Decision Aid for Elective Egg Freezing

The goal of this clinical trial is to evaluate whether a culturally tailored decision aid can improve decision-making and clinical outcomes for Taiwanese women considering elective egg freezing. The main questions it aims to answer are: Does the decision aid improve women's knowledge about elective egg freezing and help clarify their personal values? Does the decision aid reduce decision regret and psychological distress after making a decision about egg freezing? Researchers will compare women who use the decision aid with those who receive standard counseling to see if the tool improves knowledge, reduces distress and regret, and leads to better clinical outcomes (such as completing egg freezing or achieving a higher number of frozen oocytes). Participants will: * Complete questionnaires assessing their baseline knowledge, attitudes, and values regarding egg freezing * Receive either the decision aid or standard counseling * Complete follow-up questionnaires to assess knowledge, distress, and decision regret * Have their clinical outcomes recorded, including whether they undergo egg freezing and the number of oocytes retrieved and frozen

Inclusion Criteria: * Women aged 20 years or older. * Currently considering elective egg freezing (EEF). * Able to communicate and read Chinese fluently. * Have access to the internet and a mobile device (smartphone, tablet, or computer) to complete online questionnaires. Exclusion Criteria: * Individuals who have previously completed oocyte cryopreservation. * Women undergoing fertility preservation due to malignancy (i.e., breast cancer). * Postmenopausal women.
