辅助生殖技术对子代出生缺陷的Meta分析

辅助生殖技术对子代出生缺陷的Meta分析摘要：辅助生殖技术是一项先进的医学技术，它可帮助许多不孕不育夫妻实现生育梦想，但是现代技术的缺陷可能会影响子代的健康。本文使用Meta分析对辅助生殖技术对子代出生缺陷的影响进行评估。通过搜索PubMed、WebofScience、ProQuest和CNKI数据库，共筛选出79篇相关的研究文章。研究发现，辅助生殖技术的使用可能会增加小儿先天畸形、婴儿死亡率和儿童癌症等风险，但是其影响变异性较大，生殖技术的类型、治疗周期、卵子和精子的来源、年龄和健康状况等因素对其影响也可能存在差异。因此，患者在选择辅助生殖技术时需要谨慎，并根据自身情况进行风险评估和个性化的治疗。此外，更多的研究还需要开展，以更好地了解辅助生殖技术对子代出生缺陷的潜在风险。
