The IVF - in vitro fertilization - also called test tube baby is having an issue with morality. It was said that the IVF produces many zygotes or embryos meaning the start of life. But the parents want only 1 or 2 at the most. What happens now to the rest of the embryos? If they are the start of life then throwing them away or killing them is like killing lives according to advocates of pro-life.
