Reproductive outcome and gynecologic comorbidities in women with endometriosis in a non-IVF setting: a retrospective study.

Background Endometriosis-related infertility is a disease associated with significant morbidity and distress to the couple and requires timely, multidisciplinary, and often high-cost care involving assisted reproductive technologies (ART). Many health care systems in the Middle East do not provide coverage for ART. This study aims to describe the reproductive outcome in a form of a clinical pregnancy rate in women with endometriosis-related infertility in a health care system that does not provide coverage for ART. Results This is a retrospective observational cohort study on women who attended the gynecology clinic in a tertiary center in Oman with the diagnosis of endometriosis from January 2011 to December 2019. Women of reproductive age seeking pregnancy were included in the analysis. Out of total women with endometriosis, (144/262) 55.0% were included in the analysis with a mean age of 31.10 ± 5.73 years. The mean duration of follow-up was 30.18 months and 43/144 (29.9%) of our patients had a follow-up > 60 months. Based on surgical staging, 11.8% had mild disease, 70.1% had moderate to severe disease and 18.1% were not operated. After a thorough assessment, (30.2%) were advised to seek in vitro fertilization (IVF) as a primary treatment for infertility but 23.08% declined the advice. Of the 144, 24.3% achieved a clinical pregnancy. (16/144), 11% conceived spontaneously. 11/144) 7.6% conceived with ovulation induction ± intrauterine insemination (OI ± IUI) and the rest conceived with a self-sponsored IVF. The overall clinical pregnancy rate was not statistically different between those who had surgery and those did not have surgery (P value 0.474). The pregnancy rate based on the management plan were; surgery + IVF (7/25, 28.0%), surgery + OI/IUI (10/47, 21.3%), surgery alone (9/33, 27.3%). The pregnancy rate was not statistically different between the groups (P value 0.782). In addition to endometriosis, a significant proportion (63/144, 43.8%) of these women have a coexisting gynecologic morbidity including 2.1% non-endometrioma ovarian cyst, 13.9% myomas, 4.2% adenomyosis, 8.3% Mullerian anomalies, 2.1% polycystic ovary syndrome, 6.3% pelvic inflammatory disease or tubo-ovarian abscess and 1.4% biopsyproven endometritis. Conclusion The reproductive outcome of patients with endometriosis in this study population was generally poorer than what is reported in the literature with an overall pregnancy rate of 24.3% and a spontaneous pregnancy rate of 11%. Several causes can be noted for such an outcome, including advanced disease stage, coexisting gynecologic morbidities, and poor access to advance fertility management. [ABSTRACT FROM AUTHOR]
