RELATIONSHIP BETWEEN INTERHEMISPHERIC ASY MMETRY AND MORPHOFUNCTIONALASYMMETRIES OF FEMALE REPRODUCTIVE-SYSTEM IN COMPARATIVE-EVOLUTIONARYASPECTS

In experiments carried out in female rats it has been established that there is a connection between morphological asymmetry of uterine horn s and adnexa and orientation of encephalic interhemispheric asymmetry (EIHA). Unilateral adnexectomy and ablation of one of the uterine horn s resulted. in modifications of EIHA, which increased during pregnancy in the remaining horn. Comparative analysis of experimental results a nd the data obtained during examination of pregnant women (such as int erconnections of the placentation side with gestational dominant and i nitial orientation of the lateral phenotype) suggests an important rol e of asymmetry of the visceral part of female reproductive system in t he formation of EIHA in onto- and phylogenesis. Possible mechanisms of self-organization of the polar functional systems are discussed under evolutionary aspect.
