Figure 2
(a, b) Course of arginine-vasopressin (AVP) in (a) the systemic and (b) cavernous blood of healthy men (HM) and in a cohort of patients with erectile dysfunction (ED) at different stages of sexual arousal, exemplified by penile flaccidity (Fl), tumescence (Tu), rigidity (Ri, attained only by the healthy subjects) and detumescence (Det). Data are displayed as in ng vasopressin/l plasma. Asterisk (): concentrations are significantly different from each other; §: concentration of AVP is significantly different from the concentration at flaccidity.
