Association Between Inflammatory Bowel Disease in Women and the Fertility Marker Anti-Müllerian Hormone.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundInflammatory Bowel Disease (IBD) is an immune-mediated disorder characterized by chronic intestinal inflammation. IBD, along with its associated treatments, may have systemic effects including potential implications for female fertility. Anti-Müllerian hormone (AMH) levels are commonly used as a biomarker of ovarian reserve and fertility potential. However, the impact of IBD and its therapies on AMH levels remains unclear. This study aims to evaluate the association between IBD, AMH levels, and fertility. MATERIALS AND
methodsThis retrospective study analyzed electronic medical records from a multicenter academic institution from January 2017 to September 2024. Female patients with recorded AMH levels and a diagnosis of IBD were identified and compared to a control group without an IBD diagnosis. Baseline characteristics were compared between the two groups. Fisher's exact test was used for statistical analysis.
resultsA total of 146 patients were included in the study, with 67 patients diagnosed with IBD and 79 control patients. Among patients with IBD, 7.5% (5/67) exhibited low AMH levels, whereas 12.7% (10/79) of non-IBD patients had low AMH levels (p=0.41). In multivariable logistic regression adjusting for age, ethnicity, body mass index, nicotine use, and hormonal therapy, IBD was not significantly associated with low AMH levels (OR 0.67, 95% CI 0.21-2.18, p=0.505). In age-stratified analyses using Fisher's exact test, IBD status was not significantly associated with low AMH levels in women under 35 (p=0.055) or those aged 35 and older (p=0.733). Additionally, we did not identify a significant association between low AMH levels and IBD subtype; p=1.00. No significant association was observed between low AMH levels and disease activity.
conclusionOur study did not identify a statistically significant association between IBD and low AMH levels. These findings should be interpreted cautiously due to the modest sample size, differences in hormonal therapy use, and a cohort in which most patients had mild or inactive disease. Future studies with larger sample sizes evaluating the impact of disease activity and treatment exposure on fertility outcomes in IBD patients are needed to provide additional guidance on early referral of these patients for fertility evaluation.
