Toxic chemicals in the environment harm our ability to reproduce and negatively affect pregnancies.  Many chemicals that pregnant women absorb or ingest from the environment can cross the placenta to the fetus.

The scientific evidence over the last 15 years shows that exposure to toxic environmental agents before conception and during pregnancy can have significant and long-lasting effects on reproductive health, as outlined below in the Committee Opinion from the American College of Obstetricians and Gynecologists (ACOG). In addition, the following provides additional resources for providers and patients on environmental toxic agents and reproductive health.

Committee Opinion: Exposure to Toxic Environmental Agents (September 23, 2013)

The Committee on Health Care for Underserved Women, ACOG, developed a Committee Opinion (#575) on Exposure to Toxic Environmental Agents in conjunction with the American Society for Reproductive Medicine (ASRM) and the University of California, San Francisco Program on Reproductive Health and the Environment.

Reducing exposure to toxic environmental agents is a critical area of intervention for obstetricians, gynecologists, and other reproductive health care professionals. Patient exposure to toxic environmental chemicals and other stressors is ubiquitous, and preconception and prenatal exposure to toxic environmental agents can have a profound and lasting effect on reproductive health across the life course. Many environmental factors harmful to reproductive health disproportionately affect vulnerable and underserved populations, which leaves some populations, including underserved women, more vulnerable to adverse reproductive health effects than other populations.

ACOG and ASRM join leading scientists and other clinical practitioners in calling for timely action to identify and reduce exposure to toxic environmental agents while addressing the consequences of such exposure.

This program provides a number of resources, including educational materials for patients and their families, multiple examples regarding obtaining an exposure history, and a compilation of professional society policy statements calling for regulatory and other efforts to address exposure to toxic chemicals.

Association of Occupational and Environmental Clinics (AOEC), Pediatric Environmental Health Specialty Units 
The AOEC is a network of investigators across the United States who support clinical capacity related to environmental health. The Pediatric Environmental Health Specialty Units respond to requests for information throughout North America regarding prevention, diagnosis, management, and treatment of environmentally-related health effects in children and, as such, are poised to serve as a resource for obstetricians and gynecologists in recognition of the inextricable relationship between reproductive and pediatric health. Occupational Medicine Programs at regional academic centers can serve as a resource for evaluating occupational exposure to chemicals.
