Are detected for male and female clusters with a various vascular reactivity. The similar allocation on clusters of metrics dD%, level of an estrogen, testosterone in group female is revealed. In group male other allocation of metrics on clusters is observed. Among male with low reactivity of arteries there are clusters with low and average level of testosterone. In clusters male with average and high level of a reactivity of arteries the high level of testosterone is observed most. For the selected clusters the steady combinations of vegetative metrics of a level of sexual hormones, catecholamins, metrics of an electrocardiogram are peculiar.

Usage of cluster analysis has allowed to reveal follow-up legitimacies which are making clear correlation between vegetative and behavioral metrics in a population at rats.
