Research question

What do Danish and Israeli students of both sexes know about age in relation to fertility and gamete preservation, and what are their concerns and intentions for the future in this regard?

Design

A cross-sectional comparative study of male and female Danish and Israeli students was conducted between November 2018 and April 2019. A total of 1010 students, 508 from Denmark and 502 from Israel, completed questionnaires assessing knowledge, perceptions and intentions regarding gamete preservation.

Results

More than 70% of both genders in Israel thought that women start experiencing fertility decline at age 35 and up. A total of 60% of Danish women and 51% of Danish men chose 29–34 as the time where fertility decline starts. Some 95% of Danish students chose 20–29 as the best age for egg freezing, while the corresponding number in Israel was 85%, regardless of gender. In total, 51% of Israeli women said they are extremely or very worried about future infertility, compared with 31% of Danish women, 26% of Israeli men and 12% of Danish men. Regarding preservation intentions, no gender differences were found. Some 3% of Israeli students said they would consider gamete preservation, as compared with 14% of Danish students.

Conclusions

These findings suggest a widespread worry among Danish and Israeli women about their future fertility. Danish students report more awareness of age-related fertility decline. Unique to this study is the inclusion of male students. The preliminary findings reveal that men are less worried about their reproductive future.

配子保存：以色列和丹麦学生关于卵子和精子冷冻的知识、担忧和意图。

研究问题

丹麦和以色列的男女学生对生育和配子保存的年龄了解多少，他们在这方面的担忧和未来打算是什么？

设计

2018 年 11 月至 2019 年 4 月期间，对丹麦和以色列男女学生进行了横断面比较研究。 共有 1010 名学生（508 名来自丹麦和 502 名来自以色列）完成了问卷，评估有关配子保存的知识、看法和意图。

结果

以色列超过 70% 的男女认为女性在 35 岁及以上开始生育能力下降。共有 60% 的丹麦女性和 51% 的丹麦男性选择 29-34 岁作为生育率下降的开始时间。大约 95% 的丹麦学生选择 20-29 岁作为冷冻卵子的最佳年龄，而以色列的相应数字为 85%，不分性别。总体而言，51% 的以色列女性表示她们极度或非常担心未来的不孕症，而丹麦女性的这一比例为 31%，以色列男性的比例为 26%，丹麦男性的比例为 12%。关于保存意图，未发现性别差异。大约 3% 的以色列学生表示他们会考虑保留配子，而丹麦学生的这一比例为 14%。

结论

这些发现表明，丹麦和以色列妇女普遍担心她们未来的生育能力。丹麦学生报告更多地意识到与年龄相关的生育能力下降。这项研究的独特之处在于纳入了男学生。初步调查结果显示，男性对生育未来的担忧较少。
