title: A laparoscopic technique for obtaining ovarian cortical biopsy specimens for fertility conservation in patients with cancer.
abstract: OBJECTIVE
  To evaluate the efficacy of a newly designed round biopter as a practical and safe method for collecting ovarian tissue for cryopreservation in young women with cancer before chemotherapy.
  
  
  METHODS
  Prospective study of young women volunteering for research (Leeds, United Kingdom) and patients with cancer (Jerusalem, Israel and Leeds, United Kingdom) undergoing laparoscopic ovarian cortical tissue biopsy and cryopreservation before administration of high-dose radiochemotherapy.
  
  
  METHODS
  Two university-based tertiary referral centers of oncology and gynecology (Hadassah Medical Center, Israel; Leeds General Infirmary, United Kingdom).
  
  
  METHODS
  Twenty female volunteers undergoing routine laparoscopic gynecologic procedures (age, 25-34 years) and 20 young women (age, 11-30 years) with advanced cancer requiring potentially sterilizing radiochemotherapy.
  
  
  METHODS
  Cortical ovarian tissue biopsies performed under laparoscopy with use of the round biopter.
  
  
  RESULTS
  The laparoscopic sampling procedure was uncomplicated in all cases. In treated patients, five to six samples were obtained (5 mm in diameter; 2-3 mm in depth) using the round biopter, and radiochemotherapy was administered without delay. In volunteers, no adhesions were noted at repeat laparoscopy (9 patients). All biopsy specimens were cryopreserved, and histologic examination confirmed the presence of many primordial follicles.
  
  
  CONCLUSIONS
  Laparoscopic ovarian biopsy performed with the round biopter is a safe and efficient method for collecting ovarian tissue for cryopreservation in patients with cancer.
