Cadmium induces spontaneous abortion by impairing endometrial stromal cell decidualization.

Cadmium (Cd) is a toxic heavy metal with a high propensity to accumulate within the body, and Cd accumulation has been shown to cause organ damage. However, it is unclear whether Cd accumulation is a cause of impaired decidualization, which induces to spontaneous abortion (SA). In this study, we found that the decidual Cd concentration was increased in patients with SA and positively correlated with the occurrence of SA.
