Test tube babies

Genetic testing is becoming more popular, more accurate and less expensive which means more and more people will use this new technology not only for themselves but for in the womb testing. These markers called SNP's (single nucleotide polymorphisms) are used to predict certain diseases. Prenatal testing is used to detect changes in a fetus's genes or chromosomes before birth. This type of testing is offered during pregnancy if there is an increased risk that the baby will have a genetic or chromosomal disorder. In some cases, prenatal testing can lessen a couple's uncertainty or help them make decisions about a pregnancy. As more tests are developed and the confidence in their accuracy increases more and more parents, looking for the perfect baby, will chose to abort and try again. In time such testing will be done on lab created embryos and the decision to go ahead will be made by keeping or destroying and embryo. Eventually test tube babies will become the norm.
