Pre-treatment fertility preservation and post-treatment reproduction in long-term survivors of adolescent and young adult (AYA) cancer

Purpose: To describe recall of fertility-related consultations and cryopreservation and to examine reproductive goals and reproduction post-treatment in long-term survivors of adolescent and young adult (AYA) (age, 18–39 years) cancer. Methods: This study included n = 1457 male and n = 2112 female long-term survivors (M _age = 43–45 years; 5–22 years from diagnosis) who provided self-report. Clinical data were supplied by the Netherlands Cancer Registry. Results: Most male survivors (72.7%) recalled fertility-related consultations and 22.6% completed sperm cryopreservation. Younger age (OR = 2.8; 95%CI [2.2–3.6]), not having children (OR = 5.0; 95%CI [3.2–7.7]), testicular cancer or lymphoma/leukemia (OR = 2.8/2.5 relative to “others”), and more intense treatments (OR = 1.5; 95%CI [1.1–2.0]) were associated with higher cryopreservation rates. Time since diagnosis had no effect. Of men who cryopreserved, 12.1% utilized assisted reproductive technologies (ART). Most men (88.5%) felt their diagnosis did not affect their reproductive goals, but 7.6% wanted no (additional) children due to cancer. Half of female survivors (55.4%; n = 1171) recalled fertility-related consultations. Rates of cryopreservation were very low (3.6%), but increased after 2013 when oocyte cryopreservation became non-experimental. Of women who cryopreserved, 13.2% successfully utilized ART. Most women (74.8%) experienced no effects of cancer on reproductive goals, but 17.8% wanted no (additional) children due to cancer. Conclusions: Cryopreservation in men varied by patient/clinical factors and was very low in women, but data of more recently treated females are needed. Utilizing cryopreserved material through ART was rare, which questions its cost-effectiveness, but it may enhance survivors’ well-being. Implications for Cancer Survivors: The extent to which cryopreservation positively affects survivors’ well-being remains to be tested. Moreover, effects of cancer on reproductive goals require further attention, especially in women who refrain from having children due to cancer.
