STUDY OF SEXUAL DIFFERENCES IN ANOGENITAL DISTANCES IN THE PROCEDURE OF LABORATE MICE

Abstract

The anogenital distance is the distance between the anus and the external genitals. It is a sexual dimorphism that positively correlates with the effects of androgens on the fetus in both rodents and humans. In accordance with this, the aim of this study was to determine the sex differences in the anogenital distance in the offspring of laboratory mice. The experiment was performed on the offspring of laboratory mice on day 90. The experimental animals developed under conditions of physiological pregnancy without any outside interference during their prenatal development. And they were kept under standard conditions with round the clock access to water and food. The objects of the study were the following values: body weight, anogenital distance, anogenital distance index of the offspring of laboratory mice. The results obtained indicate that the anogenital index does not depend on body weight, but with a high degree of probability depends on the sexual offspring of female and male laboratory mice.
