  1. No statistically significant differences were found between different patient diagnosis (SRS, adnexal mass, and adenocarcinoma) at each step (IVM, oocyte activation and development).
  2. a Age of patient at the time of oocyte collection.
  3. b All MII oocytes were vitrified after IVM.
  4. c One embryo reached the blastocyst stage.
  5. d Fisher’s exact test.
  6. IVM, in vitro maturation; MII, metaphase II.
