Except group A, the other four groups were implanted with pituitary for modeling. Group C was treated with bromocriptine 1 mg/kg, group D with gastric infusion of KG 4 g/kg and group E with KG 12 g/kg. The treatment lasted 34 days. Serum levels of prolactin (PRL), testosterone (T), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estrogen (E2) were detected before and after treatment and the differences between groups were compared. [ Results ] Serum PRL and T levels were increased and LH, FSH and E2 levels decreased in group B (P
