Fetal, Neonatal And Childhood Effects Of In Utero Exposure To PCB And DDE

2007财政年度发表的研究表明，尽管先前在人类和动物中有暗示性的结果，但六氯苯（优势比1.1,95% CI 0.6-2.0）、七氯环氧化物（优势比1.2,95% CI 0.6-2.6）和-四氯环己烷（优势比1.6,95% CI 0.7-3.6）都与隐睾症无关。

Work published in FY2007 indicated that, in spite of previously suggestive results in humans and animals, neither hexachlorobenzine (odds ratio 1.1, 95 percent CI 0.6-2.0), heptachloroepoxide (odds ratio 1.2, 95 percent CI 0.6-2.6), nor beta-exachlorocyclohexane (odds ratio 1.6, 95 percent CI 0.7-3.6) were associated with cryptorchidism. Additional work evaluated growth during childhood according to prenatal exposure to DDE. Compared to children whose mothers had the lowest serum concentrations of DDE in the third trimester (less than 15 micrograms per liter), children of mothers with concentrations of at least 60 micrograms per liter were shorter at 1, 4 and 7 years. However, there were no differences in height for children whose mothers had intermediate levels.
