Ectopic ovary: Abnormally located ovary
Inguinal ovarian hernia (95%): Presents as labial mass
Intraabdominal ectopia: Incidental or iatrogenic
Nonstandard ovarian location common & usually incidental (due to long ovarian ligaments)
Nonpelvic location sometimes seen after numerous or complex abdominopelvic surgeries
