Background: Preserving fertility in young women with cancer is crucial for comprehensive care. Based on GBD 2023 estimates, approximately 1000 women aged 15-39 are diagnosed with haematological malignancies annually in Italy. Guidelines recommend timely fertility preservation (FP) counselling for all at-risk patients, yet real-world access data remain limited. Methods: This multicentre, retrospective observational study analysed FP counselling for women aged 15-39 with haematological malignancies from 2015 to 2023. Counselling data were extracted from the Italian Assisted Reproductive Technology Registry (IARTR). This data collection system, known as PreFerIta, was developed within a project supported by the Italian Ministry of Health to collect data on Fertility Preservation (FP) treatments in oncology patients and/or those at risk of iatrogenic infertility, provided in seven specialised ART centres across Italy. The PreFerIta database includes data on both oocyte cryopreservation and ovarian tissue cryopreservation. Annual visits were related to the estimated regional incidence of new haematological malignancies (GBD 2023). Counselling-to-incidence ratios, absolute/relative gaps, and 95% confidence intervals (CIs) were calculated. Results: From 2015 to 2023, an estimated 4473 new haematological malignancies occurred in the catchment regions. Concurrently, 1200 FP counselling visits were recorded. While incidence modestly declined, counselling activity remained high. The counselling-to-incidence ratio increased from 17.33% in 2015 to 31.92% in 2018, stabilising between 26% and 31% thereafter (30.98% in 2023). The relative counselling gap decreased from 82.67% to 69.02%. These ratios represent lower-bound estimates of access to specialised oncofertility consultations. Conclusions: In this Italian network, approximately one in four to one in three incident haematological malignancies in young women were associated with specialised FP counselling. This reflects a substantial integration of oncofertility services into haematology care, highlighting opportunities to further strengthen referral pathways and achieve full guideline concordance.
