AMENDED Resolution 126 (A-80), "Professional Awareness of Hazards to Pregnant Workers," urged the American Medical Association to heighten awareness of physicians about circumstances associated with the reproductive health of workers and to familiarize them with the Guidelines on Pregnancy and Work, published by the American College of Obstetricians and Gynecologists. The adopted resolution was referred through the Board of Trustees to the AMA Council on Scientific Affairs.

The Council appointed an Advisory Panel on Reproductive Hazards in the Workplace to prepare a report. The panel recommended, with Council concurrence, that the report should consider all phases of the reproductive cycle, including male and female fertility, mutagenicity, teratogenicity, fetotoxicity, and postnatal effects. The task was divided into three projects: (1) effects of physical forces on the reproductive cycle, (2) effects of toxic chemicals on the reproductive cycle, and (3) effects of pregnancy on work performance.

The following report should be a
