Effects of Metformin on Sperm Parameters in Mice: as a model for human being


Background:Metformin is anti-hyperglycemic effect due to decrease of hepatic glucose production. Another effect, leading decrease insulin resistance, regarded a safe drug, treatment of choice for overweight.Objective:To investigate the effects of 3 concentration of MF administered orally to male mice on sperm parameters as model for human being.Materials and Methods:In current study, 80 male mice were taken with age ranging between 1.5-2 month and weights ranging between 25-30 grams males classified into four groups of a control group (G1) and treated group (G2, G3 and G4) doses of MF were employed, 0.2, 0.4, 0.6 mg/mice daily to groups, given orally for 6 weeks and then the animals were scarified.ResultsResults have revealed a significant difference (P < 0.05) in sperm concentration for 3 groups compared to G1 group. Progressive motility (%) appeared with significant difference (P< 0.05) for G3 group as compared to other treated and G1 group. Furthermore, the result illustrated a significant decreased (P< 0.05) in the abnormal sperm morphology for G3 group compared with treated and control. However, sperm agglutination (%) confirmed that the G3 group exhibited highly statistical significant decrease (p≤0.001) compared to G1, G2 and G4.ConclusionsFrom results of the present study, it was concluded that the administration of MF doses reduce sperm concentration .while, 0.4mg dose improve certain sperm parameters.
