Increasing numbers of women are undergoing oocyte or tissue cryopreservation for medical or social reasons to increase their chances of having genetic children. Social egg freezing (SEF) allows women to preserve their fertility in anticipation of age-related fertility decline and ineffective fertility treatments at older ages. The purpose of this study was to summarize recent findings focusing on the challenges of elective egg freezing. We performed a systematic literature review on social egg freezing published during the last ten years. From the systematically screened literature, we identified and analyzed five main topics of interest during the last decade: (a) different fertility preservation techniques, (b) safety of freezing, (c) usage rate of frozen oocytes, (d) ethical considerations, and (e) cost-effectiveness of SEF. Fertility can be preserved for non-medical reasons through oocyte, embryos, or ovarian tissue cryopreservation, with oocyte vitrification being a new and optimal approach. Elective oocyte cryopreservation is better accepted, supports social gender equality, and enhances women's reproductive autonomy. Despite controversies, planned oocyte cryopreservation appears as a chosen strategy against age-related infertility and may allow women to feel that they are more socially, psychologically, and financially stable before motherhood.
越来越多的女性出于医疗或社会原因选择进行卵母细胞或组织冷冻保存,以增加其生育遗传后代的机会。社会卵子冷冻(SEF)使女性能够在预期到年龄相关的生育能力下降和高龄时生育治疗效果不佳的情况下,保留自己的生育能力。本研究的目的是总结最近的研究结果,重点关注选择卵子冷冻的挑战。我们对过去十年中发表的关于社会卵子冷冻的文献进行了系统的综述。从系统筛选的文献中,我们确定并分析了过去十年中的五个主要关注话题:(a)不同的生育力保存技术;(b)冷冻的安全性;(c)冷冻卵母细胞的使用率;(d)伦理考虑;(e)SEF 的成本效益。可以通过卵母细胞、胚胎或卵巢组织冷冻保存来保留非医疗原因的生育能力,其中卵母细胞玻璃化是一种新的、最佳的方法。选择卵子冷冻保存更易被接受,支持社会性别平等,并增强了女性的生殖自主权。尽管存在争议,但计划中的卵子冷冻保存似乎是一种针对年龄相关不孕的选择策略,并且可以让女性在生育前感到自己在社会、心理和经济上更加稳定。
