Childhood cancer survivors have identified fertility preservation as a major concern. Sperm banking is an established fertility preservation option in pubertal males. We sought to describe current practices in Canadian pediatric oncology programs, and to identify perceived barriers to sperm banking for male adolescents.
A questionnaire was developed to (1) describe current sperm banking practices and facilities; (2) report on the utilization of sperm banking; and (3) identify barriers to sperm banking and possible solutions to improve current practices. A healthcare professional with an interest in fertility preservation within each institution was approached to participate in the study.
Fifteen of 16 institutions participated, 2 have fertility preservation teams. Only one has written guidelines or adolescent focused educational material. Over 2 years, 50/262 (19%) adolescents in 12 institutions successfully banked a specimen. In 11 of these, additional information was available: of 85/172 (49%) adolescents offered the option to bank, 38/85 (45%) subsequently attempted. Reported barriers to sperm banking included the pressure to start therapy and restricted banking hours. Formal education of healthcare providers in fertility preservation practices, provision of financial support for families, and an adolescent focused approach were identified as important initiatives to improve sperm banking.
There is a disparity in current sperm banking practices in Canada and at present, <25% of eligible male adolescents attempt to bank sperm. The development of a fertility preservation team, adolescent-specific guidelines, adolescent friendly sperm banking units, financial support, and improving knowledge translation among professionals and patients may improve the rates of banking.
儿童癌症幸存者已将生育力保存视为主要关注点。在青春期男性中,精子库是一种已确立的生育力保存选择。我们旨在描述加拿大儿科肿瘤学计划中的当前实践,并确定男性青少年精子库的障碍。
开发了一份问卷,以(1)描述当前的精子库实践和设施;(2)报告精子库的使用情况;(3)确定精子库的障碍和改善当前实践的可能解决方案。每个机构都有一位对生育力保存感兴趣的医疗保健专业人员参与研究。
16 个机构中有 15 个参与了研究,其中 2 个有生育力保存团队。只有一个有书面指南或针对青少年的教育材料。在 2 年的时间里,12 个机构中的 262 名青少年中有 50 名(19%)成功地储存了样本。在这 11 个机构中,提供了更多的信息:在 172 名被提供选项的青少年中,有 85 名(49%)随后尝试了。报告的精子库障碍包括开始治疗的压力和有限的储存时间。在生育力保存实践中对医疗保健提供者进行正式教育、为家庭提供经济支持以及采用以青少年为中心的方法,被认为是提高精子库的重要举措。
加拿大目前的精子库实践存在差异,目前,只有<25%的合格男性青少年尝试储存精子。生育力保存团队的发展、青少年特异性指南、青少年友好型精子库、经济支持以及提高专业人员和患者之间的知识转化可能会提高储存率。
