Sympathetic level for the prostate.

Sympathetic level for the prostate.

• A. T11-L2
• B. T10-11
• C. T9-11
• D. C2-Vagus

Answer: (A)

Sympathetic supply to the prostate comes from the thoracolumbar outflow, with preganglionic neurons located around the T10 to L2 spinal segments. These fibers travel via the lumbar splanchnic nerves to the pelvic plexuses (inferior hypogastric plexus) and then reach the prostate. That makes the level around T10–L2 the correct range for sympathetic innervation of pelvic organs, including the prostate. Among the options, the range that sits within this thoracolumbar territory is T11–L2, which explains why it is the best choice. The other options either point to higher levels not typically associated with pelvic sympathetic supply or point to parasympathetic systems (such as the vagus or the sacral parasympathetics) that do not innervate the prostate.
