Prognosis

  • Depends upon primary reason for surgery.
  • Guarded for behavioral reasons - although normal oestrus cycles are prevented, this may not alleviate the abnormal behavior.
  • Guarded for ovarian granulosa theca cell tumors   Ovary: neoplasia - granulosa / theca cell  .
  • Unilateral resection: mares return to estrus in mean of 8.5 months (usually must go through the winter cycle).
  • Once the normal cycle has started, fertility appears to be unaffected.
