Inflammation, orchestrated by immune cells like neutrophils, plays a crucial role in maintaining homeostasis andprotecting against pathogens. However, during pregnancy, the delicate balance of immune responses is paramountto support fetal development while safeguarding maternal health. Neutrophils, as pivotal contributors to the innateimmune system, significantly influence the inflammatory milieu, yet excessive or dysregulated neutrophil-derivedinflammation can impact pregnancy outcomes. This paper aims to dissect the multifaceted role of neutrophil-derivedinflammation in shaping pregnancy outcomes. It delves into the mechanisms by which neutrophils orchestrateinflammatory responses during gestation and scrutinizes the implications of heightened inflammation on maternalfetalhealth. Specifically, it explores the association between increased neutrophil-driven inflammation and adverseoutcomes such as preterm birth, preeclampsia, intrauterine growth restriction, and fetal developmentalabnormalities. Examining the intricate balance between protective and detrimental roles of neutrophil-derivedinflammation, this review assesses alterations in neutrophil functions, activation pathways, and the release ofinflammatory mediators during normal and pathological pregnancies. Additionally, it evaluates potential regulatorymechanisms governing neutrophil-derived inflammation and identifies putative biomarkers indicative of heightenedinflammatory responses linked to adverse pregnancy outcomes. The clinical implications of understanding theimpact of neutrophil-derived inflammation on pregnancy outcomes are highlighted, emphasizing its significance inobstetric care, prenatal monitoring, and potential therapeutic interventions. Furthermore, this review delineates the critical need for future research avenues focusing on molecular investigations, therapeutic modulation of neutrophildriveninflammation, and longitudinal studies to elucidate the long-term consequences on maternal and fetal wellbeing.In conclusion, unraveling the intricate interplay between neutrophil-derived inflammation and pregnancyoutcomes is imperative. A deeper understanding of these interactions holds promise for informing clinical strategies,improving prenatal care, and ultimately optimizing maternal and fetal health.Keywords: Neutrophil, Inflammation and Pregnancy Outcomes.
