When BBC Mundo journalist Ana Maria Roura found out she couldn't get pregnant, she decided to turn the camera on herself and document her struggle to become a parent through in vitro fertilisation, or IVF. Her documentary, Infertile, is available in Spanish and in English. Plus, the science of super-centenarians, with BBC World Service journalist Fernando Duarte.

Presented by Faranak Amidi. Produced by Alice Gioia and Caroline Ferguson.
