Истмико-цервикальная недостаточность (ИЦН) является одной из наиболее серьезных причин невынашивания беременности и характеризуется укорочением шейки матки, развивающимся на фоне активации сократительной активности матки (САМ), которые лежат в основе патогенеза преждевременных родов (ПР). Однако известны случаи, когда при выраженном укорочении шейки матки родовая деятельность не развивается, и наоборот, при не выраженном ее укорочении – беременность досрочно прерывается, что определяет поиск новых механизмов формирования ПР, к числу которых относится модулирующее влияние пола плода на процессы гестационной перестройки в материнском организме. Цель: изучение особенностей сократительной активности правых и левых отделов матки у пациенток с ИЦН и неосложненной беременностью и оценить характер течения гестационного периода и исходы родов в зависимости от половой принадлежности плода Методы. Обследовано 146 пациенток с функциональной формой ИЦН и 138 – с физиологической беременностью. Для изучения характера САМ использовали механогистерографию во II и III триместрах беременности. Результаты. Установлено, что при ИЦН у беременных с мужским полом плода, у которых выявлена более высокая частота ПР, преобладала двусторонняя САМ, тогда как при физиологической гестации, доминировавшей у беременных с плодами женского пола, выявлены односторонние маточные сокращения. Заключение. Для ИЦН характерна функциональная симметрия в миометрии, преобладающая в случае мужского пола плода и приводящая к повышению внутриамниального давления и к динамике со стороны шейки матки, тогда как для ФБ характерна функциональная асимметрия, обусловливающая сохранность шейки матки и более выраженная при вынашивании плодов женского пола.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to study the features of contractile activity of the right and left sides of the uterus in patients with isthmiccervical insufficiency and uncomplicated pregnancy and to assess the nature of the gestational processes and labor outcomes depending on the sex of the fetus. Materials and Methods: a total of 146 patients with the functional form of isthmic-cervical insufficiency and 138 with uncomplicated pregnancy were examined. To study the nature of uterine activity of the right and left sides of the uterus, mechanohysterography was performed in the II and III trimesters of pregnancy. Results: in isthmic-cervical insufficiency in pregnant women with male fetuses with a higher incidence of preterm labor, bilateral uterine contractions predominated, whereas in uncomplicated pregnancy (dominated in pregnant women with female fetuses), unilateral (mainly right-sided) uterine contractions were detected. Conclusion: isthmic-cervical insufficiency is characterized by the predominance of functional symmetry in the myometrium, predominant in the case of the male fetus and leading to an increase in intraamniotic pressure and to dynamics from the length of the cervix, whereas physiological pregnancy is characterized by functional asymmetry, causing the preservation of the lower segment and the length of the cervix and more pronounced when bearing female fetuses.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>истмико-цервикальная недостаточность</kwd><kwd>неосложненная беременность</kwd><kwd>сократительная активность матки</kwd><kwd>функциональная стереоизомерия миометрия</kwd><kwd>пол плода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>isthmic-cervical insufficiency</kwd><kwd>uncomplicated pregnancy</kwd><kwd>uterine contractile activity</kwd><kwd>functional stereoisomerism of the myometrium</kwd><kwd>the sex of the fetus</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Беглов Д.Е., Артымук Н.В., Новикова О.Н., Марочко К.В., Парфенова Я.А.
