After a long-term followup of greater than 7 years organ sparing surgery represents a viable therapeutic approach to bilateral testicular germ cell tumor with an excellent postoperative outcome. Tumor enucleation might be considered a standard approach if the guidelines are respected, including cold ischemia, organ confined tumor less than 20 mm., multiple biopsies of the tumor bed, adjuvant local irradiation postoperatively to avoid local recurrence, close followup and high compliance.

Adjuvant chemotherapy with two courses of PEB is an effective and reasonable treatment option for patients with clinical stage I NSGCT who carry a high risk of relapse. No adverse late sequelae were detected within a median follow-up time of more than 6 years.
