What this trial studies

This research compares the effectiveness of 2D and 3D ultrasonography in diagnosing ovulation and anovulation in healthy women. Thirty participants will receive indomethacin to induce anovulation, followed by daily ultrasound scans and hormonal tests to monitor changes. A second group of participants from a previous study will serve as a control to evaluate the differences in ultrasound features between ovulatory and anovulatory conditions. The goal is to determine if 3D ultrasonography offers improved assessment for infertility treatments.

Who should consider this trial

Good fit: Ideal candidates are healthy biological females with regular menstrual cycles.

Not a fit: Patients with a history of infertility or reproductive health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of ovulation assessments, leading to better infertility treatment outcomes.

How similar studies have performed: Previous studies have explored similar methodologies, but this specific comparison of 2D and 3D ultrasound in ovulation detection is relatively novel.
