[Characteristics of the functional state of different sections of the autonomic nervous system and their role in the pathogenesis of oligomenorrhea].

Analysis of the clinical picture of oligomenorrhea and of the results of studies of the function of various sections of the autonomic nervous system (ANS) in 58 patients of a reproductive age has revealed differences in these functions, related to the time of menstrual disorders onset. Oligomenorrhea patients with menarche complained of cardiovascular, respiratory, and emotional-motivational disorders, examinations have revealed in them dysfunctional disorders and reduced reserve potentials of both ANS sections. In oligomenorrhea patients in whom the condition developed at the age of 18-25 after a period of regular menstruations the effects of various stress factors resulted in reduction of the functional activity of the ergotropic (sympathoadrenal) section of the ANS. Differences in the pathogenetic mechanisms of oligomenorrhea development in the two groups of patients are discussed.
