Because scrotal approach for biopsies could disseminate testicular tumors, Chevassu suggested inguinal exploration and occlusion of the testicular vessels before biopsy of suspicious lesions.
I use a pun to remember this - "Chew vessels" to prevent seeding: Chevassou.
Other facts you must remember are - Seminomas are radiosensitive. They respond to chemotherapy with cisplatin as well.
And that teratomas have frequent lymph node involvement.
That's all!
