This article explores the role of relaxin and matrix metalloproteinases (MMPs) in the mechanisms of preterm labor. The molecular mechanisms through which these molecules influence the structural changes in the uterine and cervical tissues, which are related to the onset of labor, are discussed. Special attention is given to the relationship between relaxin levels and MMP activity, as well as their role in preparing the female body for labor. The article also addresses modern approaches to the diagnosis and treatment of preterm labor based on the use of these molecules as biomarkers. The findings of this research open up new prospects for the development of effective methods for the prevention and treatment of preterm labor.
