The steady increase of age at first birth is a well-known phenomenon in Western Europe, but its continuation raises the question of infertility at the end of the
reproductive life. In this context, my research proposes to study the entry into parenthood at late ages (mid-30s and over). In particular, I seek to highlight the life
circumstances which may lead to the postponement of a first birth to older ages in the French socio-medical context. Mixing quantitative and qualitative methods, I
investigate the professional and partnership pathways of late mothers and fathers, and how the prerequisites to parenthood can be in conflict with the time pressure that
can be perceived.
