Abstract
The acute effects on sexual behavior of oxazepam (16–64 mg/kg), chlordiazepoxide (8–64 mg/kg), chlorpromazine (2–8 mg/kg), andd-amphetamine (0.8–3.2 mg/kg) were examined in intact male and female golden hamsters (Mesocricetus auratus). Intraperitoneal injections were given 45 min before the first behavioral test. In 10-min tests lordosis was observed in estrous females both before and after copulation, and mounts, intromissions, and ejaculations were observed in males. Dose-response related decrements in male sexual behavior were observed following chlorpromazine and chlordiazepoxide. All dose levels of oxazepam depressed male sexual behavior. The highest dose of chlordiazepoxide and oxazepam attenuated the onset of female sexual behavior, and all dose levels reduced postcopulatory lordosis durations. Amphetamine did not interrupt either male or female sexual behavior, and chlorpromazine disrupted male but not female behavior.
