Erectile dysfunction (ED) is associated with a previous diagnosis of psoriasis, according to a study published in The Journal of Sexual Medicine (2012;9:130-135).

Shiu-Dong Chung, MD, of the Far Eastern Memorial Hospital in Taipei, Taiwan, and colleagues conducted a case-control study to evaluate the association between ED and a previous diagnosis of psoriasis in 4,606 subjects with ED and 13,818 control subjects.
