Direct electrical stimulation of the superior ovarian nerve in rats causes an increase in neuronal activity in the ipsilateral ovarian plexus nerve

Abstract Ovarian blood flow and neuronal activity in the ovarian plexus nerve (OPN) were monitored before, during and after direct electrical stimulation of the central cut end of the ipsilateral superior ovarian nerve (SON). Blood flow did not change during the observation period. Stimulation of the SON increased the frequency of action potentials in the OPN, suggesting an ovarian reflex pathway mediated by the SON and the OPN.
