The present invention provides methods and compositions for inducing penile erections, sufficient for vaginal penetration, in a human male suffering from impotence. When the impotence is substantially only neurogenic, psycogenic or neurogenic and psychogenic, a method of the invention comprises (A) administering to the male by intracavernosal injection peptide N-terminal histidine C-terminal methionineamide and (B) sexually stimulating the male. When the impotence is caused by severe atherosclerosis, a method of the invention comprises (A) administering to the male by intracavernosal injection an amount of a physiologically acceptable composition comprising (1) a neuropeptide selected from the group consisting of human vasoactive intestinal peptide and peptide N-terminal histidine C-terminal methionineamide and (2) an alpha-adrenergic blocker, such as phentolamine or prazosin, and (B) sexually stimulating the male. The invention also entails a physiologically acceptable composition suitable for use in inducing, upon administration by intracavernosal injection, an erection, sufficient for vaginal penetration, in a human male suffering from impotence, which is caused by severe atherosclerosis, which composition comprises (1) a neuropeptide selected from the group consisting of vasoactive intestinal peptide and peptide N-terminal histidine C-terminal methionineamide and (2) an alpha-adrenergic blocker, such as phentolamine or prazosin. |
