Ovarian venous plasma flow rate (upper panels) and rate of secretion of estradiol by the ovary (lower panels) after electrical stimulation of the SON and ONP. a Illustration showing the experimental procedures for collecting ovarian venous blood. b control condition (without stimulation). c SON stimulation. d ONP stimulation. Magnitudes of responses during and after stimulation are expressed as percentages of the prestimulus values (5 min before the stimulation). Each point and vertical bar represents the mean ± SEM. *p < 0.05; **p < 0.01; significantly different from the control response using two-way repeated ANOVA followed by Bonferroni post tests.
