Objective: To determine how the sexual behavior changes in the stagnation of Liver Qi syndrome and whether the alterations of monoaminine system is involved. Furthermore, whether Chinse Herb Calming Liver to Disperse Qi decoction can recover these changes. Methods: Provoked male rats by clamping their tails to make animal model and overiectmized female rats as stimulus animals in sexual behavior test. Flurophotometry was applied to measure Norepinephrine(NE), Dopamine(DA) and 5-Hydroxy tryptmine(5-HT) and NE in isolated corpus cavernosum. Results: NE and 5-HT in brain stem of the model groups in creased comparing with the control group not only directly but also indirectly provoked groups, and NE in isolated corpus cavernosum increased too(P<0.02-0.001), coincidence with these changes, the latency of intromittions and ejaculations of model groups lengthened and the numbers decreased. But the latency of mounts shorterned and the numbers increased (P<0.01-0.005). In Chinese Herbal administration groups, a
