研究目的:

本研究旨在评估高龄(>=35岁)且有胚胎移植失败史或首次移植失败、仍有冻存囊胚的患者中,采用无创染色体筛查(NICS)与形态学结合的胚胎优选策略的临床效果。具体目标包括: 评估NICS与形态学联合策略的效果:采用“解冻—短时复苏培养—NICS检测—复冻”策略,对高龄患者的冻融胚胎进行染色体评估,并结合形态学评分进行胚胎选择。比较“形态学”与“NICS+形态学”策略对妊娠结局的影响,包括持续妊娠率、临床妊娠率、流产率等。 优化高龄患者冻存胚胎的优选路径:提供无创筛查方法,减少胚胎侵入性操作,提高胚胎选择精准性,减少非整倍体胚胎移植风险,优化妊娠结局。 提供真实世界循证依据:为高龄患者提供NICS与形态学联合评估冻存胚胎选择的证据,推动NICS技术的临床应用。 探索NICS的临床价值:通过大规模、多中心的前瞻性研究,评估NICS在不同临床条件下的应用效果,为高龄IVF患者提供更科学合理的胚胎筛选方案,尤其是针对冻存囊胚的患者。  

Objectives of Study:

Evaluate the effectiveness of the NICS and morphology combined strategy: The strategy of “thawing—short-term recovery culture—NICS testing—refreezing” will be used to assess the chromosomal status of embryos in elderly patients before frozen-thawed embryo transfer (FET), combined with morphological grading for embryo selection. The impact of the “morphology” and “NICS + morphology” strategies on pregnancy outcomes, including sustained pregnancy rate, clinical pregnancy rate, miscarriage rate, etc., will be compared.Optimize embryo selection pathways for elderly patients with cryopreserved embryos: Provide a non-invasive screening method to reduce embryo-invasive procedures, improve embryo selection accuracy, reduce the risk of aneuploid embryo transfer, and ultimately optimize pregnancy outcomes.Provide real-world evidence for clinical practice: Provide reliable evidence for selecting cryopreserved embryos based on NICS and morphological assessment without embryo biopsy, promoting the clinical application of NICS technology, especially its effectiveness and feasibility in real-world clinical settings.Explore the clinical value of NICS as an embryo selection method: Through a large-scale, multicenter prospective study, assess the application of NICS under different clinical conditions and provide a new, scientifically reasonable embryo screening approach for elderly IVF patients, especially for those with cryopreserved blastocysts.
