This has resulted in an increased focus on male survivorship programmes, including fertility preservation. Whilst the gonadotoxic effects of cancer therapy are widely recognised, there is a paucity of data regarding trends in sperm cryopreservation. In particular, there remains a lack of knowledge regarding the types of cancers for which preservation is undertaken and whether there has been an increase in the utility of services. METHODS: An analysis of all oncological sperm cryopreservation at a UK tertiary centre between 1992-2016. Primary measures concerned trends in referrals over this period; in particular, the number of patients, the malignant indication for cryopreservation and patient age. Pre-freeze semen parameters were also assessed over time and used to calculate Total Motile Count (TMC). RESULTS: 3433 oncological patients cryopreserved sperm during the 25-year period. Referrals increased from each year group to the next, with an overall rise of 112%; from 415 (1992-1996) to 878 (2012-2016). Testicular malignancies remained the most prevalent indication for sperm cryopreservation throughout, although the relative contribution of each cancer type changed over time (p<0.001). Most notable was the rise in the proportion of patients with prostate cancer, from 0.5% of patients (1992-1996) to 5.6% (2012-2016). The median age of patients freezing sperm increased over the study period (p<0.001), from 29 years (1992-1996) to 32 years (2012-2016). Overall, 5.5% of men (n=190) were aged 50 or over at the time of their cryopreservation; with 39% of these individuals (n=74) banking sperm between 2012-2016. In all, 339 teenage cancer patients (aged 13-19) cryopreserved. Whilst there was an absolute increase in the number of teenage patients seen over the 25 years, the proportion they accounted for in each year group slightly reduced; from 9.2% (1992-1996) to 8.9% (2012-2016). Median TMC values did not change significantly across the timeframe, either overall or for individual cancer types. CONCLUSIONS: This study represents the largest single-centre evaluation of oncological sperm cryopreservation. We report a number of important trends over a 25-year period; the number of patients electing to bank sperm before oncological therapy is increasing, whilst the types of cancer encountered are changing. Furthermore, there has been a rise in the number of patients cryopreserving sperm at both extremes of age. These findings are encouraging and indicate an increased awareness of fertility preservation amongst men of all ages and cancer types.
