This protocol is designed to allow inpatient and outpatient evaluation of women with a variety of reproductive and endocrine-related disorders for purposes of research and physician education in our accredited reproductive endocrine training program. The evaluations may include ultrasound examinations and the collection of blood, saliva, and/or urine samples. In some cases, laboratory or radiologic studies will be performed to confirm the diagnosis or to aid in the management of the patient, as would be done in current gynecologic practice. In some cases, the patient will receive medical or surgical treatment for their disorder. The purpose of these evaluations or treatments will be to support our clinical training and/or research mission. In particular, this protocol is intended to provide a mechanism for reproductive endocrine fellows and staff to evaluate women with medical conditions of interest for fellow teaching and clinical training.
