Abstract:
Centrally administered doses of the tripeptide corticoliberin fragment CRF(4-6) (Pro-Pro-Ile) suppressed mating behavior in male rats. Doses of 1 and 2 microg of the tripeptide produced dose-dependent increases in the latent periods of mounting, intromission, and ejaculation. Changes in measures of sexual behavior demonstrated that the corticoliberin fragment CRF(4-6) suppressed both sexual motivation and sexual performance.
