“…Of particular concern were adverse reproductive outcomes presumably caused by exposure to potentially hazardous substances encountered during deployment. In 1994, the U.S. General Accounting Office identified 21 possible reproductive toxicants and teratogens that were present during the 1990–1991 Gulf War, which included agents present in smoke from the Kuwaiti oil well fires, soil samples, and pesticides (United States General Accounting Office, August 1994; Warden, 1996; Smith et al, 2002). Most epidemiologic studies of this issue in the 1990s showed inconclusive or negative results (Penman et al, 1996; Cowan et al, 1997; Araneta et al, 2000; Ishøy et al, 2001; Doyle et al, 2004; Werler et al, 2005; Doyle et al, 2006; Wells et al, 2006) although some have suggested significantly more self‐reported ectopic pregnancies and spontaneous abortions in Gulf War veterans conceiving after but not during the war (Araneta et al, 2004).…”
