Objective:
To study the impact of surgically verified endometriosis and serum and peritoneal fluid antiendometrial antibodies (AEA) on pregnancy outcomes in gamete intrafallopian transfer (GIFT), zygote intrafallopian transfer (ZIFT) and in vitro fertilization (IVF) patients using assisted reproductive technologies (ART).
Study Design:
Surgical evaluation of endometriosis and collection of serum and peritoneal fluid was performed at the time of laparoscopy. For patients who did not undergo laparoscopy, only serum samples were obtained. Sera and peritoneal fluid were tested by indirect immunofluorescence for AEA.
Results:
There was no correlation between surgically verified endometriosis, serum or peritoneal fluid AEA and clinical pregnancy in patients undergoing ART. There was no significant difference in surgically verified endometriosis in patients who delivered and those who miscarried (p < 0.0594), whereas serum (p < 0.0223) and peritoneal fluid (p < 0.0032) AEA showed differences. In the total group of 352 ART patients, positive serum AEA was statistically significant in those who miscarried vs. those who delivered (p < 0.0000).
Conclusion:
Endometriosis does not significantly impair the pregnancy potential of ART patients, but it may be associated with miscarriage. The presence of serum and peritoneal fluid AEA correlate better with miscarriage than surgically verified endometriosis.
