From: Sexual dimorphism of detrusor function demonstrated by urodynamic studies in rhesus macaques
Pressure flow studies show sexual dimorphism in rhesus macaques. Studies of subjects with demonstrated micturition reflex activation and voiding were performed in male (n = 9) and female (n = 19) rhesus macaques. The bladder pressure at voiding onset (Pvoid) (a), peak pressure (Ppeak) (b), and change in bladder pressure from end of bladder infusion to peak pressure (P∆detr) (c) were significantly higher in the males compared to female subjects. There was no difference between the male and female subjects with regards to delay from end of bladder infusion to the onset of voiding (Vdelay) (d), voided volume (Vv) (e), duration of voiding (Vdur) (f), flow rate of voiding (Vflow) (g), and voiding efficiency (VE) (h). The post-void residual volume (PVR) was larger in males compared to the female subjects (i).
