Effect of monosodium glutamate (MSG) oral administration on relative levels of female sex hormones during oestrus phase in female rats. Comparing the mean relative levels of serum oestrogen (pg/ml) and progesterone (ng/ml) between control and MSG-treated group. The chemiluminescent immunoassay (Beckman coulter Access II, USA) was used. Data were presented as mean ± SEM, (n= 6 rats per group). Student’s t-test was used to compare between MSG-treated group and control, and differences were considered significant at ∗p < 0.05 compared to control group.
