For adolescents and young adults (AYAs) with cancer, fertility preservation is recommended before starting gonadotoxic treatments. This is an important aspect of psychological support in the treatment of the disease. However, the enormous psychological impact of this procedure on adolescents and young adults with cancer needs to be addressed by professionals. The traumatic nature of cancer diagnosis disrupts the psychosocial development of AYAs. A young adolescent’s perception of reproduction, and in particular of sperm freezing, is greatly altered by the disease. For a teenager, the success of sperm banking results from a positive balance between facilitators and barriers, which are mentioned here. Moreover, this video proposes a symbolic interpretation of sperm banking, referring to landmarks integrated during childhood, especially in fairytales. Furthermore, it offers an original video documentary that can be used as an information support to help AYAs adhere to the process of preserving their fertility through sperm freezing.
