A Large-scale, Prospective Cohort Study Was Conducted to Explore the Association Between Environmental Exposure and Behavioral Factors and Infertility (the Success Rate of Assisted Reproductive Technology)
The Third Xiangya Hospital of Central South University
5,000 participants
Apr 1, 2025
INTERVENTIONAL
Conditions
Summary
The aim is to explore the reasons for the failure of assisted reproductive technology (ART) in infertile patients in Hunan Province and seek ways to improve the success rate of ART. The study will focus on how environmental exposure (such as environmental pollutants related to plastic products) and lifestyle and social factors affect the success rate of ART in infertile patients. In order to explore these issues in depth, the study plans to collect 5,000 samples (male: female ratio 1:1), screen the research subjects from infertile patients who visited Xiangya Third Hospital in Changsha, Hunan Province, and establish a large-scale, prospective infertility patient cohort. By collecting multi-faceted information of the research subjects, including sociodemographic characteristics, lifestyle, basic health status, etc., and conducting long-term follow-up observations, the ART live birth situation of infertile patients is analyzed. In terms of research methods, a multivariate analysis method will be used to explore the association between various factors and ART success rate, and a risk prediction model will be constructed. In addition, the study also hopes to clarify the specific reasons for the failure of infertile patients to receive ART, provide a scientific basis for clinical decision-making, and provide guidance for the formulation of environmental protection policies and the improvement of public reproductive health literacy. In general, this study, through a large-scale, prospective cohort study, deeply explores the various factors that affect the success rate of ART in infertile patients, and strives to build a risk prediction model in order to improve the success rate of ART and bring more hope to infertile families.
