IVF embryo. Light micrograph of an embryo created by in vitro fertilisation (IVF). This embryo will be implanted in the patient's uterus. Several embryos are usually implanted to give the greatest chance of a successful pregnancy. However, this can result in multiple births. IVF allows infertile couples to conceive a child.
