Where do lymphatics from the testes primarily drain?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Para-aortic lumbar nodes

Testicular lymphatics follow the gonadal vessels to para-aortic lumbar nodes because the testes develop high on the posterior abdominal wall, unlike scrotal skin which drains mainly to superficial inguinal nodes.

Option by option

  • A. Axillary nodes

    Axillary nodes receive lymph from upper limb and much of breast.

  • B. Para-aortic lumbar nodes (correct)

    Correct: testes drain to para-aortic lumbar lymph nodes.

  • C. Superficial inguinal nodes

    Superficial inguinal nodes drain scrotal skin, not the testes themselves.

  • D. Submental nodes

    Submental nodes drain parts of lower lip and floor of mouth.
