Objective: Investigate the effects of diabetes and treatment with quercetin on the maternal reproductive performance and impact on foetal growth.
Study design: A total of 32 female Wistar rats were distributed into four groups: non-diabetic (G1); non-diabetic treated with quercetin (G2); diabetic (G3) and diabetic treated with quercetin (G4). At day 21 of pregnancy, each rat was anesthetized and humanely killed for laparotomy; was observed reproductive performance, foetal and placental weights and the placental index. Maternal and foetal data were analysed by ANOVA followed by the Tukey test. Foetal weight classification was assessed by Goodman’s test.
Results: Diabetes and diabetes treated with quercetin caused placentomegaly an increased placental index and small foetus rates for pregnancy age.
Conclusion: Quercetin, administered to pregnant diabetic rats, controlled glucose levels and promoted weight gain compared to untreated diabetic rats, but it did not improve reproductive performance or foetal or placental development.
