Recommendations for Gonadotoxicity Surveillance in Male Childhood, Adolescent, and Young Adult Cancer Survivors: A Report From the International Late Effects of Childhood Cancer Guideline Harmonization Group in Collaboration With the PanCareSurFup Consortium

This is a clinical practice guideline for male survivors of childhood, adolescent, and young adult (CAYA) cancers. The guideline specifically discusses treatments associated with increased risk of impaired spermatogenesis, testosterone deficiency, and physical sexual dysfunction. Surveillance strategies for these outcomes are examined, including which patients require surveillance, which surveillance modality should be used, frequency of surveillance, and what should be done when abnormalities are identified.
