Reduced vagal tone in women with endometriosis and auricular vagus nerve stimulation as a potential therapeutic approach
Abstract Sensory and sympathetic nerves have been shown to promote the progression of endometriosis through the release of neuromediators and the lesional activation of respective receptors. The role of vagus nerves (VN) in lesional progression, however, is completely unclear, despite the signs sugg...

Abstract Sensory and sympathetic nerves have been shown to promote the progression of endometriosis through the release of neuromediators and the lesional activation of respective receptors.
