Assisted reproductive technologies (ARTs), including in vitro fertilization (IVF), now account for 1.5% of all births in the USA [1]. Although the majority of children born through these technologies are healthy, ART children are at increased risk of being born with low birth weight (LBW, <2500 g) [1]. Researchers commonly attribute this outcome to parental pre-existing health conditions, medication use and/or specific aspects of ART procedures, including hormone stimulation, media culture conditions and cryropreservation [2]. Given the well-known association between LBW and chronic disease in adulthood which some evidence suggests is also elevated among ART children [2], it is important to understand any ‘additional’ factors that could be contributing to the development of LBW following ART.

辅助生殖技术，社会心理压力和低出生体重。

辅助生殖技术（ART），包括体外受精（IVF），目前占美国所有分娩的1.5％[1]。尽管通过这些技术出生的大多数儿童都是健康的，但ART儿童出生时出生体重低（LBW，<2500 g）的风险增加[1]。研究人员通常将此结果归因于父母先前存在的健康状况，药物使用和/或ART程序的特定方面，包括激素刺激，培养基培养条件和冷冻保存[2]。鉴于LBW与成年后慢性疾病之间的众所周知的关联，一些证据表明，ART儿童之间的关联也有所提高[2]，重要的是要了解任何可能在抗逆转录病毒治疗后导致LBW发展的“其他”因素。
