About this study

Official title: Adverse Effects and Mechanism of Environmental Endocrine Disrupting Chemicals on Female Reproductive health--the Peking University and Environment Reproductive Health Cohort

Infertility is a disease that seriously affects the physical and mental health of women of childbearing age. The incidence of infertility has been increasing in recent years. Studies have shown that the occurrence of infertility may be related to environmental endocrine disrupting substances. This project was designed to establish a cohort study on environmental endocrine disrupting substances and in vitro fertilization (IVF) treatment, collect blood, urine, semen, follicular fluid, granulosa cells, chorionic decidua biological specimens, and then follow up on the pregnancy outcomes. The concentration of disrupting substances was detected and then found the associations between environmental endocrine disrupting substances and female reproductive health.
