To read the full abstract: Stem Cell Res Ther. 2018 Nov 21; 9 (1):317Spermatogonial stem cell transplantation (SSCT) could become a fertility restoration tool for childhood cancer survivors. However, the colonization efficiency of transplanted spermatogonial stem cells (SSCs) in animal models is about 12%, and the effectiveness of this procedure needs to be improved before clinical imple...

Brief summary: This multicentre retrospective cohort study evaluated testicular structure in 101 boys aged <14 years with solid tumors, CNS tumors, leukemia/lymphoma, or non-malignant hematological disorders, who were admitted for a fertility preservation programme between 2002 and 2018.The aim of the study was to clarify a possible role of the disease itself on the risk of infertility, independently of cancer therapies. Clinical data, testicular vol...
