What is Erectile Dysfunction?
The essential feature of erectile disorder is the repeated failure to obtain or maintain erections during partnered sexual activities (Criterion A). A careful sexual history is necessary to ascertain that the problem has been present for significant duration of time (i.e., at least 75% of the time). Symptoms may only occur in specific situations involving certain types of stimulation or partners, or they may occur in a generalized manner in all types of situations, simulation, or partners.*
