Ambisexual behavior with male-male anal penetration in male rhesus monkeys

  title={Ambisexual behavior with male-male anal penetration in male rhesus monkeys},
  author={J. Erwin and Terry L. Maple},
  journal={Archives of Sexual Behavior},
One pair of male rhesus monkeys reared in the laboratory with exclusive social access to each other during their second year of life were observed to display reciprocal mounting with anal penetration on several occasions. Their mounts were of comparable duration to those which have been observed in matching heterosexual pairs, by contrast with the brief mounts which are often observed in dominance interactions. The postures exhibited by the mounted male resembled those typical of females during… 

Homosexual behaviour and female‐male mounting in mammals—a first survey

Information from the literature is given on the presence or absence of homosexual behaviour and female-male mounting in 125 species of mammals, both captive and wild. Such behaviour occurs in the

Homosexual behavior in a laboratory group of stumptail monkeys (Macaca arctoides): Forms, contexts, and possible social functions

Observations of stumptail monkeys revealed frequent prolonged, intensive genital stimulation between individuals of the same sex, both males and females, adults and infants, suggesting that homosexual and heterosexual encounters function as training for adult sexual roles, and that homosexual behavior is a basic primate pattern not exclusive to man.

Heterosexual experience and isosexual behavior in laboratory-housed male stump-tailed macaques (M. arctoides)

Three feral-born male stump-tailed macaques were housed together for 9 years from prepubertal age and pair-tested with each other and with females for the first time in their adult lives, revealing that these males preferred females as sexual partners.

Male Homosexual Behaviour Accompanied by Ejaculation in a Free-Ranging Troop of Japanese Macaques (Macaca fuscata)

Observed cases of male-male mountings with ejaculation among a free-ranging troop of Japanese macaques are analyzed and it is examined whether this behaviour can be classified as ‘sexual behaviour’.

Case Report of Male-Male Sexual Interaction Involving Ejaculation Observed in a Wild Population of Stump-Tailed Macaques (Macaca arctoides) in Thailand

A very rare case of ejaculation in the context of male-male mounting in wild stump-tailed macaques in Khao Krapuk Khao Taomor Non-hunting Area, Thailand is reported.

Homosexual behavior in primates: A review of evidence and theory

Exaptation is suggested as a theoretical framework for interpreting homosexual behavior and it is concluded that future consideration of sexual selection among primates should address homosexual components of this process.

Sex hormones and male homosexuality in comparative perspective

Animal research has demonstrated the modifiability of sex-dimorphic mating behavior by hormone and brain manipulation, especially in subprimate mammals, and has led to radical attempts at treating

A call is made to researchers working with non-human primates to test and extend the findings from the three studies presented, which are studying the sexually dimorphic behaviour of children of sexually atypical parents.

Cross-species and cross-cultural contributions to understanding homosexual activity.

The data suggest that preferential or obligatory homosexuality in adulthood, in the presence of available and receptive heterosexual partners, is qualitatively rather than quantitatively distinct from all other manifestations of homosexual activity, and that quantitative incidence rating scales obscure meaningful understanding of this dimension of homosexual behavior.



Male-Female, Female-Female, and Male-Male sexual behavior in the stumptail monkey, with special attention to the female orgasm

Examination of the behavior of females during heterosexual coitus suggests that female orgasms also occur during heterosexual interactions, and indicates that females are evidently capable of taking active roles in coitus, and their potential for orgasm is much more similar to that of males than previously thought.

Initial heterosexual behavior of adolescent rhesus monkeys (Macaca mulatta)

The first heterosexual encounters of twelve 3-year-old rhesus monkeys, six of each sex, are described, which demonstrated qualitatively species-typical patterns of sexual behavior.

Responses of Rhesus Monkeys to Reunion after Long-Term Separation: Cross-Sexed Pairings

RS monkeys were reunited with other-sexed peers with which they had been paired for 6 mo. during early adolescence, and it was apparent that heterosexual attractiveness in general was not based exclusively on familiarity.
