Psychosocial research into cancer-related fertility has concentrated on fertility preservation or adult survivors' concerns. This study reports on its hitherto unreported impact over the time from diagnosis to survivorship. Thirty-eight men and women aged<30, diagnosed as teens, were recruited to an exploratory qualitative study. Analysis used the constant comparison method, considered conceptually within a lifespan approach. Four key experiences of managing fertility matters influenced, or were influenced by, the aftermath of cancer treatment: (1) prioritising 'normality' and marginalising fertility; (2) fertility concerns compromising 'normality'; (3) ongoing impairments/health concerns mediating fertility matters; (4) fertility concerns dominating the cancer legacy. Professional and social networks provided few opportunities to ask questions, receive information, process feelings or develop handling strategies. Beliefs about the extent of fertility damage did not necessarily relate to information received. For some, fertility matters affected identity, well-being and life planning as well as reproductive function. This was not restricted to particular ages, life stages, gender or time since treatment ended and was heightened by associated stigma and silence. Opportunities for dialogue should be offered regularly across health and social work disciplines given fertility's psychological and social as well as medical significance.
