The Process Of Pgd ( Preimplantation Genetic Diagnosis )

4. What is it called when an egg from the female is withdrawn and fertilized with sperm in a laboratory for 2 to 3 days with subsequent implantation into the uterus?

in a laboratory setting -- an egg with sperm outside of a woman's womb. Once the embryo develops, it is implanted in a woman's uterus.

What is over-reaching? The definition may be unclear in many retrospects, but the true definition is ‘certain areas in knowledge that humans should not “explore or cross”. Throughout history there has been over-reaching of all types; examples of past and present societal over-reaching has been; Amelia Earhart attempting to circle the globe in a plane consequently ending with her disappearance over the Bermuda Triangle, the new idea of Preimplantation Genetic Diagnosis allowing technology to identify genetic diseases in a child’s DNA or even changing the appearance of your baby to have a “designer baby”, Henry Worsley attempting to become the first person in history to cross the Antarctic continent alone, with no aid from outside sources,

I hypothesize that there will be a strong deviation between the genotype frequencies of the two lab sections combined and that of the US. This experiment consisted of 26 individuals, of varying ethnical backgrounds, ages, and genders, who amplified their own DNA through the use of PCR. Their DNA was examined for the presence [(+/+) or (+/-)] or absence [(-/-)] of the Alu insertion through the use of gel electrophoresis.

What is Preimplantation Genetic Diagnosis? It’s basically were two parents have a child with a severe disease, they then make a second child to use as spare parts for the first. Also, is Preimplantation Genetic Diagnosis even an ethical choice? I suggest regulations to ensure abuse of this method is kept to a minimum

One example of genetic screening currently used, is screening for the defective breast cancer (BRCA) alle les. In addition to the genetic screening process, an individual undergoes several counseling sessions. The step by step process of individual genetic screening starts with isolation of an individual's DNA. DNA may be isolated from tissue cells, blood cells, or urine of a child, adult or fetus. The segment of DNA which contains the gene of interest, is th en amplified through the use of PCR (Polymerase Chain Reaction) with primers specific to the segment of DNA. The amplified segment of DNA is then sequenced and analyzed for changes which cause the particular disease. If changes are present, the individu al has a greater likelihood of getting the disease.

Prenatal testing detects changes in a fetus’ genes or chromosomes before birth. This specific type of testing during pregnancy can help parents make decisions about a pregnancy, but cannot identify all possible disorders or birth defects. (Campbell, Reece, Mitchell). It is one of the most basic genetic tests. Another form of genetic testing done before birth is called preimplantation testing, or preimplantation genetic diagnosis (PGD). Its purpose is to detect genetic changes in embryos that were created outside of the body, such as in-vitro fertilization, where eggs are fertilized outside of the body. In this case, cells are taken from these embryos and tested for specific genetic changes that are indicative of a genetic disorder. Only

“Before the procedure, donors receive daily hormone injections for a week to ten days, which over-stimulates the ovaries to produce more than the usual single oocyte per menstrual cycle. The American Society for Reproductive Medicine estimates that egg donors spend fifty-six hors undergoing interviews, counseling, and medical procedures related to the process.” (Chapter Preface)

The case presents us with extreme ethical issues pertaining to the human life. Do we use PGD and support embryonic killing or do we discard PGD and allow the birth of a child that is certain to be burdened with medical crises throughout the course of their life? It is tempting to say “Thou shalt not kill” but then again after considering the benefits of PGD, one might not take such moral stance anymore. PGD decreases the chances of giving birth to a genetic diseased offspring. Without it, there is likely to be serious hardship inflicted not only on the parents of the child but also the society and the child as well. It drastically reduces the chances of a complicated pregnancy and other medical issues such as miscarriages. It helps a great deal in saving lives that depend on stem or bone marrow transplant. PGD also appeals to the emotional minds of parents who are carriers of this genetic disorder by consoling their fears of bringing an abnormal embryo to the world. As a deontologist, Kant proposes certain principles that must be taken into consideration when determining what is ethical and unethical alongside what is morally wrong and right. The decision making of right and wrong are grounded by justice, benefice, no maleficence, human dignity, integrity, autonomy and vulnerability. He also believed in good will being as a result of the act of duty and not inclination. Finally his overall justification is based on the moral law “Act only on those maxims (or rules of

There are a number of different techniques used to assist reproduction however the most common of which is In-vitro Fertilisation (IVF). It was originally developed to treat infertility caused by damaged or blocked fallopian tubes however, it has since become the starting point for screening embryos for genetic disorders in typically fertile couples. The IVF process requires the woman to undergo ovarian stimulation in which ‘fertility drugs’ are taken to stimulate the maturation of multiple eggs (6-10 eggs) as opposed to just one. Once the eggs have matured and ready for collection a needle is inserted through the vagina and with the assistance of ultrasound the eggs are delicately removed. The next stage is where fertilisation takes place. Within 6 hours the embryologists prepare the partner 's sperms and adds this to the eggs which are left for a further 14-18 hours to incubate. The following morning the eggs are examined for signs of fertilisation and the successful ones are cultured for another 3-5 days. Most laboratories transfer

The procedure starts at the embryology laboratory where the embryologist will collect the embryos from the petri dish using a catheter which is connected to a syringe. At the time of collection the embryologist should make sure that the embryos are kept close to each other inside the catheter. When the embryos are inside the catheter, a small amount of air is also absorbed to ensure that they will remain in the catheter. The embryologist will then transfer the catheter carrying the embryos to the doctor inside the surgery room. The doctor will insert the catheter inside the vagina using a guide which will help him to reach more easily the uterus. Once the catheter has reached the uterus, the doctor will liberate slowly the embryos. The catheter will be checked again to make sure that all the embryos have been transferred. If the catheter is clear it means that the procedure is over. Twelve days after the embryotransfer the woman should perform a pregnancy test which will determine if there is a pregnancy or

In the United States, an estimated 2.3 million couples are considered infertile [Wekesser, 1996]. This creates a large need for infertility specialists and clinics specializing in fertility treatments. With the quickly advancing field of rep roductive services and the quest for creating better, healthier babies, a new service called Preimplantation Genetic Diagnosis (PGD) is being offered in conjunction with In vitro fertilization.

A. Normally, a petri dish is used and the eggs and sperm are combined together in the laboratory and provided with the appropriate environment for fertilization.

The process of gender selection requires in vitro fertilization to occur. During in vitro fertilization first fertility drugs are taken by a woman to stimulate the ovaries to produce multiple eggs for fertilization rather than the typical one egg per ovulation cycle. Once the eggs are ripened the doctors will remove eggs. Egg removal is done by use of a thin needle through the vaginal wall to remove the egg from the follicle. Next the eggs are fertilized with sperm in a petri dish in a lab. After three to five days the embryos’ DNA is analyzed. The analysis of the chromosomes is called preimplantation genetic testing (ABC News, 2016).

The process of in vitro fertilization includes five stage procedures which begin with ovulation monitoring of a woman. Many screening tests are performed before starting the IVF cycle. The typical tests include the ultrasound of the ovaries and the uterus i.e. the process of IVF begins by keeping track of the woman's ovulatory process. Next step involves the retrieval of the egg i.e. removing ova (egg) from the body of a woman which is done by the transvaginal process. This can be done either under light medication or minor anesthesia. Then, once the eggs have been retrieved, sperms collected from a man are
