The possible degradation of GnRH by intact pituitary tissue was investigated. Trypsin-, collagenase- and mechanically dispersed pituitary cells in culture and fresh pituitaries cut into eight segments were incubated with specifically tritiated GnRH or unlabeled GnRH which were detected by HPLC and RIA in incubation media. Degradation of GnRH could not be detected by either method during incubations with any of the pituitary cell cultures or fresh tissue. The results suggest that pituitary degradation is not involved in the regulation of circulating levels of GnRH.
