Structural defects in the rat brain associated with maternal exposure to ammonium perchlorate accompanied reductions in circulating levels of thyroid hormone in the dam and the fetus. The magnitude of the effect was small relative to other thyroid hormone disruptors, but his was due to the lack of sufficient bioavailability of perchlorate to the nursing neonate. When pups were administered perchlorate directly for the first 6 days of life or if perchlorate was administered under conditions of maternal dietary iodine deficiency, very large brain malformations were induced.
