A 32-year-old man undergoes vasectomy as a means of permanent bih control. A physician performing the vasectomy by making an incision on each side of the scrotum should remember which of the following statements most applicable to the scrotum?

The scrotum is innervated by branches of the Ilioinguinal, Genitofemoral, Pudendal, and Posterior Femoral Cutaneous nerves. The scrotum receives blood supply from the Posterior Scrotal branches of the Internal Pudendal Aeries and the Anterior Scrotal branches of the External Pudendal aeries, but it does not receive blood from the Testicular aery. It is drained by the Posterior Scrotal veins into the Internal pudendal vein. Superficial inguinal lymph nodesreceive lymph from the scrotum, penis, buttocks, and lower pa of the anal canal, and their efferent vessels enter primarily to the external iliac nodes and ultimately to the lumbar (aoic) nodes.* Whereas the lymph vessels from the testis drain into the upper lumbar nodes. The deep inguinal nodes receive lymph from the testis and upper pas of the vagina and anal canal, and their efferent vessels enter the external iliac nodes.
