Abstract
The frequency of sexual interactions between oppositely-sexed pairs of gorillas tested in the laboratory was directly related to the frequency of male aggression directed toward the female. The data suggest that male aggression stimulated female presenting and copulation, and accounted for mating temporally dissociated from the periovulatory period. Among the great apes tested in the laboratory, the male primarily accounts for mating that is unlikely to contribute to reproduction.
