A Large-Scale Prospective Cohort Study on the Association of Environmental Exposures and Behavioral Factors With Infertility and Assisted Reproductive Technology (ART) Success Rates
This large-scale study aims to understand how everyday environment and lifestyle may affect the success of fertility treatments like IVF. The main idea is that exposure to certain environmental chemicals (e.g., from plastics or air pollution) and personal habits (e.g., diet, stress) could be linked to whether these treatments result in a successful pregnancy and live birth. The study will follow approximately 5,000 couples undergoing fertility treatment in Hunan, China. Participants will answer questionnaires about their health, lifestyle, and environment and provide small biological samples (like blood and urine) during their standard treatment process. Their treatment outcomes will be tracked anonymously.The goal is to identify factors that might lower the chances of treatment success. This knowledge could help future patients and doctors make informed decisions and could guide public health advice on reducing potential risks. The study has received ethical approval, and all participant information will be kept strictly confidential.
