Effect of Short-Term Castration and Starvation upon Hypothalamic Content of Luteinizing Hormone-Releasing Hormone in Adult Male Rats

Abstract

A sensitive and specific radioimmunoassay for hypothalamic LH-RH has been described. Within 7 days after castration there is a significant decline in hypothalamic content of LH-RH in adult male rats. Total starvation for 7 days does not affect hypothalamic content of LH-RH in either intact or castrated rats.
