Awareness and Decisions Regarding Elective Oocyte Cryopreservation (EOC) in Greece: A Cross-Sectional Study on Generation Z

Background: Oocyte cryopreservation has emerged as a viable fertility preservation method, gaining popularity among women delaying motherhood for non-medical reasons. This study examines the awareness, perceptions, and social factors influencing young women’s decisions regarding elective oocyte cryopreservation (EOC), intending to identify key demographic and psychosocial determinants. Methods: A cross-sectional study was conducted using an online survey distributed via digital platforms between November 2024 and February 2025. A structured questionnaire comprising 31 multiple-choice questions assessed participants’ sociodemographic characteristics, reproductive health history, lifestyle factors, and perceptions of fertility and EOC. Statistical analyses included Chi-square tests, t-tests, and binary logistic regression to identify factors associated with willingness to undergo EOC. Results: A total of 390 women (mean age 22.57 ± 1.41 years) participated. Awareness of oocyte cryopreservation was remarkably high (93.1%). Significant predictors for the intention to undergo EOC included higher educational attainment (Master’s level) (OR = 4.27, 95% CI: 1.10–16.48) and living in a student dormitory (OR = 15.39, 95% CI: 4.86–48.71). Conversely, living with a partner showed a non-significant downward trend in interest (OR = 0.07, 95% CI: 0.01–1.43). Psychological factors, specifically anxiety about future fertility (OR = 0.23, 95% CI: 0.08–0.62 for moderate vs. high anxiety) and a strong desire for future parenthood (OR = 21.75, 95% CI: 1.45–32.99), also emerged as primary drivers of women’s reproductive decisions. Conclusions: Despite high awareness, the willingness to undergo elective oocyte cryopreservation remains limited. Targeted fertility education and supportive policies are needed to address misconceptions, financial barriers, and psychological concerns influencing reproductive decision-making. Further research should explore longitudinal trends in women’s attitudes toward EOC.
