NOVELTY - The device (10) has a pair of sensors e.g. strain gauges (70, 80), mounted proximate to an annular rigid ring (20) inserted into a body cavity e.g. vagina, and interconnected to a battery and a memory e.g. electrically erasable programmable ROM. The sensor monitors physiological parameter, generates an output indicative of the parameter, and stores the output in the memory. A bio-inert coating i.e. medical grade silicone, covers a portion of the battery, the memory and the sensors. An electrical circuitry/control module (40) e.g. microprocessor, controls the operation of the sensors.    USE - Self-contained intra-vaginal monitoring device for monitoring, diagnosing, and treating hypogonadism in a female patient, and for delivering therapeutic agents e.g. local anesthesia before endocervix biopsies, antifungal and anti-infective, during hormonal therapy and treatment of vaginal and cervical dysplasia and cancer, to the patient.    ADVANTAGE - The device enables periodic measurements of multiple physiological parameters, storage of the physiological parameters and subsequent download or transfer for processing or other evaluation of the physiological parameters. The bio-inert coating isolates the battery, the memory device and the sensor from bodily fluids, thus positioning the device within a body cavity for an extended period of time e.g. 6-48 hours or more, to obtain multiple parameter measurements of a sample group. The device can be sterilized and reused on a common patient or different patients. The device includes a valve that allows controlled delivery of therapeutic agents to the cervix and/or vagina.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a method for generating diagnostic markers associated with hypogonadism in a female patient    (2) a method for monitoring hypogonadism in a female patient.
