High risk of infertility and long term gonadal damage in males treated with high dose cyclophosphamide for sarcoma during childhood

Abstract

The results of the current study show a high risk of gonadal dysfunction in men exposed to cyclophosphamide during childhood as part of a VAC/Adria-VAC chemotherapy regimen. Exposure prior to puberty was not found to be protective, and the risk of infertility appeared to increase with higher doses of therapy. To the authors' knowledge the clinical significance of impaired Leydig cell function beginning at a young age is unknown and merits further study.
