title: Prolonged elevation of luteinizing hormone (LH) after intranasal administration of an analog of LH-releasing hormone.
abstract: [D-Leu-6,desGly-NH2-10]-LH-RH-ethylamide, an analog of luteinizing hormone-releasing hormone (LH-RH), was administered by intranasal spray or tube to 18 healthy men. A significant release of LH occurred within 15 minutes and was sustained for as long as 12 hours in what appeared to be a diphasic response. Both the spray and rhinyl tube were shown to be effective methods for releasing LH by intranasal administration of the LH-RH analog.
