The demographic composition of many developed countries threatens their economies and global influence. On the one hand, the increased cost of living and of raising children discourages couples from starting families until later in life while, on the other hand, improved living standards have increased life expectancy. Together, these have resulted in a low total fertility rate and a net increase in the elderly population. The financial and employment protection incentives offered by governments have had relatively little impact on this demographic trend, and a multi-level approach is needed. Governments are, therefore, considering alternatives as part of a so-called 'population policy mix'. One option is to promote access to assisted reproductive technology for infertile couples. The prevalence of infertility has increased, in part because of general health issues, such as obesity and the rise in sexually transmitted diseases, and also because women are postponing having their first child. Improving accessibility to assisted reproductive technology will relieve the burden of infertility on these couples and may contribute to effectively challenging the problem of low total fertility rates in many developed countries.
许多发达国家的人口结构对其经济和全球影响力构成了威胁。一方面,生活成本和抚养子女成本的增加使得夫妻推迟组建家庭,直到较晚生育;另一方面,生活水平的提高延长了人们的预期寿命。这两者共同导致了总和生育率降低以及老年人口净增加。政府提供的财政和就业保护激励措施对这一人口趋势的影响相对较小,因此需要采取多层次的方法。因此,各国政府正在考虑各种替代方案,作为所谓“人口政策组合”的一部分。一种选择是为不孕夫妇提供更多获得辅助生殖技术的机会。不孕不育的发生率有所上升,部分原因是肥胖和性传播疾病增加等一般健康问题,也因为女性推迟生育第一胎。提高辅助生殖技术的可及性将减轻这些夫妇的不孕负担,并可能有助于有效应对许多发达国家总和生育率低的问题。
