IVF embryo testing. Screen showing a cell being removed from an embryo for pre-implantation testing. The cell will be genetically screened for disorders or abnormalities. The embryo was created by in vitro fertilisation (IVF), where harvested eggs are fertilised by sperm cells in a laboratory. The fertilised eggs are grown to embryos, and then assessed. Healthy embryos are either transferred to a patient's womb or frozen for future use.
