BBC Mundo journalist Ana María Roura and her husband, Sebastien Jesús, share their personal journey of attempting to become parents. After receiving a diagnosis of infertility, the couple turns to in vitro fertilisation (IV), the most common technique in assisted reproduction. They recorded their treatments for more than 3 years and filmed a sort of diary that helps the audience understand the process from a scientific perspective and also delve into the psychological impact of the treatments. Like Ana María and Sebastien and other characters in this film, millions of people worldwide confront infertility, which the World Health Organisation has described as a 'global fertility crisis'. Despite its widespread impact, infertility remains a taboo subject in many societies.
