Genetic Diagnosis Vs Amniocentesis Essay

445 Words2 Pages

After researching preimplantation genetic diagnosis and amniocentesis there are many differences and similarities amongst the two. Amniocentesis process is deals with the amniotic fluid, which is removed from the uterus in order for the treatment to take place. During the procedure of genetic amniocentesis a sample of the amniotic fluid is used to locate specific chromosomes or abnormalities. There are only specific abnormalities that can be located through amniocentesis. Amniocentesis is an alternative for PGD, it is a high risk process which sometimes leads to termination of pregnancy. Preimplantation genetic diagnosis is consider when one or both parents have a genetic abnormality and is at risk of transferring to their children. The process of preimplantation of genetic diagnosis removes a cell from an in virtro fertilization embryo for genetic testing. Affected embryos are not used for this process, only unaffected embryos are used to prevent the later termination or pregnancy.
If the embryo is found in defect, it doesn’t mean that the child will not display all the symptoms. When there is a genetic defect there is usually two recessive genes which means there’s no dominant gene that can takeover. Some genotypes can be heterozygous which is when there is a recessive and dominant gene. If …show more content…

PGD, can detect number of risk factors that are linked to genetic issues. One of the things I like about this procedure is that it can detect genetic defects at an early stage; before the embryo is transferred back to the uterus. I believe this gives the couple time to allow their doctor to choose an unaffected embryo before it is put back in the uterus. PGD requires a process where biopsy is used which later may lead to the embryo being damaged; causing it not to go to the next stage. Couples can choose this procedure but it can possibly lead to no genetic defect being

Medi-Cult Case Analysis Medi-Cult, a biotech company based in Denmark, has developed a new alternative to In Vitro Fertilization (IVF) called In Vitro Maturation (IVM). These methods are used to help infertile couples have children. IVM significantly reduces the time needed to mature an egg from 30 days to just 2 days. Importantly, it is a relatively hormone-free treatment thus sparing women a number of psychological and physical side effects. Because the side-effects tend to be much-lessened, women at risk from hormone-related condition such as polycystic ovaries are offered the option of safer fertility treatment.

The risk to pass the defective gene and have affected child from two carrier parents is 25% with each pregnancy while the chance for having a child who is a carrier like the parents is 50% with each pregnancy. The chance for a child to receive normal genes from both parents and be genetically normal for that particular trait is 25%. The risk is the same for males and

Bioethics essay- Why prenatal testing for severe birth defects shouldn’t be denied to parents There is a belief that physicians should not recommend pre-natal testing for severe birth defects, as this might encourage parents to consider abortion.

In this essay I will give an account of both the deontological and utilitarian approaches. However, I shall argue against this belief on the basis that : 1 ) Deontology ignores the effects not having an abortion has on the child and the parents 2 )

Regardless of the improvements that have been made there is still a risk of miscarriages as a result. This risk factors can be contributed to the invasiveness of the procedure as well as the time during the pregnancy at which it is performed. The later the genetic testing is performed, the more developed the unborn child is and the later the possible abortion would take place. The two most common forms of testing are ¨amniocentesis or chorionic villus sampling¨ (Rebouché and Rothenberg 989). Both of these tests ¨[require] extracting cells from the fetus in utero, either through the mother 's abdomen or vagina¨ (Rebouché and Rothenberg 989).

What I noticed when I watched the Seahawks two games against the Bengals, and the Panthers were that the opposing teams must have found a weakness in the Seahawks defense through film of their inability to cover good tight ends. Against the Bengals tight end Tyler Eifert had eight receptions 90 yards two touchdowns. Carolina Panthers tight end Greg Olsen had seven catches 131 yards one touchdown which was the game winning touchdown that beat the Seahawks couple weeks ago. What the Bengals, and Panthers seemed to do was throw at strong side safety Kam Chancellor who's not really known to for his coverage skills. These tight ends were able to run good crisp routes that put Chancellor in bad positions to be able to cover them.

However, many scientists say this is already possible in a much safer and less invasive way. It is far easier to genetically screen embryos for high-risk versions of genes following in vitro fertilization and prior to implantation in the mother. Not to mention, we already practice this as a society, for example, when smart rich people marry other smart rich people, they usually produce another generation of smart rich people; which is known as assortative mating. Another example is when a mother aborts a fetus that has a genetic defect, or when IVF

This is usually in the case of a multi-fetal pregnancy, to decrease health risks to a mother carrying more than one child. However, this is very rare as it occurs only in 1%-2% pregnancies. On the other hand, in the Eastern part of the world, especially in China and India, it is very common for couples to have an illegal selective abortion. This kind of selective abortion is removing a fetus because they may have birth defects/disabilities or the gender of the child is not preferred by the parent. Few people may agree with this, particularly citizens of China due to the one-child policy that restricts the number of children a couple can have.

In vitro fertilization is the process by which an egg is fertilized by sperm outside of the body and then the embryo or embryos are then transferred to the uterus. This process has been used since the 1970’s and doctors keep finding ways to improve it. People worldwide have a very divided opinions about the use of IVF. Some see it as an opportunity to have a family and being able to have kids at an age where they feel comfortable enough, instead of having kids at an early age because of the risks that they would have if they wait. Women also have a better chance of getting their preferred job position if they know that they do not have to decide between a healthy baby or their job.

Today, traditional surrogacy has been replaced by gestational surrogacy in which the birth mother has no genetic tie to the child: she is simply the bearer.

The prenatal diagnostics and prenatal screening being routine procedures should be considered as advantage of modern medicine. It helps to reveal wide spectrum of fetus abnormal conditions, but not only congenital defects and malformations. Early detection of many of them could help to perform surgical correction and necessary management as soon as possible in order to save newborns’ lives. On the other hand, this method is widely discussed and it has many opponents, and in some countries prenatal diagnostic procedures is not considered now as a screening method. Main ethical issues are terminations of pregnancies in case of malformations, which may be supposed as eugenical abortion, inform consent and problem of decision-making process.
