Subjects will undergo an initial visit which will include a blood draw, ultrasound, and any additional tests or exams that are medically indicated for the subject's diagnosis in preparation for surgery. Subjects will then undergo an oophorectomy surgery (removal of one or both ovaries). Following removal, subject's ovarian tissue will be cryopreserved (frozen) and stored for possible future use. We also plan to collect subjects medical history information to enter into a research database. Subjects will be followed until they decide to use their tissue for fertility purposes.
