Effect of short-term castration and starvation upon hypothalamic content of luteinizing hormone-releasing hormone in adult male rats.
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.
