The preganglionic sympathetic fibers emerge from the ventral roots of the spinal cord and travel ejaculation the paravertebral sympathetic chain to relay either directly through the splanchnic nerve, or through relaying first in the celiac superior mesenteric ganglia and then through the intermesenteric nerve, to the inferior mesenteric ganglia A secondary afferent route is through the hypogastric nerve, ejaculation runs through the paravertebral sympathetic chain to enter the spinal cord through the thoracolumbar dorsal roots Dopamine and serotonin: influences on male sexual behavior. Physiology of ejaculation. Xulane reviews When enough stimulation trips arousal over into orgasm, it also triggers a storm of activity in the three ejaculatory centers deep in the brain.
