4) The man provides semen, the sperm are processed, use only healthiest ones 5) The eggs are extracted from the follicles 6) Each egg is mixed with sperm and kept overnight in an incubator 7) The dishes are checked to see if fertilization has worked 8) Two or three embryos are selected and placed into the uterus

9) A pregnancy test is taken to see if any embryos have implanted 10) A scan is done to check if pregnancy is continuing normally
