Sponsored by ART Fertility Clinics LLC · Observational
This study aims to explore the potential correlation between decreased ovarian reserve and previous history of early miscarriage.
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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
1. All participants with at least 1 previous pregnancy, who are assessed in one of our clinics (ART Fertility Clinics Abu Dhabi, Al Ain, Dubai)
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Participants will not undergo any additional intervention compared to normal clinical assessment and routine testing of the ovarian reserve, which includes AMH and AFC. Investigators will follow standard stimulation protocols and medications.
