title: Ovarian remnant syndrome: study in laboratory rats.
abstract: OBJECTIVE
  This study was designed to answer two questions: (1) will devascularized ovarian rat tissue reimplant on intact or denuded peritoneal surfaces, and (2) will any revascularized tissue become functional, as evidenced by follicle formation and vaginal cornification?
  
  
  METHODS
  A total of 110 young female Sprague-Dawley rats were divided into four study groups and a control group. Bilateral oophorectomy was performed on the rats in the first three study groups. In these groups the ovaries were sutured to the left peritoneal surfaces, where the devascularized tissue might become revascularized. The vascularized ovary was sutured to the right denuded peritoneal surface in the rats in group 4, and an oophorectomy was performed on the rats in the control group. The study animals were killed and evaluated at 3, 6, or 9 weeks postoperatively.
  
  
  RESULTS
  Seventy-five percent of the devascularized ovarian tissue revascularized. Forty-three percent of the viable ovarian tissue demonstrated follicular growth that increased with time to death. Thirty-seven percent of the rats showed the effects of estrogen on the vaginal epithelium.
  
  
  CONCLUSIONS
  This study indicates that devascularized ovarian tissue may reimplant on intact or abraded peritoneal surfaces, where in time it may resume functioning. These findings suggest that great care must be taken when using the laparoscope to collect ovarian specimens.
