This study addresses various outcomes and follow-up of children born after IVF-surrogacy. Recent reports on perinatal outcome after IVF-surrogacy and on data generated by the Society of Assisted Reproductive Technology (SART) Registry between 1991 and 1995 were examined. A review of recently published perinatal outcomes of children born after IVF-surrogacy, including the developmental information of 110 children after the first 2 years of life, was undertaken. The birth weights for singleton pregnancies following IVF-surrogacy and IVF were similar, whereas the birth weights of twins and triplets born from the IVF-surrogates were significantly heavier than those delivered from conventional IVF patients. Preterm delivery was increased in twin and triplet gestations in all segments analysed. The incidence of low birth weight was significantly lower in children born after IVF surrogacy than in those born after IVF, for all births recorded. The incidence of congenital abnormalities following IVF and IVF-surrogacy was within the expected range for spontaneous conceptions. Speech delays were predominant in the multiple births, but neither speech nor motor delays persisted at 2 years of age in children born after IVF-surrogacy. These findings would imply that a gestational carrier would provide potential environmental benefits for the infant.
本研究探讨了体外受精-代孕出生儿童的各种结局及随访情况。研究分析了近期关于体外受精-代孕围产期结局的报告以及1991年至1995年间辅助生殖技术协会(SART)登记处生成的数据。对近期发表的体外受精-代孕出生儿童的围产期结局进行了综述,包括110名儿童出生后头两年的发育信息。体外受精-代孕单胎妊娠的出生体重与体外受精单胎妊娠相似,而体外受精-代孕双胎和三胎的出生体重明显高于传统体外受精患者分娩的双胎和三胎。在所有分析的孕周中,双胎和三胎妊娠的早产率均有所增加。记录的所有出生中,体外受精-代孕出生儿童的低出生体重发生率明显低于体外受精出生儿童。体外受精和体外受精-代孕后先天性异常的发生率在自然受孕的预期范围内。多胎出生的儿童中言语延迟较为常见,但体外受精-代孕出生儿童在2岁时言语和运动延迟均未持续存在。这些发现表明代孕载体可能为婴儿提供潜在的环境益处。
