title: Retrieval of immature oocytes after chemotherapy for Hodgkin's disease and prolonged ovarian down-regulation with gonadotropin-releasing hormone agonist.
abstract: OBJECTIVE
  To describe isolation and in vitro maturation of primary oocytes from the ovarian cortex in the presence of hypothalamic pituitary down-regulation.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Tertiary care university-affiliated hospital.
  
  
  METHODS
  An 18-year-old patient was given treatment with the ABVD (Adriamycin, bleomycin, vinblastine, and dacarbazine) protocol for Hodgkin's disease. She underwent ovarian tissue cryopreservation while being cotreated with GnRH agonist because of disease relapse.
  
  
  METHODS
  Laparoscopic oophorectomy, ovarian tissue cryopreservation, and in vitro maturation of primary oocytes.
  
  
  METHODS
  Maturation of primary oocytes isolated from the medium used for preparation of ovarian tissue.
  
  
  RESULTS
  Twenty-one immature germinal vesicle-stage oocytes were isolated from the medium of dissection. All were incubated in in vitro maturation medium, and five were maturated and frozen.
  
  
  CONCLUSIONS
  The fact that germinal vesicle-stage oocytes were present in our patient's medium despite hormonal down-regulation demonstrates that GnRH agonist does not completely inhibit antral follicle development.
