Dr. Paniyiotis Zavos has been pioneering controversial fertility experiments involving the cloning of human embryos and implanting them in a woman's womb. Zavos claims he cloned 14 and implanted 11 embryos, though none have made it to birth.
Scientists have in the past managed to clone embryos for the purposes of harvesting stem cells, however it is Zavos that has taken that "taboo" step of actually implanting them. Zavos believes he is close to having a child a parent can take home.
The entire process was captured by Discovery Channel and was aired Wednesday in the UK. President Obama as well as the Pope have outwardly denounced human cloning.
