Male orgasmic disorder is commonly encountered among patients treated
with thioridazine. This side effect interferes significantly with sexu
al satisfaction. In this pilot study, eight male schizophrenic patient
s who complained of orgasmic disorder, compatible with probable retrog
rade ejaculation during thioridazine treatment, were given concomitant
low-dose imipramine (25-50 mg at bedtime). Four of the eight reported
complete resumption of their previous ejaculatory function, and in on
e patient there was a partial, but substantial, improvement. Three pat
ients noted no change. It appears that imipramine might be beneficial
for some patients with thioridazine-induced male orgasmic disorder.
