title: Factors affecting postoperative pregnancy rate after endoscopic management of large endometriomata.
abstract: OBJECTIVE
  To identify factors influencing postoperative pregnancy rate in women with extensive endometriosis and large endometriomata as the only identified cause of infertility that were treated by laparoscopy.
  
  
  METHODS
  Sixty-four infertile patients with endometriomata (> or = 3 cm) and no other apparent cause of infertility. The latter were removed by operative laparoscopy. Life table calculations, the Student's t-test and the chi2 test were used where appropriate.
  
  
  RESULTS
  Thirty-four patients (53%) became pregnant during the 2-year follow-up period. A significantly increased pregnancy rate was found for the first year compared to the second (76 vs. 24%). The existence of adhesions affected adversely the outcome of the operation only as far as early achievement of pregnancy is considered. The number and size of endometriomata and the existence of peritoneal implants have not been found to affect pregnancy rates. The severity of the disease did not affect pregnancy rate, but in the cases with moderate disease most of the pregnancies were achieved during the first postoperative year. The duration of infertility was significantly associated only at the 10% level with decreased pregnancy rates.
  
  
  CONCLUSIONS
  Extensive endometriosis with large endometriomata can be safely and effectively treated with laparoscopy using the traditional laparoscopic tools providing the infertile patient with a high chance to conceive in a relatively short period of time postoperatively.
