child's quality of life would be drastically increased if they evade Down Syndrome, deformities or heart disease for example. In a sense, it isn’t all that different to hearing aid, medication for an illness or chemotherapy for cancer, but on a larger scale and earlier in someone’s life, before it even really begins in fact. Some people would argue that changing genes is changing who people are, which they view as ‘wrong’, but genes aren’t exactly the only things that make up a person anyway. The way that they grow up and their surroundings also make people...
Sir Robert Edwards was an English physiologist who always took an interest in the study of genetics. He was the mastermind behind the medical reproductive procedure called In-vetro fertilization (Johnson). Because of Sir Edwards’s extraordinary contribution to the medical field, women with predisposed fertility problems are possibly able to have children. Without IVF millions of people wouldn’t be living on Earth today. Although Sir Edwards IVF procedure is considered controversial, it certainly had, and continues to have, a huge impact on our society. Sir Edwards’ first successfu...
