BIG IDEA: In this speech I'd like to show how issues of disease prevention meet ethical concerns of customized conception.
Transition: First, let's explore some background.
I. What exactly is Pre-Implantation Genetic Diagnosis & how did it begin? A.Pre-Implantation Genetic Diagnosis (or PGD) is a procedure used with in-vitro fertilization and screens embryos for genetic disorders. 1.In PGD, a single cell from a 3-day old embryo is removed, fertilized in vitro, and then analyzed for genetic abnormalities. 2.Only the embryos that are free from the specified genetic mutation are implanted into the woman's uterus for conception. B.The concept of PGD is a relatively new phenomenon.
1. U.K. Scientists founded it in the late 1980's.
2. The first child to be born from PGD and in-vitro was in America in 1989.
Transition: Pre-Implantation Genetic Diagnosis can examine embryos for many genetic disorders. Next we'll take a look at some of the disorders that can be prevented as well as some positive effects from using genetic testing.
II.One side of the controversy claims that: Pre-Implantation Genetic...
