What this trial studies

This observational study investigates the correlation between decreased ovarian reserve (LOR) and a history of early miscarriages in women. By assessing the prevalence of LOR in populations with specific reproductive histories, including recurrent pregnancy loss and ectopic pregnancies, the study aims to understand how LOR affects fertility outcomes. Participants will undergo transvaginal ultrasound and blood tests to measure AMH levels, which will help inform clinical decisions regarding fertility treatments. The findings could lead to improved success rates in infertility treatments and reduced anxiety for participants seeking to become parents.

Why it matters

Potential benefit: If successful, this study could enhance understanding of fertility issues and improve treatment strategies for women with decreased ovarian reserve.

How similar studies have gone: While the correlation between ovarian reserve and miscarriage has been explored, this specific approach focusing on reproductive history and PGT-A outcomes is relatively novel.
