This review explores the ethical and medical challenges faced by women of advanced maternal age who decide to have children. Assisted reproductive technologies (ARTs) make post-menopausal pregnancy physiologically plausible, however, one must consider the associated physical, psychological, and sociological factors involved.
A quasi-systematic review was conducted in PubMed and Ovid using the key terms post-menopause, pregnancy + MeSH terms [donations, hormone replacement therapy, assisted reproductive technologies, embryo donation, donor artificial insemination, cryopreservation]. Overall, 28 papers encompassing two major themes (ethical and medical) were included in the review.
There are significant ethical considerations and medical (maternal and fetal) complications related to pregnancy in peri- and post-menopausal women. When examining the ethical and sociological perspective, the literature portrays an overall positive attitude toward pregnancy in advanced maternal age. With respect to the medical complications, the general consensus in the evaluated studies suggests that there is greater risk of complication for spontaneous pregnancy when the mother is older (eg, >35 years old). This risk can be mitigated by careful medical screening of the mother and the use of ARTs in healthy women. In these instances, a woman of advanced maternal age who is otherwise healthy can carry a pregnancy with a similar risk profile to that of her younger counterparts when using donated oocytes.
本综述探讨高龄孕产妇决定生育时所面临的伦理和医学挑战。辅助生殖技术使绝经后妊娠在生理上成为可能,然而,必须考虑其中涉及的相关身体、心理和社会学因素。
在PubMed和Ovid数据库中进行了一项半系统综述,使用的关键词为绝经后、妊娠+医学主题词[捐赠、激素替代疗法、辅助生殖技术、胚胎捐赠、供体人工授精、冷冻保存]。该综述共纳入28篇涵盖两个主要主题(伦理和医学)的论文。
绝经前后女性妊娠存在重大伦理考量以及医学(母体和胎儿)并发症。从伦理和社会学角度审视时,文献对高龄孕产妇妊娠总体持积极态度。关于医学并发症,评估研究中的普遍共识表明,母亲年龄较大(如>35岁)时自然妊娠的并发症风险更高。通过对母亲进行仔细的医学筛查以及在健康女性中使用辅助生殖技术,这种风险可以得到缓解。在这些情况下,身体健康的高龄孕产妇使用捐赠卵母细胞时,其妊娠风险与年轻孕产妇相似。
