Abstract: A method for diagnosing and treating urogenital disorders associated with atrophic vaginitis in symptomatic women having vaginal pH of 4.5 or above allows documentation of symptoms, justifies estrogen use and can be used to determine the duration of treatment. The method includes measuring and recording vaginal pH, and intravaginally administering a dose of estrogen using a prefilled applicator. The applicator comprises an elongated curved tubular reservoir for containing a gel, cream or ointment, and a plunger, sealingly seatable within the reservoir and operable to displace estrogen gel, cream or ointment therefrom. The outside diameter of the reservoir ranges from 0.25 to 0.375 inches.
