Primate Sexuality: Comparative Studies of the Prosimians, Monkeys, Apes, and Humans
- A. Dixson
The development of sexually dimorphic behaviour and the neuroendocrine regulation of sexual behaviour in the adult female and male and human sexuality in primatological perspective.
The Evolutionary Biology of Human Female Sexuality
- A. Dixson
- 25 September 2008
The author reveals how Estrus, Pair-Bonding, and Extra-Pair Sex have transformed women's sexual identity and shaped the way they view the world around them.

M maternal factors affect reproductive success in both sexes, influencing the age at which offspring mature and begin their reproductive career, and to investigate maternal influences upon growth.
Observations on the Evolution and Behavioral Significance of “Sexual Skin” in Female Primates
- A. Dixson
The chapter explains that sexual skin may have arisen by elaboration of the same type of vulva swelling and pinkness that occurs during estrus in many female prosimians, and suggests that a complementary degree of penile elongation occur in order to facilitate mating behavior in those species, where females have prominent swellings.
Changes in the Secondary Sexual Adornments of Male Mandrills (Mandrillus sphinx) Are Associated with Gain and Loss of Alpha Status
It is demonstrated that male-male competition and rank reversals have remarkable effects upon testicular function, secondary sexual traits, and behavior in the adult male mandrill.
Reproductive Parameters and Maternal Investment in Mandrills (Mandrillus sphinx)

Maternal rank and parity appear to influence reproductive success in female mandrills in Gabon, but there is no apparent differential maternal investment by sex.

Study 5 showed that presence of trunk hair had a marked, positive effect upon women's ratings of attractiveness for both mesomorphic and endomorphic male figures, consistent with effects of sexual selection upon visual signals that advertise health, physical prowess, age, and underlying endocrine condition in the human male.
Observations on the evolution of the genitalia and copulatory behaviour in male primates
- A. Dixson
- 1 November 1987
Comparative studies of genital anatomy and sexual behaviour in male primates show that penile morphology and copulatory patterns tend to be more specialized in species which have a multimale or…
Sperm competition: Motility and the midpiece in primates
The results indicate that sexual selection by sperm competition has influenced the evolution of a specific component of male-gamete morphology, the volume of the sperm midpiece, in primate species with multiple-partner mating systems.
Prolactin and parental behaviour in a male New World primate
It is reported here that in male common marmosets carrying their twin offspring, plasma prolactin levels are five times higher, on average, than in males without infants, which suggests that physical contact may be important in producing the effects.
