[Genetic endocrine and ethological mechanisms of differential reproduction. I. A comparative genetic analysis of the basal testosterone level in the blood plasma and the relative weight of the testicles and accessory sex glands in male laboratory mice].
Comparative genetic study of the basal plasma testosterone level, relative weights of testicles, seminal vesicles, and preputial glands in 13 strains of laboratory mice showed significant interstrain differences in all indices studied. Under the relative rest condition, a significant positive interstrain (genotypic) correlation was found between basal blood testosterone level and the weight of preputial glands and testicles. At the same time, no intrastrain (paratypic) correlations between hormonal and morphometric indices under study were found. An important positive and highly significant paratypic correlative dependence was seen between the relative weights of seminal vesicles and preputial glands.
