This episode of the Progress Educational Trust (PET) podcast features Professor Alan Handyside – a pioneer of preimplantation genetic testing – explaining how and why it became scientifically possible, and also legally permissible, to test the DNA of IVF embryos.

This discussion – which originally took place at the PET Annual Conference – is introduced by Sarah Norcross (Director of PET) and chaired by Dr Philip Ball (science writer and broadcaster).

PET is grateful to Jon Nicoll, who created the opening and closing music for its podcast.
