Mean blood pressure levels in the prone position at rest significantly increased in the luteal phase compared with the follicular phase by 2.76 mm Hg (P<0.05).

Do different phases of the ovarian-menstrual cycle affect blood pressure levels and Mayer wave characteristics in healthy young women?
Mean and diastolic blood pressure, along with sympathetic tone, increase during the ovulatory and luteal phases of the menstrual cycle in healthy young women, correlating with changes in spontaneous baroreflex sensitivity.
Mean Difference: 2.76
valor p: p=<0.05
The goal of the research is to investigate the special effect of ovarian-menstrual cycle phases on the level of women's blood pressure and characteristics of Mayer waves. 77 women aged 18-19 were tested under condition close to the state of basal metabolism in follicular phase (I), ovulation (II) and luteal phase (III) of ovarian-menstrual cycle. In phases II and III, the increase of mean and diastolic blood pressure level, in comparison with phase I in the prone position at rest and with psycho-emotional loading, were observed. The distinctions between variation parameters of R-R interval duration, stroke volume and its synchronization in phases II and III, in comparison with phase I, were observed in the prone position at rest, during tilt-test and with psycho-emotional loading. The substantial level of relationship between the power of Mayer waves and mean and diastolic blood pressure, mainly in phase I under conditions of all types, is observed. The maximum peak amplitude of stroke volume spectrogram is associated with pressure levels in the range of 0.04-0.15 Hz (rho from -0.33 to -0.64). The obtained results indicate the possible participation of spontaneous baroreflex sensitivity characteristics in keeping blood pressure level in women.
Луценко et al. (Sun,) conducted a observational in Healthy (n=77). Ovulatory and luteal phases of the ovarian-menstrual cycle vs. Follicular phase was evaluated on Mean blood pressure (BPm) in the prone position at rest (MD 2.76 mm Hg, p=<0.05). Mean blood pressure levels in the prone position at rest significantly increased in the luteal phase compared with the follicular phase by 2.76 mm Hg (P<0.05).
