Mean arterial pressure (a), heart rate (b), cardiac sympathovagal balance represented by LF/HF ratio (c), and baroreflex sensitivity assessed by the index of bradycardic and tachycardic responses induced by increases and decreases in arterial pressure (d) in male rats (M), female in the non-ovulatory phase of the estrous cycle (FNOV), female in the ovulatory phase of the estrous cycle (FOV), and ovariectomized females (FO) (n = 7 animals/group). Data are presented as mean ± standard error of the mean. *p < 0.05. MAP, mean arterial pressure; LF/HF ratio, low-frequency/high-frequency ratio; BRS, baroreflex sensitivity
