Official title
Is Decreased Ovarian Reserve Related to an Increased Number of Previous Early Miscarriages? A Prospective Observational Study
Overview
This study aims to explore the potential correlation between decreased ovarian reserve and previous history of early miscarriage.
Detailed description
By investigating the prevalence of low ovarian reserve (LOR) in populations with specific reproductive histories (such as recurrent pregnancy loss, G0, and ectopic pregnancy), as well as the aneuploidy rates of embryos produced with Preimplantation Genetic Testing for Aneuploidies (PGT-A), Investigators can better understand how LOR impacts fertility outcomes in these populations. This information can be used to inform clinical decision-making, such as whether participants with LOR should consider alternative or whether they would benefit from additional interventions to improve ovarian function.
Ultimately, by improving our understanding of how LOR impacts fertility outcomes in specific populations, Investigators can help to improve the overall success rates of infertility treatment, reduce anxiety, and distress, and help participants achieve goals of becoming parents.
Interventions
- Diagnostic test Transvaginal ultrasound
Transvaginal ultrasound for antral follicle count (AFC) performed on the day of first consultation - Diagnostic test Blood test AMH
Measurement of AMH performed on the day of first consultation
Primary outcome measures
- AMH [Time frame: 1 day]
- AFC [Time frame: 1 day]
