Associated Features Supporting Diagnosis 
Male hypoactive sexual desire disorder is some times associated with erectile and/or ejac-
ulatory concerns. For example, persistent difficulties obtaining an erection may lead a man
to lose interest in sexual activity. Men with hypoactive sexual desire  disorder often report
that they no longer initiate sexual activity and that they are minima lly receptive to a part-
ner’s attempt to initiate. Sexual activities (e.g ., masturbation or part nered sexual activity)
may sometimes occur even in the presence of low sexual desire. Relationship-specific pref-
erences regarding patterns of sexual initiation  must be taken into account when making a
diagnosis of male hypoactive sexual desire di sorder. Although men are more likely to ini-
tiate sexual activity, and thus low desire may be characterized by a pattern of non-initiation,
many men may prefer to have their partner init iate sexual activity. In such situations, the
man’s lack of receptivity to a partner’s initiati on should be considered  when evaluating low
desire.
In addition to the subtypes “lifelong/acquired” and “generalized/situational,” the fol-
lowing five factors must be considered duri ng assessment and diagnosis of male hypo-
active sexual desire disorder given that they may be relevant to et iology and/or treatment:
1) partner factors (e.g., partne r’s sexual problems, partner’s health status); 2) relationship
factors (e.g., poor communication , discrepancies in desire for sexual activity); 3) individ-
ual vulnerability factors (e.g., po or body image, history of se xual or emotional abuse), psy-
chiatric comorbidity (e.g., depression, anxiety), or stressors (e.g., job loss, bereavement);
