Population:
All 22 patients had a chronic SCI lasting a
median (range) of 63 (7–156) months; 11 had an UMN lesion (six complete, five incomplete), eight a LMN (seven complete, one incomplete) and three a mixed lesion.

Treatment:
Eight tablets of apomorphine sublingual (SL) 3 mg, as a primary or secondary treatment for erectile dysfunction (ED)

Outcome Measures:
International Index of Erectile Function questionnaire, patient diaries. A neurophysiological evaluation included somatosensory evoked potentials of the pudendal nerve, palmar and plantar sympathetic skin responses and bulbocavernous reflex recordings.

  1. There were no significant correlations for electrophysiological or urodynamic findings and treatment success.
  2. Seven patients had some response and reported that the drug helped them to obtain an erection, but only two reported erections sufficient for intercourse and would agree to continue apomorphine SL as their standard treatment; all the others reported being disappointed. Nine patients reported side-effects.
