title: The effects of aluminium ingestion on reproduction and postnatal survival in rats.
abstract: Aluminium nitrate was tested for its effects on reproduction, gestation, and lactation in Sprague-Dawley rats, at dosages of 0, 180, 360 and 720 mg/kg/day. Mature male rats were treated orally for 60 days prior to mating with mature virgin female rats treated for 14 days prior to mating with treatment continuing throughout mating, gestation, parturition, and weaning of the litters. One-half of the dams in each group were killed on day 13 of gestation and the remaining dams were allowed to deliver and wean their offspring. Postnatal development was monitored. No adverse effects on fertility or general reproductive parameters were evident at doses employed in these studies. However, the survival ratios were higher for the control group. Moreover, a dose-dependent delay in the growth of the living young could be observed in aluminium treated groups. Therefore, it would seem that high amounts of aluminium should not be ingested during the periods of gestation.
