Since 2011, reproductive medicine society has seen welcomes the scientific breakthrough to create life in the laboratories of embryology and thus solve the problems of infertility. This assessment was reflected with the Nobel Prize in Medicine to Dr.. Edwards, by the birth of Louise Brown, the first person to be born through in vitro fertilization (IVF).
Despite that have developed great technical advances in Assisted Reproduction , research continues in the field of life and now "carrier couples may inherited diseases have healthy children". Today in the embryology laboratory you can select those embryos that do not suffer from the genetic alteration that would cause serious and degenerative diseases.
