2026年10月6日，《人类生殖》杂志发表了一项关于澳大利亚和新西兰女性计划性卵子冷冻的长期随访研究 1。该研究追踪了2009年至2023年间进行计划性卵子冷冻的20,209名女性 1。数据显示，在至少随访10年的群体中，约27.9%的女性返回医院解冻卵子用于妊娠；而在随访5年的群体中，这一比例为22.1% 1。在使用冷冻卵子尝试妊娠的女性中，有33.9%成功娩出婴儿 1。
针对公众关注的冻卵效果，深圳市妇幼保健院专家刘大艳指出，冻卵时的年龄和冷冻成熟卵子的数量对最终生育成功的概率具有重要影响 1。通常情况下，女性年龄越小，卵子质量越好 1。刘大艳强调，目前不存在一个能保证未来生育成功的统一冻卵数量标准 1。
A long-term follow-up study published on October 6, 2026, in the journal Human Reproduction has shed light on the actual usage rates of planned egg freezing among women in Australia and New Zealand 1. The research, titled "Fifteen-year Follow-up of Elective Oocyte Cryopreservation: Survival and Success Rates in Australia and New Zealand," analyzed data from a cohort of 20,209 women who underwent elective oocyte cryopreservation between 2009 and 2023 1. Among the subset of participants followed for at least ten years, only 27.9% returned to thaw their eggs for pregnancy attempts, while the return rate was lower at 22.1% for those with five years of follow-up 1. Of the women who did attempt pregnancy using their frozen eggs, 33.9% successfully delivered an infant 1.
Liu Dayan, an expert from the Shenzhen Maternity and Child Healthcare Hospital, emphasized that age at the time of freezing and the number of mature eggs stored are critical factors influencing future reproductive success 1. She noted that younger women typically possess higher egg quality, but there is no universal standard for the number of eggs required to guarantee a successful outcome in the future 1.
