Abstract

In the last few decades, there have been tremendous developments of assisted reproductive technologies, but the outcome of in vitro fertilization is highly dependent on the age of the oocyte. The introduction of vitrification offers a possibility to freeze eggs proactively in younger years and use them at later ages, also called social egg freezing. Knowledge about age-related fertility decline is insufficient among many women, and there is an overoptimistic trust that in vitro fertilization can overcome this. The awareness of proactive egg freezing is limited, both among doctors and in the general population. This review aims at increasing the knowledge about proactive egg freezing and offers a means to advise women correctly. It deals with national guidelines, the best age and optimal number of eggs to freeze, and the chance to succeed. Creating more public awareness about age-linked fertility decline and elective egg freezing may help women reproduce at their own pace – to take control of their fertility.

摘要

在过去的几十年中，辅助生殖技术取得了巨大的发展，但是体外受精的结果高度依赖于卵母细胞的年龄。玻璃化的引入提供了在年轻时主动冷冻卵子并在以后使用它们的可能性，这也被称为社会卵子冷冻。在许多女性中，与年龄相关的生育能力下降的知识不足，而且人们对体外培养过于乐观施肥可以克服这一点。在医生和普通人群中，主动冷冻鸡蛋的意识是有限的。这篇综述旨在增加有关主动冷冻卵子的知识，并为正确建议女性提供一种手段。它涉及国家准则，要冷冻的最佳年龄和最佳卵数以及成功的机会。在与年龄有关的生育能力下降和选择性卵子冷冻方面建立更多的公众意识，可以帮助妇女按照自己的步调繁殖-控制生育力。
