Our reproductive capabilities are changing in exciting ways, altering our fundamental understanding of fertility, reproduction, and even parenthood.

In this episode, we asked our guests what the consequences of novel reproductive technologies are likely to be, and how they will impact the future of human reproduction. Alice Reid told us about how reproduction has changed over the last 200 years and the likely demographic impact of assisted reproduction, while Lucy Van de Wiel introduced the important ways in which reproductive technologies must be considered in the context of wide social and political issues. Thorsten Boroviak shared his exciting and cutting-edge research on developing new reproductive technologies. We cover topics ranging from egg-freezing, so-called ‘three-parent-babies, and the importance of studying the embryonic development of primates.

This episode was produced by Nick Saffell, James Dolan and Naomi Clements-Brod. Annie Thwaite and Charlotte Zemmel provide crucial research and production support for Series 2.
