Fertility preservation (FP) methods for boys and young men, such as cryopreservation of testicular tissue or sperm, offer hope but are currently underused among young male patients with cancer. Despite guidelines recommending early discussion of fertility implications, many newly diagnosed males do not receive FP counselling or referral to fertility services. Male cancer survivors face a higher likelihood of infertility than their peers, yet focused FP decision-making support is lacking. This study aims to address this gap by developing and evaluating the first dedicated patient decision aid (PtDA) for boys and young male patients with cancer aged 11\u201325 years old, to help them make informed FP decisions before receiving cancer treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>The current study follows a multistage process: developing the PtDA, alpha testing for acceptability with former patients, parents and healthcare professionals, and beta testing in clinical settings to ensure effective integration into routine care.
