Although estrogen can induce LH hypersecretion in ovariectomized (0~x1 rats, the magnitude and duration of the LH surge are invariably far less than those of the preovulatory LH surge in cycling rats. Recently, the crucial roles of hypothalamic nitric oxide (NO) and neuropeptide Y (NPY) in the induction of LHRH and the LH surge have been recognized.
