Reproductive Outcomes and Overall Prognosis of Women with Asherman's Syndrome Undergoing IVF.

STUDY

OBJECTIVE

To evaluate the impact of Asherman syndrome (AS) following hysteroscopic adhesiolysis on reproductive outcomes and the time to achieve pregnancy in women with infertility undergoing in vitro fertilization (IVF) treatment.

DESIGN

Case-control study.

SETTING

Tertiary university-affiliated medical center.

PATIENTS: Fifty-one infertile women who were treated for AS and underwent IVF (study group) matched for age and etiology of infertility with non-AS controls at a 1:1 ratio.

INTERVENTIONS: Medical records search, chart review, and phone survey were used to assess reproductive outcomes.

MEASUREMENTS AND MAIN

RESULTS

A multivariate logistic regression analyses was used to assess live birth, accounting for patient age at stimulation cycle start, parity, number of embryos transferred, and endometrial thickness. A survival analysis was performed to assess the times that had lapsed from interventions to conception. The study group of 51 women included 38 (74.5%) with moderate to severe disease. The mean number of embryo transfers per woman was similar for the study and control groups (4.9 ± 4.6 vs 6.22 ± 4.3, respectively, p = .78). The controls had a significantly higher mean endometrial thickness before embryo transfer (8.7 ± 1.8 mm vs 6.95 ± 1.7 mm, p = .001). The overall time to achieve live birth was significantly longer in women with AS (p = .022). In a logistic regression analysis, the presence of moderate to severe AS was shown to be an independent factor for achieving a live birth (adjusted odds ratio 0.174, 95% confidence interval [CI], 0.032-0.955, p = .004). Women with AS who had live births had a significantly thicker mean endometrial thickness (8.2 ± 1.4 mm vs 6.9 ± 1.2, p = .001).

CONCLUSION

Moderate and severe AS has a detrimental effect on reproductive performance in infertile women. Endometrial thickness is an important predictor for live births among women with AS who undergo IVF.
