چکیده
Effects of social isolation and crowding on sexual beha,·iour in the rat (Rattus norvegicus).The effects of social isolation and crowding on the sexual behaviour of Sprague Dawley male and female rats (Rattus norvegicus) were investigated. The major housing condition effect was found among social isolates. A significant decrease in their non-copulatory activity was observed in both genders when compared with socially reared animals, but only a similar tendency appeared with respect to their copulatory activity. No clear effects of crowding on the animal's sexual behaviour was found. The importance of social experience during development for a complete sexual display in the adulthood is discussed. The absence of noticeable effects of crowding upon specific sexual patterns, and the influence of high population density upon several physiological systems are also discussed.
