The new reproductive genetic technologies (RGTs), by contrast, aim to enhance human life, to do better than nature or traditional medicine does. As John H. Evans writes in Contested Reproduction, RGTs aim to “allow parents to influence the genetic qualities of their offspring more precisely than through ‘normal’ fertilization by a sperm and an egg after sex.” The techniques include preimplantation genetic diagnosis of embryos, human genetic engineering, reproductive cloning, sperm sorting for sex selection, amniocentesis, and in vitro fertilization (IVF), among others.
