Fig 7. The biopsied embryo is now returned to the incubator for further culture. The blastomere will now be analysed in the FISH lab.
Fig 8. The FISH probes are available as a "ready-to-use" kit from Vysis, USA.
 Fig 9. FISH signals from a normal embryo. We know these are from a male ( XY) embryo as each has a orange signal
( orange dot) representing a single X chromosome, and a green signal, representing a single Y chromosome.
Once the results are known, which takes about 4-6 hours, only the normal embryos will be replaced into the mother's uterus.
