Step 1. NORMAL HUMAN PRENATAL DEVELOPMENT
Circled numbers in the gray bars indicate the number of prenatal events listed for each week of human development. Click on a number to see the list of events.

Step 2. LOW-DOSE EFFECTS ON LAB ANIMALS
Choose one or more chemicals (right) to see the effects of low-dose exposure in lab animals. Colored bars will appear, with circled numbers indicating the number of studies in which exposure began during that week of development. The length of the colored bar reflects the duration of exposure across all studies in the row. Click on a number to see the effects of exposure.
