Essentially it is a means whereby chromosomal defects, which can cause a variety of diseases, can be detected at embryo stage. This is of particular value to couples who are at risk of passing on any of their genetic defects to their unborn child.

Before PGS, the only way to diagnose a defect was to perf...
