Which of the following lymph nodes receive lymphatic drainage from testes?

Testicular lymphatics drain into the retroperitoneal lymph nodes; the right primarily into the interaoocaval area, the left into the para-aoic area, both just below the renal vessels. Lymph nodes of the testis extend from T1 to L4 but are concentrated at the level of the renal hilum because of their common embryologic origin with the kidney.
