Abstract Objective: To explore the influence of lead exposure on menstrual disorders, spontaneous abortion, high-quality embryo in women in women subjected to assisted reproductive technology. Methods: Women who were subjected to assisted reproductive technology for female infertility were recruited. The blood lead concentration was measured by graphite oven atomic spectrophotometer. Results: The average lead concentration was 30.98 (0-319.74) μg/L. The blood lead concentration exceeded the normal range in 21 (4.49%) women. No statistical relationships between the blood lead concentration with the incidence of menstrual disorders and spontaneous abortion as well as the good quality embryo rate were found. Conclusion: This study suggests that high concentration of blood lead may have no relationship with the incidence of menstrual disorders and spontaneous abortion as well as the good quality embryo rate. Large scale study is need to verify whether the lead pollution could result in the damage on female reproduction function and their offspring.
