title: EFFECT OF PELVIC ENDOMETRIOSIS, ENDOMETRIOMAS AND RECURRENT ENDOMETRIOMAS ON IVF-ET/ICSI OUTCOMES.
abstract: BACKGROUND
  Endometriosis, the most common gynecological disorder, is a challenging disease observed in 20% - 40% of subfertile women.
  
  
  METHODS
  380 women were divided into four groups. Group A consisted of 176 women with pelvic endometriosis. Group B consisted of 125 women who had previously undergone a laparoscopic endometrioma cystectomy. Group C consisted of 38 women with recurrent endometriomas without aspiration before IVF-ET/ICSI. Group D consisted of 41 women with recurrent endometriomas undergone aspiration before IVF-ET/ICSI.
  
  
  RESULTS
  Baseline FSH level (8.61 ± 3.42 mIU/mL) and total dose of Gn (2337.15 ± 853.00 IU) in Group A were the lowest (p < 0.05). The number of retrieved oocytes in Group B (7.98 ± 5.05) was significantly fewer than those in Group A and D (p < 0.05). The numbers of MII oocytes in Groups A, C and D were significantly larger than that in Group B. The number of retrieved oocytes, high-quality embryos, implantation and pregnancy rates were similar in Groups C and D.
  
  
  CONCLUSIONS
  Pelvic endometriosis had a less adverse effect on ovarian reserve than endometrioma. No advantage was found in transvaginal aspiration for recurrent endometriomas before IVF-ET/ICSI.
