With the widespread use of contraception (mostly female) in the second half of the 20th century in most Western countries and the substantial scientific advances in assisted reproduction, the concept of “family” is expanding and the dissociation between parenthood and conjugality is increasingly questioning. Here, we assess the significance of the dissociation/conciliation between conjugal life and parenthood through sociological interviews which were conducted with “voluntarily childless people.” “Voluntarily childless people” evidenced the contradictions between the normative conditions of the “work” of being parent and of the “work” of being partner in love and sex.
