In vitro fertilisation. Computer artwork showing the microscopic procedure of injecting the DNA of a sperm into a human egg,during the process of in vitro fertilisaton (IVF). At centre is the rounded egg. A micro-needle (at right) has penetrated the egg and is injecting the spiral DNA genetic material of a single sperm cell. At left,a flat- nosed pipette is used to hold the egg steady while the needle is inserted. This technique ensures penetration and fertilisation of the egg,without wasting millions of sperm. It is a specialized technique which has been used successfully at IVF centres around the world,for the treatment of certain infertility problems | |
