During in vitro fertilization, doctors collect a mature egg from the ovary and combine it with healthy sperm in a laboratory. The fertilized egg begins dividing and develops into an embryo. A specialist carefully removes a few cells from the embryo and tests them for certain inherited genetic diseases or chromosome problems. An embryo with suitable results may then be placed inside the uterus, where it can attach to the uterine lining and continue developing into a pregnancy. you
