三代试管婴儿（PGT，胚胎植入前遗传学检测）的成功率受多种因素影响，但总体而言，其一次成功率（即单次移植的活产率）显著高于常规试管婴儿，尤其是对于特定人群。以下是关键数据和分析：
一、总体成功率范围活产率（单次移植）
65%~75%（适用于年轻、卵巢功能良好且胚胎质量高的患者）。 40%~60%（35岁以上或存在胚胎因素/子宫问题的患者）。 数据来源：美国生殖医学学会（ASRM）及大型生殖中心统计。
与传统试管的对比
二、影响成功率的核心因素
三、如何提高一次成功率？严格筛选胚胎
个性化移植方案 移植前调理 心理与生活方式
四、理性看待“一次成功”
五、真实案例参考
建议：与生殖医生详细沟通个体化预期，通过完善移植前检查（如宫腔镜、免疫评估）最大化成功概率。即使首次未成功，调整方案后仍有较高机会！ 🌱
The success rate of third-generation IVF (PGT, pre implantation genetic testing) is influenced by various factors, but overall, its one-time success rate (i.e., the live birth rate of a single transfer) is significantly higher than that of conventional IVF, especially for specific populations. Here are the key data and analysis: 1、 Overall success rate range Live birth rate (single transplant) 65%~75% (suitable for young patients with good ovarian function and high embryo quality). 40%~60% (for patients over 35 years old or with embryonic factors/uterine problems). Data source: American Society of Reproductive Medicine (ASRM) and large reproductive center statistics. Comparison with traditional test tubes The single transfer live birth rate of second-generation test tube (ICSI) is about 50%~60%, and the third generation can be increased by 10%~15% by screening healthy embryos. 2、 Core factors affecting success rate Embryo quality After PGT screening, the success rate of high-quality embryo transfer (such as diploid blastocysts) is significantly improved, but about 20% to 30% of embryos still fail to implant due to other factors (such as endometrium and immunity). female age <35 years old: The live birth rate can reach over 70%. 35-40 years old: Decreased to 50% -60% (due to increased embryo abnormality rate caused by egg aging). >40 years old: may be below 40%, requiring more cycles to accumulate embryos. Uterine environment When the thickness of the endometrium is ≥ 7mm, there are no adhesions/polyps, and the blood flow is good, the success rate is higher. other health problems When thyroid dysfunction, insulin resistance, immune factors, and other factors are not controlled, the success rate may be reduced. 3、 How to increase the success rate once? Strictly screen embryos PGT-A (aneuploidy screening) can exclude embryos with chromosomal abnormalities and reduce miscarriage rates. If there is a monogenic disease (such as thalassemia), PGT-M can block the transmission of genetic diseases. Personalized transplantation plan Adjust the transplantation time based on ERA detection, or use natural/artificial cycles to optimize endometrial synchrony. Conditioning before transplantation Control blood sugar and blood pressure, supplement folic acid and vitamin D, and improve endometrial blood flow (such as aspirin and low molecular weight heparin). Psychology and Lifestyle Excessive stress can affect endocrine function. It is recommended to maintain moderate exercise and psychological counseling. 4、 Rationally view 'one success' The cumulative success rate is higher: if the first attempt is unsuccessful, the cumulative live birth rate of subsequent transfers of the remaining frozen embryos can reach 80% to 90%. It should be combined with one's own situation: for example, elderly or premature ovarian failure patients may need multiple ovulation induction cycles to accumulate enough embryos. 5、 Real case reference Ideal scenario: A 30-year-old female with 5 blastocysts, 3 normal after PGT, and a single transplant success rate of 75% to 80%. Challenge situation: A 42 year old female obtained 2 blastocysts, but only 1 was normal after PGT, with a success rate of about 40% to 50%. Suggestion: Communicate in detail with a reproductive doctor about individualized expectations and maximize the probability of success by improving pre transplant examinations such as hysteroscopy and immune assessment. Even if the first attempt is unsuccessful, there is still a high chance after adjusting the plan! 🌱
