Although numerous studies in rats have demonstrated an influence of serotonin (5-HT) on male copulation, no studies have yet to demonstrate whether such a relationship exists in primate species. The present study sought to characterize 5-HT influences on male copulatory behavior of rhesus monkeys by using three different 5-HT agonists: a full 5-HT1A(More)
Research has indicated that serotonin (5-HT) is involved in regulating male sexual behavior in rodent, as well as primate species. The present study was designed to further characterize 5-HT influences on male sexual behavior of rhesus monkeys. Experiment 1 examined the effects of 5-HT1A and 5-HT1C/1D receptor stimulation on penile erections and yawning(More)
Although numerous studies in nonhuman primates have demonstrated an influence of cocaine on behavior, no studies have yet examined whether cocaine affects sexual behavior in nonhuman primates. The objective of the present study was to examine the acute effects of cocaine on male copulatory behavior of rhesus monkeys. Administration of cocaine produced(More)
