title: Induction of LH surges by continuous infusion of LH-RH1.
abstract: Preovulatory LH surges were measured in cannulated proestrous rats. Such LH peaks were also obtained by infusing pentobarbital-blocked animals with LH-RH for periods of up to 20 h; this suggested that the pituitary LH stores were exhausted. However, the total amount of LH secreted appeared more or less determined by the LH-RH dose, indicating that the size of the releasable LH pool is not fixed.
