Causes of Chromosome Breakage and Mis-segregation Affecting Pregnancy and Newborn Health: An Insight into Developing Reproductive Health Preventive Strategies

Abstract

Chromosome abnormalities are a leading cause of pregnancy loss, developmental delays, and birth defects. These abnormalities arise from errors in chromosome structure (breakage) or number (missegregation) during cell division. Understanding the causes of these errors is crucial for developing effective preventive strategies to improve reproductive health. This paper aims to review the known causes of chromosome breakage and mis-segregation, emphasizing their impact on pregnancy and newborn health. It further explores potential preventive strategies for mitigating these risks. A comprehensive literature review was conducted using relevant databases, focusing on studies investigating the causes of chromosome abnormalities, their impact on pregnancy and newborn health, and potential preventive measures. Several factors contribute to chromosome breakage and mis-segregation, including Genetic Predisposition, Environmental Factors (environmental toxins, radiation), Maternal age, Lifestyle Factors (Smoking, alcohol consumption, and obesity), and Cellular Mechanisms. These abnormalities can manifest as various pregnancy complications, including Miscarriage, stillbirth, birth defects, and developmental Delays. The causes of chromosome breakage and mis-segregation are complex and multifactorial. Understanding these factors is crucial for developing effective preventive strategies. These strategies may include genetic counseling, pre-conception health optimization, environmental hazard mitigation, and advancements in assisted reproductive technologies. Further research is needed to identify specific interventions and personalize strategies based on individual risk factors. Addressing these causes and implementing preventive measures can significantly improve reproductive health outcomes and reduce the incidence of chromosome abnormalities affecting pregnancy and newborn health.
