Sperm aneuploidy after testicular cancer treatment: data from a prospective multicenter study performed within the French Centre d'Étude et de Conservation des Oeufs et du Sperme network

Genetic counseling of TC patients should include information on the potential elevated risk of aneuploid conceptus from sperm recovered after treatment and the necessity to postpone conception up to ≥12 months after radiotherapy and ≥24 months after more than two BEP chemotherapy cycles. However, few men receiving one or two BEP cycles and some dropouts are the main limitations of this study.
