“Infertility? All concerned! “ For the 7e Infertility Awareness Week (from 1er on November 7), the main patient group in France, BAMP, has chosen to address the entire population. Virginie Rio, head of the association, which has been fighting for almost ten years to make the voice of infertile couples heard, feels that the subject has finally been taken seriously. The Pr Samir Hamamah, head of the reproductive biology department of the Montpellier University Hospital, has just been in charge of a “fertility plan”, with Salomé Berlioux, who testifies in Peach Skin (Stock, 288 pages, 20.90 euros) of the real Stations of the Cross that may represent a path of medically assisted procreation (AMP, or PMA for medically assisted procreation) in France.
