In vitro fertilization (IVF) is an assisted reproductive technology (ART) procedure involving retrieving an egg from the woman's ovary and allowing sperm to fertilize it in a lab setting. When male infertility is an issue, intracytoplasmic sperm injection is used to ensure fertilization. The mature oocyte is held by a pipette and the sperm is injected directly into it. The fertilized egg (zygote) divides to become a morula, then a blastocyst, and finally an embryo.
