2. 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).
