The gorilla gives birth to a single offspring every four years (Estes, 1991). The female is usually the one to solicit copulations from the male (Estes, 1991). Mating is usually dorso-ventral, but ventro-ventral (face-to-face) mating does occur (Estes, 1991). Copulatory panting is emitted by the males during mating (Estes, 1991). Immature males might also try to mount preadolescent and adolescent females, the adolescent females have small sexual swellings (Estes, 1991).
