In 1984, J. David Erickson and his research team published the results of a study titled 'Vietnam Veterans' Risks for Fathering Babies with Birth Defects' that indicated that Vietnam veterans were at increased risk of fathering infants with serious congenital malformations, or birth defects. Researchers at the Centers for Disease Control (CDC) in Atlanta, Georgia, conducted the study to address Though the study's results were inconclusive, the study was one of the first to document a possible association between Vietnam War service and spina bifida, a lower back birth defect in which the spinal cord does not form properly. Later research established the links between Agent Orange exposure and various birth defects and led the US Department of Veterans Affairs to offer disability compensation for Vietnam veterans and their families who were affected by Agent Orange exposure.

In 1988, the US Centers for Disease Control published 'Health Status of Vietnam Veterans III. Reproductive Outcomes and Child Health,' which summarized part of the results of the Vietnam Experience Study commissioned by US Congress to assess the health of US Vietnam veterans. They published the article in the Journal of the American Medical Association. The most heavily used herbicide in the Vietnam, Agent Orange, had previously been found to contain a contaminant linked to birth defects in rats. By comparing the health of Vietnam War veterans exposed to Agent Orange in Vietnam to those serving elsewhere, researchers determined that veterans who served within Vietnam more frequently reported health problems for themselves and their children, but were not at increased risk of fathering children with birth defects. Later studies overturned that latter conclusion and definitively linked Agent Orange exposure to later birth defects. The article represented the first attempt by the US government to ascertain the full risk of birth defects posed by Agent Orange, which eventually culminated in 1997 when the US Veterans Administration compensating the families of Vietnam veterans for Agent Orange-related birth defects.
