PGD for Gender Selection also referred to as PGS or Preimplantation Gender Selection is a technique that enables couples with a particular inherited condition in their family to avoid passing it on to their children. It is also used with the purpose of gender selection for couples who have had more children of the same sex to want to have a family balance and choose the gender of the baby. Sex selection is legal in most of the world, yet it has limitations. Preimplantation genetic diagnosis (PGD) screening is allowed in most countries to determine a genetic condition that the embryo might inherit. Yet specifically PGS (Gender Selection) is not allowed with the specific purpose of determining the sex of the child - in countries including China, India, UK, Australia, Korea, Canada, Belgium, Spain, France, Germany, Hong Kong and Italy. However, it is allowed in select countries such as former soviet countries and in Latin American countries.

It means scientist using clone technology to breed a super-human, as it may be called. Humans have intervened in the natural selection of the species by using medical means to prolong life and to allow people to procreate when they could not have done so naturally. (This only affects the natural selection of the species when it affects whether or not a person can procreate, so medical intervention that prolongs life well after the age of being able to procreate is unlikely to have an effect on natural selection, unless it allows procreation with aged and therefore less healthy sperm or eggs.) This will eventually have an effect on the species by increasing the likelihood of heritable traits being passed on that are not to the benefit of the species. Evolution by human intervention would require that the intervention changes the set of people able to procreate. In vitro fertilisation would be one means by which this occurs if the difficulty with conceiving is a heritable one. The abortion of foetuses of the less desired sex, or bearing undesired traits or diseases is another.
