A high frequency of sexual dysfunction occurs in treated and untreated pati
ents with schizophrenia. Unfortunately, no effective therapy for this probl
em is currently available. We present a case of a 26-year-old patient with
paranoid schizophrenia, who suffered from lack of desire and erection, and
was successfully treated with sildenafil citrate (Viagra). This case illust
rates the complex character of sexual dysfunction in male schizophrenic pat
ients. (C) 1999 Editions scientifiques et medicales Elsevier SAS.
