Serum luteinizing hormone (LH) levels in all experimental groups. The data were presented as Mean ± S.E.M. Mean with different superscripts are significantly different aP < 0.01 versus negative control group (CO) and bP < 0.01 versus positive control group (PC). CO = Negative control group administered with vehicle (corn oil). PC = Positive control group administered with BPA at 10 mg/kg body weight. TH = Tualang honey group administered with Tualang honey at 200 mg/kg body weight + BPA at 10 mg/kg body weight. THC = Tualang honey control group administered with Tualang honey at 200 mg/kg body weight.
