Hum Reprod:放心吧,试管婴儿不会比自然受孕的孩子“傻”

一项最新研究表明,年龄在3岁至11岁之间的人工受孕的孩子,其阅读和口语测试成绩要比自然受孕的孩子更高些。



一项最新研究表明,年龄在3岁至11岁之间的人工受孕的孩子,其阅读和口语测试成绩要比自然受孕的孩子更高些

研究人员数百名通过体外受精(IVF)或精子卵浆内注射技术(ICSI,用于精子计数较低的不育病例)出生的英国儿童的数据进行了分析,每隔几年就对同一组儿童进行测试直至他们年满11岁。研究人员发现,在这些孩子长到三至五岁期间,人工受孕与认知发育之间存在正相关。

发表在《人类生育学》杂志上的这项研究还表明,接受人工受孕治疗的父母一般都比那些自然受孕生子的父母年龄更大些、受教育程度更高些、社会经济地位也更高。部分人工受孕的婴儿更可能是多胎妊娠或是低出生体重,然而,这项研究发现,他们的家庭背景“覆盖”了可能对健康造成的负面影响,如认知能力较差。这项发现极有意义,因为之前有一些研究表明,辅助生殖治疗会损害孩子的认知能力。

来自牛津大学社会学系和纳菲尔德学院的研究人员Melinda Mills教授和博士研究生Anna Barbuscia使用的数据来自英国千禧队列研究当中来自全国的具有代表性的18,552个家庭。

社会学系的Melinda Mills教授说,“研究结果表明,通过人工生殖技术受孕的儿童,其家庭背景的积极作用“覆盖”了损害认知能力等相关的健康状况欠佳的风险。虽然人工受孕的婴儿出现早产或多胎妊娠的风险更高,但是我们发现,他们的父母年龄较大、受教育程度较高且来自高收入阶层。”

这些都是与孩子预后更好的因素。重要的是,这种积极影响是长期性的,超过11岁。研究结果表明,综上所述,这种生育治疗不会损害孩子的高级思维能力。
