Choosing the Future - The Science of IVF and Genetic Testing
Imagine a world where parents can peek into the genetic futures of their potential children, selecting embryos that are less likely to develop certain diseases. This isn't a scene from a sci-fi movie but a reality unfolding today, thanks to advancements in IVF (In Vitro Fertilization) and genetic testing. This topic is fascinating because it sits at the crossroads of technology, ethics, and personal choice. It raises crucial questions about the role of science in our lives and how we navigate the fine line between innovation and ethical considerations. For you, as a student, this is a chance to explore cutting-edge science that could shape the future of how humans reproduce, and to reflect on the implications such technologies have on society and personal morality.

Genetic testing
A type of medical test that identifies changes in chromosomes, genes, or proteins to predict the risk of diseases.

Polygenic score
A number derived from testing multiple genetic variations, predicting the likelihood of certain traits or diseases.

Embryo
An early stage of development for living beings, in humans, this is from fertilization until about eight weeks.

Eugenics
The practice or advocacy of improving the genetic quality of the human population, often associated with controversial or unethical policies.

Controversy
A prolonged public dispute, debate, or contention over a matter of opinion or concern.
