The effect of an acoustic calling signal on the sex hormone level in the blood of white mice

The action was studied of synthesized acoustic signals, similar to the natural invocatory ones by their characteristics, on the level of sexual hormones in male and female mature laboratory mice, and also the dependence of these hormonal shifts on rhythmic organization of the artificial sound signals. As a result of the experiments it was convincingly shown that synthesized acoustic signal with the frequency of 3500 Hz (S-1) caused a functional load on the glands of internal secretion which was testified by statistically significant increase in the level of sexual hormones in the blood of males (by testosterone and extradiole) and female mice (by extradiole and progesterone). In order to clear up the role of rhythmic organization of signal studies were conducted with the application of synthetic acoustic signal (S-2), different from S-1. The analysis of the data revealed the absence of significant changes in the level of sexual hormones both in males and in females during S-2 sounding.
