The efficacy of non-assisted reproductive technology treatment might be limited in infertile patients with advanced endometriosis in their 30s.

Abstract

To determine the efficacious treatment for infertile couples, we assessed the impact of infertility factors including endometriosis on assisted reproductive technology (ART) and non-ART treatment, and the effect of age in infertility treatment outcomes was also investigated. The medical records of 1864 females, infertile patients from January 2000 to December 2015 at our hospital, were retrospectively reviewed under the approval of the Institutional Review Board. We extracted 10 representative factors and calculated the cumulative live birth rate (CLBR) in these patients. Multivariate analysis of ART and non-ART treatment was performed to assess the impact of infertility factors, and the age-related decline in cumulative live birth rate was calculated by creating eight age-stratified subgroups. In total, 21.9% and 49.4% of the patients conceived after being treated with non-ART and ART, respectively. Multivariate analysis revealed that age > 35, advanced endometriosis defined by the revised American Society for Reproductive Medicine classification system stages III to IV, and the past history or current presence of uterine fibroid had significantly negative impact on the outcome of non-ART. Age stratification revealed that advanced endometriosis adversely affected the outcome of non-ART, especially for patients in their 30s. Assisted reproductive technology treatment for patients with advanced endometriosis was shown to be efficacious because the negative impact had been diminished. Considering that non-ART treatment had limited role in patients with advanced endometriosis, prompt initiation of ART in these patients aged as young as 30 years can be recommended to achieve conception.
