Effects of prazosin (a) and yohimbine (b) on the superior ovarian nerve stimulation-induced responses of ovarian venous plasma flow rate (a), ovarian venous estradiol concentration in ovarian venous plasma (b), secretion rate of estradiol from the ovary (c). Data are expressed as mean ± SEM (a n = 6, b n = 4). *p < 0.05 compared with pre-stimulus control values using a Friedman test followed by Dunn’s multiple comparison test. Stimulation for 5 min (0–5 min) was applied as indicated by annotation of the upper portion of each gray bar
