Figure 1 Urinating to dominance and mating success. Dominant males, with large and muscular bladders (B), store and release a large amount of urine [11–13] with high concentrations of 20α- and 20β-pregnanetriol 3-glucuronates (20 α-PG and 20 β-PG) that are known to stimulate the maturation induction hormone, 17,20β-P, in females [4]. Subordinate males have smaller bladders (b). Current Biology 2014 24, R843-R845DOI: (10.1016/j.cub.2014.08.001) Copyright © 2014 Elsevier Ltd Terms and Conditions
