*'''<span style="color:#ff0000">3 phases of detumescence:</span>'''
*# '''<span style="color:#ff0000">Transient intracorporeal pressure increase, indicating the beginning of smooth muscle contraction against a closed venous system</span>'''
*# '''<span style="color:#ff0000">Slow pressure decreases</span>''', suggesting a slow reopening of venous channels with resumption of the basal level of arterial flow
*# '''<span style="color:#ff0000">Fast pressure decrease</span>''' with fully restored venous outflow capacity
*'''<span style="color:#ff0000">Detumescence after erection may be a result of (3):</span>'''
*# '''<span style="color:#ff0000">Cessation of NO release</span>'''
*# '''<span style="color:#ff0000">Breakdown of cGMP by PDEs</span>'''
