PRETERM LABOR IN PREGNANT WOMEN UNDERGOING IN VITRO FERTILIZATION: A LITERATURE REVIEW

Abstract

Preterm labor is a relevant complication in pregnancies resulting from in vitro fertilization (IVF), presenting considerable risks for both mothers and newborns. This article reviews the literature on the incidence of preterm birth in pregnant women undergoing IVF, identifying risk factors such as multiple pregnancies, advanced maternal age, and associated medical complications. The systematic review, based on studies published between 2010 and 2023, explores the effectiveness of management strategies, such as single embryo transfer and preventive interventions, including the use of progesterone and cervical cerclage. Intensive prenatal care is highlighted as fundamental to reduce prematurity rates. Despite the advances, there are gaps in research on the impact of different IVF protocols, requiring further investigations to optimize care for high-risk pregnant women.
