title: Concentrations of luteinizing hormone in ovariectomized ewes and the effect of disturbance, starvation and vascular cannulation.
abstract: Neither routine experimental procedures, including vascular cannulation and venipuncture, nor starvation or disturbance caused significant fluctuations in luteinizing hormone (LH) concentrations in ovariectomized ewes. Samples obtained at 5-min intervals revealed episodic LH releases occurring every 10-35 min. Hourly sampling over 3 days revealed large LH variations but no distinct diurnal variation.
