Effect of androgen receptor blockade on baroreflex sensitivity. Baroreflex curves relating decreases in heart rate (HR) to increments in mean arterial pressure (MAP) evoked by phenylephrine and baroreflex sensitivity (beats min^-1 mmHg^-1) in conscious unrestrained male rats treated with flutamide (Flu.: 5, 15, or 30 mg/kg) or vehicle (Veh.) 20–24 h earlier. Data are means ± SEM. Numbers in parentheses are number of observations. One-Way Analysis of Variance (ANOVA) followed by Fisher's Least Significant Difference post hoc analysis, ** P < 0.01 vs. vehicle.
