Medical screening will occur in conjunction with the initial entry interview. All patients must have had a gynecologic exam within the past year and if not, study personnel will provide a referral for an exam. The investigators will review the patient's medical history. Laboratory tests will include thyroid function tests (TFTs), liver function tests (LFTs), renal panel, pregnancy tests, and complete blood count (CBC). Subjects will also complete the Greene Climacteric Scale, which is used to quantify the severity of perimenopausal symptoms.
