Basically you can now determine the sex of your unborn child after only 6 weeks. They sell you this kit online, you return it to them and they send you back the results within 1 to 2 weeks depending on how much you have paid.
It's made by a UK firm with also labs in the US, but I have read in a news article that their products are forbidden in India and China where the sex of the baby is still such an important matter.
It will probably be available on the black market anyway...
To think that people can buy this product (thank god it's kinda expensive) to figure out the sex of the child in time to decide whether or not they can legally abort, this is scary to me.
