What this trial studies

This observational study assesses the effects of inflammatory bowel diseases, specifically Crohn's disease and ulcerative colitis, on fertility and pregnancy outcomes in female patients. It involves a cross-sectional, international, multicenter approach, where data will be collected from female patients who underwent surgery before the age of 36 between 2000 and 2020. Participants will complete a questionnaire regarding their fertility and pregnancy experiences, while demographic and treatment data will be retrospectively gathered by local investigators. The study aims to identify factors associated with infertility and complications during pregnancy and delivery.

Who should consider this trial

Good fit: Ideal candidates are female patients diagnosed with Crohn's disease or ulcerative colitis who underwent surgery before the age of 36.

Not a fit: Patients younger than 18 years old at follow-up or those without a definitive diagnosis or surgical procedures performed may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the reproductive health of women with inflammatory bowel diseases, leading to improved care and support.

How similar studies have performed: While similar studies have explored the impact of inflammatory bowel diseases on fertility, this specific approach focusing on surgical patients is relatively novel.
