Urinary testosterone metabolite levels on bonobos: A comparison with chimpanzees in relation to social system
Tijdschriftbijdrage - Tijdschriftartikel
Bonobo (Pan paniscus) social structure is characterized by partial female dominance, in contrast to the male dominated chimpanzee (Pan troglodytes) society. Furthermore, female bonobos exhibit more overt aggressiveness and a prolonged period of proceptivity during menstrual cycle compared to chimpanzees. Since dominance, aggressiveness and proceptivity are suggested to relate to high T levels, we expected T concentrations of bonobo females to be high. To test this, urinary T metabolite concentrations (measured by immunoreactive 5alpha-androstane- 17alpha-ol-3-one) were determined, which reliably reflect T status in both species.
