This article explores the role of the hormone relaxin in the mechanisms of preterm labor. The functions of relaxin in the female body during pregnancy are examined, including its impact on the cervix, uterus, and birth canal tissues. The main mechanisms of preterm labor associated with elevated levels of relaxin are described, as well as its role in inflammatory processes and stress responses. The article also discusses current diagnostic methods, including the use of relaxin levels to predict the risk of preterm labor. Perspectives on the use of relaxin as a biomarker and therapeutic target for the prevention of preterm labor are also considered.
