title: Laparoscopic ovarian cystectomy of endometriomas does not affect the ovarian response to gonadotropin stimulation.
abstract: OBJECTIVE
  To evaluate the ovarian response cycles of IVF-ET in patients who previously underwent laparoscopic cystectomy for endometriomas.
  
  
  METHODS
  Retrospective study with prospective selection of participants and controls.
  
  
  METHODS
  Instituto de Ginecología y Fertilidad Buenos Aires, Argentina.
  
  
  METHODS
  Thirty-nine patients underwent an operation for ovarian endometriomas by atraumatic removal of the pseudocapsule with minimal bipolar cauterization of small bleeders and an IVF-ET cycle (group A) and 39 control patients of similar age underwent an IVF-ET cycle for tubal factor infertility (group B).
  
  
  METHODS
  Laparoscopic endometrioma cystectomy, IVF-ET cycle.
  
  
  METHODS
  E(2) levels, number of gonadotropin ampoules, follicles, oocytes retrieved, number and quality of embryos transferred, and clinical pregnancy rate.
  
  
  RESULTS
  There were no differences in all the parameters studied (E(2) levels, number of follicles, oocytes retrieved, number and quality of embryos transferred, and clinical pregnancy rate) except for the number of gonadotropin ampoules needed for ovarian hyperstimulation, which was significantly higher in group A than in group B.
  
  
  CONCLUSIONS
  Our results indicate that laparoscopic cystectomy for endometriomas is an appropriate treatment since it did not negatively affect the ovarian response for IVF-ET.
