The justification for offering amniocentesis to women age 35 or older is that by age 35 the risk of having a child with chromosome problem is greater than the risk of amniocentesis. In fact, this seemingly objective statement is not supported by historical analysis. Maternal age 35 was chosen for the cutoff based mostly on economic cost-benefit analysis rather than objective medical assessment. The story of why 35 was chosen illustrates how collective memory can affect, and be influenced by, the guiding ethical principles of a medical profession.
为35岁及以上女性提供羊膜穿刺术的理由是，到35岁时，生育染色体问题患儿的风险大于进行羊膜穿刺术的风险。事实上，这一看似客观的说法并未得到历史分析的支持。将35岁作为产妇年龄界限主要是基于经济成本效益分析，而非客观的医学评估。选择35岁的缘由说明了集体记忆如何影响医学行业的指导性伦理原则，并受其影响。
