Abstract

Objective: This study aimed at investigating the effect of nanoalumina on sex hormones, and fetuses in pregnant rats. Methods: In this study, sixty-four pregnant rats were divided into eight groups. The control and the injection-control group received normal food and water, and 0.5 ml of distilled water, respectively. Treatment groups were treated with 25, 50, 100, 250, 500, and 1000μg/ml concentrations of Nanoalumina from the 7th day until the 18th day of pregnancy. On the 18th day, the rats were investigated in terms of their hormone levels. We evaluated the number of healthy and aborted offspring, as well as fetus size. Results: Nanoalumina caused an increase in progesterone hormones at the concentrations of 250, and 500μg/ml, and a significant reduction in estrogen hormone and aborted fetuses at the concentrations of 250 and 500μg/ ml (p<0.05). The largest and smallest size of fetuses were observed in 500μg/ml and 1000μg/ml, respectively. The highest number of aborted fetuses was observed in the group treated with the 500μg/ml concentration. There was no aborted fetuses with 25, 50,100, control, and injection-control groups. Conclusions: Due to nanoalumina toxicity, it must be used with caution. © 2022, Sociedade Brasileira de Reproducao Assistida. All rights reserved.
