title: Bilateral testicular germ cell tumors.
abstract: Patients with testicular tumors have an increased risk of a second tumor in the opposite testicle. The surgeon should ensure careful follow-up, possibly with testicular biopsies if the opposite testicle is maldescended or atrophied. In addition, the patient should examine the testicle carefully and regularly. Hormonal substitution is mandatory.
