Infertility is estimated to affect as many as 186 million people worldwide. Although male infertility contributes to more than half of all cases of global childlessness, infertility remains a woman's social burden. Unfortunately, areas of the world with the highest rates of infertility are often those with poor access to assisted reproductive techniques (ARTs). In such settings, women may be abandoned to their childless destinies. However, emerging data suggest that making ART accessible and affordable is an important gender intervention. To that end, this article presents an overview of what we know about global infertility, ART and changing gender relations, posing five key questions: (i) why is infertility an ongoing global reproductive health problem? (ii) What are the gender effects of infertility, and are they changing over time? (iii) What do we know about the globalization of ART to resource-poor settings? (iv) How are new global initiatives attempting to improve access to IVF? (v) Finally, what can be done to overcome infertility, help the infertile and enhance low-cost IVF (LCIVF) activism?
An exhaustive literature review using MEDLINE, Google Scholar and the keyword search function provided through the Yale University Library (i.e. which scans multiple databases simultaneously) identified 103 peer-reviewed journal articles and 37 monographs, chapters and reports from the years 2000-2014 in the areas of: (i) infertility demography, (ii) ART in low-resource settings, (iii) gender and infertility in low-resource settings and (iv) the rise of LCIVF initiatives. International Federation of Fertility Societies Surveillance reports were particularly helpful in identifying important global trends in IVF clinic distribution between 2002 and 2010. Additionally, a series of articles published by scholars who are tracking global cross-border reproductive care (CBRC) trends, as well as others who are involved in the growing LCIVF movement, were invaluable.
Recent global demographic surveys indicate that infertility remains an ongoing reproductive problem, with six key demographic features. Despite the massive global expansion of ART services over the past decade (2005-2015), ART remains inaccessible in many parts of the world, particularly in sub-Saharan Africa, where IVF clinics are still absent in most countries. For women living in such ART-poor settings, the gender effects of infertility may be devastating. In contrast, in ART-rich regions such as the Middle East, the negative gender effects of infertility are diminishing over time, especially with state subsidization of ART. Furthermore, men are increasingly acknowledging their male infertility and seeking ICSI. Thus, access to ART may ameliorate gender discrimination, especially in the Global South. To that end, a number of clinician-led, LCIVF initiatives are in development to provide affordable ART, particularly in Africa. Without access to LCIVF, many infertile couples must incur catastrophic expenditures to fund their IVF, or engage in CBRC to seek lower-cost IVF elsewhere.
Given the present realities, three future directions for research and intervention are suggested: (i) address the preventable causes of infertility, (ii) provide support and alternatives for the infertile and (iii) encourage new LCIVF initiatives to improve availability, affordability and acceptability of ART around the globe.
据估计,全球有多达 1.86 亿人受到不孕不育的影响。尽管男性不育导致了全球一半以上的不孕不育,但不孕不育仍然是女性的社会负担。不幸的是,世界上不孕率最高的地区往往是那些获得辅助生殖技术(ART)机会最少的地区。在这些环境中,妇女可能会被抛弃,面临无子的命运。然而,新出现的数据表明,使 ART 能够获得并负担得起是一项重要的性别干预措施。为此,本文概述了我们对全球不孕不育、ART 和不断变化的性别关系的了解,提出了五个关键问题:(i)为什么不孕不育是一个持续存在的全球生殖健康问题?(ii)不孕不育对性别有什么影响,这些影响是否随着时间的推移而变化?(iii)我们对 ART 在资源匮乏地区的全球化有什么了解?(iv)新的全球倡议如何努力改善 IVF 的可及性?(v)最后,我们能做些什么来克服不孕不育,帮助不孕不育夫妇,并加强低成本 IVF(LCIVF)的积极性?
使用 MEDLINE、Google Scholar 和耶鲁大学图书馆提供的关键字搜索功能(即同时扫描多个数据库)进行了全面的文献综述,确定了 2000-2014 年期间在以下领域的 103 篇同行评议期刊文章和 37 篇专著、章节和报告:(i)不孕不育人口统计学,(ii)ART 在资源匮乏地区的应用,(iii)资源匮乏地区的性别与不孕不育,以及(iv)LCIVF 倡议的兴起。国际生育协会联合会监测报告特别有助于确定 2002 年至 2010 年期间 IVF 诊所分布的重要全球趋势。此外,跟踪全球跨境生殖保健(CBRC)趋势的学者以及参与不断发展的 LCIVF 运动的学者发表的一系列文章也非常有价值。
最近的全球人口统计调查表明,不孕不育仍然是一个持续存在的生殖问题,具有六个关键的人口统计特征。尽管过去十年(2005-2015 年)全球 ART 服务大规模扩张,但在世界许多地区,ART 仍然无法获得,特别是在撒哈拉以南非洲,大多数国家仍然没有 IVF 诊所。对于生活在这种缺乏 ART 的环境中的妇女来说,不孕不育的性别影响可能是毁灭性的。相比之下,在 ART 丰富的地区,如中东,不孕不育的负面性别影响随着时间的推移而逐渐减弱,特别是随着国家对 ART 的补贴。此外,男性越来越多地承认自己的男性不育,并寻求 ICSI。因此,获得 ART 可能会减轻性别歧视,尤其是在全球南方。为此,一些由临床医生领导的 LCIVF 倡议正在开发中,以提供负担得起的 ART,特别是在非洲。没有 LCIVF 的帮助,许多不孕不育夫妇必须承担灾难性的费用来资助他们的 IVF,或者从事 CBRC 以在其他地方寻求更便宜的 IVF。
鉴于目前的现实情况,提出了三个未来的研究和干预方向:(i)解决可预防的不孕不育原因,(ii)为不孕不育夫妇提供支持和替代方案,以及(iii)鼓励新的 LCIVF 倡议,以改善全球范围内 ART 的可及性、可负担性和可接受性。
