  • Title: Effects of stereoselective 5-HT1A agonists on male rat sexual behavior.
    Author: Ahlenius S, Larsson K, Arvidsson LE.
    Journal: Pharmacol Biochem Behav; 1989 Jul; 33(3):691-5. PubMed ID: 2587610.
    Abstract:
    The effects on male rat sexual behavior of some new stereoselective 5-HT agonists, related to 8-OH-DPAT, are presented. It was found that (+)cis-8-hydroxy-1-methyl-2-(di-n-propylamino) tetralin (8-OH-MeDPAT), as well as (-)trans-2-(2-hydroxyphenyl)-N,N-di-n-propylcyclopropylamine (2-OH-DCPA), and its 3-hydroxy-phenyl analog (3-OH-DCPA), stereoselectively facilitated the male rat sexual behavior, as evidenced by a decrease in the number of intromissions preceding ejaculation, and a shortening of the ejaculation latency. For the former two compounds, studied in further detail, the potency and efficacy appear to be of the same magnitude as previously found for 8-OH-DPAT. The results demonstrate specific 5-HT receptor involvement in the mediation of male rat sexual behavior.
