Following the observation by Benkert (1972), that L-DOPA influences the sexual behaviour of rats, we studied the L-DOPA (5.6 mg/kg), I.P. induced sexual behaviour in male Wistar rats (average weight of 350 g), in relation to side-effects on blood hormone levels and via indirect side-effects of the sexual partner. A percentage of time spent in sexual behaviour was achieved by counting the number of sexual responses over a post injection hour. A camera set to record 15 slides per minute was placed in the animal behaviour room and thereby eliminated the necessity of distracting human observers. This film record also allowed a more slow and careful analysis by several different researchers at their own time convenience. A record of individual animal behaviour changes with time was also possible. L-DOPA brought about no definite change in amount of time spent in overall sexual activity, though it may have been responsible for an increase in the amount of time spent in mounting.
