The application of RIAs for the gonadotropins to the study of domestic animal reproduction has depended on the availability of sensitive and specific reagents, automated systems for increased throughput and an awareness of the assay errors. Illustrations are given on the measurement of seasonal, surge and episodic changes in LH secretion and the advantages gained by such investigation are outlined.
