In vitro fertilisation. Doctor injecting a human spermatozoon (sperm) into an egg during in vitro fertilisation (IVF). She is viewing the cell through a microscope. The procedure can be seen magnified on the monitor at centre left. The egg cell,which is held in place by the tip of a pipette (far left),has been pierced by a microneedle in a procedure known as ICSI (intracytoplasmic sperm injection). IVF is a method of artificially fertilising an egg. It is carried out when a couple cannot conceive naturally. It is common for several fertilised eggs to be introduced into the uterus,as there is a high rate of early miscarriage | |
