Indicators (markers) of microcirculation stability of the temporal regions of the head in young male and female subjects were studied. In 20 healthy volunteers aged 18-19 years (10 men and 10 women), synchronous measurements of the microcirculation of symmetrical temporal regions of the head were performed by laser Doppler flowmetry. Numerical values of stability markers (T1, T2, ζ) and parameters a1, a2, b1, b2 of the differential equation system describing oscillatory processes in the microcirculation system of the studied regions were obtained using the computational and experimental methodology developed by us earlier. It is shown that the right-left hemodynamic balance of microcirculation in men is maintained at the expense of the balance between the change in blood flow on the right and the initial value of blood flow on the left (coefficient b1) and in women, by the balance between the change in blood flow on the left and the initial value of blood flow on the right (coefficient a2). In women, the contribution of the right channel of the microcirculation to the right-left hemodynamic is significantly higher than in men. In general, the quantitative indicators (markers) of the stability of the microcirculation of the temporal regions of the head in women were higher than in men, which attests to higher stress resistance of the female organism in comparison with the male.
