МОРФОМЕТРИЧНІ ПАРАМЕТРИ УТВОРІВ ЧОЛОВІЧОЇ ПРОМЕЖИНИ ПЛОДІВ

Introduction. In recent years, Ukraine has observed a steady trend towards an increase in the level of congenital pathology of the perineal area. This is mainly manifested in the form of anorectal defects and malformations of the external genitalia, the localization of which topographically corresponds to the excretory and urogenital areas. A thorough study of the prenatal processes of perineal morphogenesis will allow us to identify the anatomical prerequisites for the development of perineal defects, understand the mechanisms of morphological processes of their formation and will become the basis for the development of new and improving existing methods of their surgical correction.The purpose of the study is to obtain and analyze using statistical methods the morphometric parameters of male perineal formations.Material and methods. 35 fetal perineal preparations were used for the study. The research material was divided into seven groups of five preparations, respectively, for each of the seven months of the fetal period - from the 4th to the 10th.Research results. Analyzing the dynamics of changes in the morphometric parameters of the main distances between the topographic and anatomical landmarks of the male perineum during the fetal period of ontogenesis, we established a certain unevenness in the intensity of their increase. As a result, we established periods of accelerated and slowed-down increase.Analysis of the sequence of changes in morphometric indicators of distances indicates the presence of periods of accelerated increase, which correspond to certain periods, which is confirmed by statistical analysis of the Mann-Whitney U-Test between independent samples of morphometric indicators of the corresponding months, which revealed statistically significant differences between them in periods of accelerated growth of indicators (p≤0.05). Accordingly, the presence of periods with slow growth of morphometric indicators is confirmed by their analysis using the Mann-Whitney U-Test, which indicates the absence of statistically significant differences between them.Conclusions. 1. We have established the main distances between the formations of the male perineum, by which it is possible to characterize the harmony of its development: a. The distance between the center of the perineal body and the tip of the coccyx; b. The distance between the center of the perineal body and the anterior edge of the bulbospongiosus muscle; c. The distance between the center of the perineal body and the points of interweaving of the fibers of the gluteal cavernous muscle; d. The distance between the center of the perineal body and the scrotum; e. The distance between the anterior edge of the bulbospongiosus muscle and the scrotum; f. The distance between the anterior edge of the bulbospongiosus muscle and the scrotum; g. The distance between the anterior edge of the pubic symphysis and the tip of the coccyx; h. Distance between the ischial tubercles; i. Distance between the ischial tubercle and the top of the coccyx; j. Distance between the ischial tubercle and the ischial tubercle; k. Distance between the ischial tubercle and the anterior edge of the bulbospongiosus muscle. 2. As a result of the statistical analysis of the change in the intensity of the morphometric parameters of the proposed distances, we established periods of accelerated and slowed down their development.
