IVF and Preimplantation Genetic Diagnosis Essay - 1048 Words

In America alone there are 6.1 million couples coping with infertility (ASRM). In vitro fertilization (IVF) is one of the many assisted reproductive technologies used to help infertile couples achieve pregnancy. Since IVF is costly (the average cost is $12, 400. for one cycle), time consuming and a very emotional situation, many couples have a limited amount of opportunities to commit to the procedure and every step should be taken to maximize the chances of a successful healthy pregnancy. Preimplantation genetic diagnosis, or PGD, is a valuable tool for infertility treatment technology and can facilitate in successful IVF cycles. The IVF procedure involves removal of eggs from the females ovaries using an ultrasound guided needle†¦show more content†¦The procedure merely delays continued cell division for a few hours, after which the embryo reaches the same number of cells as before and continues its normal development (Fischer). Figure A. Implantation failure and miscarriage are the two most common reasons for an unsuccessful IVF cycle. Implantation failure is defined as three or more failed IVF attempts. PGD is being used to improve implantation and decrease the number of miscarriage by testing for a specific chromosomal condition called aneuploidy. Aneuploidy is a situation in which either the egg or sperm has an extra (trisomy) or missing (monosomy) chromosome and is the cause of fifty percent or more pregnancy losses. An embryo with a monosomy will cease to grow before implantation. Only a few carrying a trisomy chromosome would develop to term. Those that are carried to term result in physical and mental defects such as Downs syndrome, Klinefelter Syndrome, trisomy thirteen and trisomy eighteen. By using PGD to transfer only chromosomally normal embryos, the number of pregnancies going to term will increase and births resulting in defects will minimize (Cohen). The accuracy of the PGD for aneuploidy is a bout ninety percent; however it does not increase the chances of successful IVF procedure. PGD is also highly encouraged for women seeking to get pregnant after the age of thirty-five with or without fertility issues.

Its main use is to test for heritable genetic disorders and chromosomal abnormalities, and it may be used to find embryos that are a tissue match for siblings who are living with certain genetic conditions. To undergo PGD, an embryo is created via in vitro fertilisation (IVF), the process by which fusion of an eggRead MoreGenetic Diagnosis ( Pgd )1368 Words   |  6 PagesCouples who have a known family genetic disorder understandably consider undertaking the PGD process. They look at PGD as an option to ensure that they produce a healthy offspring or to ensure a better chance of producing a healthy offspring. This is the main reason why there is the need for PGD. People who have tried In-vitro fertilisation (IVF) and failed are also likely to try/demand PGD. Other possibe candidates for PGD are people with chromosomal disorders, women age 35 and over and women expericn ingRead MoreShould Scientists Be Allowed to Perform DNA Tests on Selecting Human Embryos?1206 Words   |  5 Pagesvitro fertilization (IVF) is the process of forming a human embryo outside the womb. The process involves extracting several eggs from a woman’s body and then fertilizing them in a laboratory. A couple days after fertilization, genetic tests can be applied on a cell that is removed from the embryo. The DNA testing process is called preimplantation genetic diagnosis (PGD) and usually triggers the diagnosis of the embryos with genetic abnormalities but can also identify other genetic traits of the futureRead MoreQuestions On Genetic Diagnosis ( Pgd )1063 Words   |  5 Pagesâ€Å"Socioscientific Issues (SSI) are controversial social issues which relate to science.

This is done through the processes of in vitro fertilization (IVF) and preimplantation genetic diagnosis (PGD). This involves removing mature egg cells from a woman and fertilizing it with male sperm outside of the body. The embryos are then analyzed for abnormalities and mutations in the deoxyribonucleic acid (DNA).

What is In-Vitro Fertilisation and Preimplantation Genetic Diagnosis? 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 stimulationRead MoreWomen And Sexual Reproductive Organs1330 Words   |  6 Pagesbiological technology has led to a new, modern kind of conception: in vitro fertilization. In vitro fertilization (IVF) is defined as the â€Å"joining of a woman’s egg and a man’s sperm in a laboratory dish† (In Vitro Fertilization). You may wonder why a woman would consider in vitro fertilization instead of more natural, unassisted conception method. Both men and women in relationships consider IVF as an alternative to help a woman become pregnant when she cannot naturally.

None of these methods were based on scientific evidence. However, in recent years gender selection has been made possible through advances such as preimplantation genetic diagnosis using biopsy methods combined with in vitro fertilization and sperm separation using flow cytometry techniques (Reubinoff, 1996, p. 344). These methods can increase the likelihood of producing a child of the desired sex, although noneRead MoreEssay On IVF Treatment1484 Words   |  6 Pages IVF treatment must occur before PGD. Embryo development occurs on day 3 when a small hole is made in the soft shell of the embryo (Zona Pellucida) using a laser. On day 5, one or more cells are removed from each embryo (embryo biopsy). The embryos are then frozen and cells are sent to a PGD laboratory for analysis. The cells are tested from each embryo which informs them which embryos are normal. Normal embryos are thawed and transferred to the woman later.

Advances in Assisted Reproductive Technology have contributed to various innovations such as Preimplantation Genetic Diagnosis, which enables parents to choose prenatally the sex of their offspring (Bumgarner, 2007, p.1289). This technology enables parents to select the sex of their babies through the use of medical techniques. While it is considered as a major breakthrough in reproductive health, Preimplantation Genetic Diagnosis has been surrounded with bioethical
