Key result
Fluctuations in ovarian hormones along the menstrual cycle are associated with unchanged blood pressure and heart rate, despite significant variations in homeostatic regulatory mechanisms.

Do fluctuations in ovarian hormones along the menstrual cycle affect the neurohumoral and autonomic nervous systems regulating the cardiovascular system in healthy women?
Despite significant variations in neurohumoral and autonomic regulatory mechanisms during the menstrual cycle, blood pressure and heart rate remain stable in healthy women.
Hirshoren et al. (2002) conducted an observational in Healthy (n=8). Menstrual cycle phases vs. Different phases of the menstrual cycle was evaluated on Neurohumoral and autonomic nervous system parameters. Fluctuations in ovarian hormones along the menstrual cycle are associated with unchanged blood pressure and heart rate, despite significant variations in homeostatic regulatory mechanisms.
