In vitro fertilization. Image 3 of 4. Computer artwork of a dividing fertilized egg cell (centre) into which a sperm cell was injected during in vitro fertilization (IVF). The injected sperm cell fertilized the egg cell to form a zygote which has genetic material from the mother and father. The cell then divides several times to form a ball of cells in the first stage of embryonic development. It is then placed in the uterine wall,allowing pregnancy to proceed as normal. IVF treatment enables couples with any of a range of infertility problems to conceive a child. For a sequence showing the development of an embryo from IVF treatment,see images M802/237-240 | |
