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.\n\nUltimately, 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.","All participants who visit ART Fertility clinics in Abu Dhabi, Al Ain and Dubai for first consultation",[23,29,32,36],{"label":24,"type":16,"description":25,"interventionNames":26},"AMH \u003C1.3, at least 1 pregnancy or at least 1 miscarriage","Participants will not undergo any additional intervention compared to normal clinical assessment and routine testing of the ovarian reserve, which includes AMH and AFC.
