Abstract
Summary and Conclusions
Effects of chlorpromazine and LSD-25 on sex behavior of 12 male albino rats were studied. Chlorpromazine at 2.5 mg/kg injected 30 minutes before trial and LSD at both 200 γ/kg and 130 γ/ kg injected 5 minutes before trial, reduced the number of copulations preceding ejaculation. Reduction in number of copulations by LSD did not follow the pattern of tolerance described for impairment of rope-climbing by LSD. Rate of copulation on the first trial that chlorpromazine was given was significantly slowed.
