Brief summary

Chemotherapy and radiotherapy can lead to spermatogonial stem cell depletion in pre- and peripubertal boys, potentially resulting in infertility during adulthood A testicular biopsy is considered a safe procedure performed in children prior to gonadotoxic treatment as part of a fertility preservation strategy. At the time of the procedure, parental involvement is essential-both in their role as legal guardians and due to the limited cognitive capacity of young boys to fully comprehend fertility preservation counseling. Long-term follow-up is necessary to evaluate the impact on fertility outcomes, psychological well-being, and overall satisfaction. The aim of this survey is to assess the perceived impact of fertility preservation counseling and the physical and emotional effects of undergoing testicular biopsy in this population, with the goal of identifying opportunities to improve patient experience and clinical care for future patients.

MeasureTime frameDescription
The impact on quality of life of fertility preservation during childhood or adolescence.From the start of the program in may 2005 and the last patient enrolled in may 2020Assessment will be conducted by means of a confidential survey in \> 18 yo patients who have undergone in their childhood a fertility preservation. The number of patients who are eligible for the follow-up survey (n = 64) within the fertility preservation program of the CUSL is important compared to the overall number of boys who have participated in such a FP programme worldwide (n=1033) in 2023. Recipients' satisfaction level will be evaluated by both general and specific scores. The general satisfaction score is calculated by combining the responses to questions rating specifically recipients' satisfaction on specific items using a 5 elements Likert scale (Very Dissatisfied to Very Satisfied) and responses to closed questions which inquire participants' global satisfaction on specific subjects.
