Sexual impotence: a double-blind study of LHRH nasal spray versus placebo

Abstract

A double-blind study comparing application of 1.0 mg LHRH nasal spray per day against a placebo was performed in a group of 20 sexually impotent patients in whom no clinical endocrinological pathology was evident. After a 2-week placebo-spray period, LHRH was given for 4 weeks. A 2-week placebo-spray period followed. A better therapeutic effect was seen in the LHRH as opposed to the placebo group (p = 0.024) 4-6 weeks after cessation of LHRH medication. After 4 weeks of LHRH medication there were no changes in basal LH/FSH levels or in the LH response after administration of 25 mug LHRH. The FSH response was, however, significantly lower.
