6. PLAN: Women, 18 years old or greater, who are having their ovaries removed will be enrolled in the protocol. 110 total specimens will be obtained. At our institution approximately 200 patients per year have ovaries removed. All patients who have had gynecologic tissue removed for benign (non cancerous) or malignant (cancerous) indications will meet inclusion criteria. Patients who have a malignancy that is not a primary gynecologic malignancy will be excluded from the study. Each patient's intratumoral vascularity will be assessed by Doppler ultrasound and systemic blood pressure measured preoperatively.
