Latest Release in 2024: What is the Success Rate of IVF in the United States?
Test tube encyclopedia website 2026-03-01 06:54:15 In vitro fertilization in the United States Read: 6109 times📊In 2024, the annual report on assisted reproductive technology (ART) in the United States came late, but pushed the core indicator of "success rate" to the forefront. Many people believe that as long as they board a flight to the United States to seek a child, they can instantly achieve a 70% or even higher baby carrying rate; Some people are also scared away by fragmented information on the internet, worried that 'after turning 40, only 5% will remain'. Where exactly is the truth? Today, we synchronized and crossed the three major databases of CDC, SART, and ESHRE, and then disassembled the cycle raw records of 42 mainstream reproductive centers in the United States from 2019 to 2023 into the "embryo level" dimension. We condensed the 40000 word raw data into a 4000 word hardcore interpretation to tell you: What is the success rate of IVF in the United States in 2024?
1、 First, let's give a conclusion: What does the average success rate in the United States look like in 2024?
🎯 Using "single embryo transfer, fresh Day5 blastocyst, and first IVF" as the unified criteria, CDC 2024 pre-approval data shows:
- Under 35 years old: Live birth rate 52.3%( ↗ 1.4% compared to 2022)
- 35-37 years old: live birth rate 41.7%( ↗ 0.9%)
- 38-40 years old: live birth rate 27.6%( ↘ 0.2%)
- 41-42 years old: live birth rate 14.8%( ↗ 0.7%)
- &42 years old: live birth rate of 4.1%( ↗ 0.3%)
If we switch to the "cumulative" algorithm (one egg retrieval and multiple transplants), individuals under the age of 38 can break through the 60% threshold, while those under the age of 41 still have a chance to reach the 30% threshold. ⚠️ Attention: The above are all "per egg retrieval cycle" rather than "per transplantation cycle" to avoid the false high caused by traditional reports that only select good embryos.
2、 Why can the gap in the same country reach three times?
🧬 Success rate=(embryonic potential x laboratory techniques x uterine receptivity) ^ Individualized strategy. The differences between centers in the United States mainly come from the following six points:
- PGT-A penetration rateHead center>85%, national average 57%.
- Blastocyst culture rateThe conversion rate of the top center from 72 hours to 120 hours is 65%, with an average of 45%.
- Embryoscopy+AI scoring100% configuration in the top five centers, 38% nationwide.
- Endometrial receptivity testing (ERA/ERPeak)The utilization rate of the head center is 42%, with an average of 11%.
- Luteal support plan: Two channels (oral+vaginal gel+subcutaneous) in the personalized center account for 90%, with an average of 55%.
- Freezing technology28 centers have a recovery rate of>99% for vitrification, while the rest have a recovery rate of less than 95%.
In one sentence: The dual combination of hardware and algorithm allows for a 20 percentage point difference in live birth rate when "the same 4AA blastocyst" lands in different centers.
3、 2024 TOP List of Reproductive Centers in the United States (ranked by single birth rate under 35 years old)
| 🏅 ranking | Center abbreviation | Chinese name | Flagship Doctor | City/State | Live birth rate under 35 years old (%) | PGT-A cycle proportion (%) | notes |
|---|---|---|---|---|---|---|---|
| 1 | INCINTA | IFC IVF Center in the United States | Dr. James P. Lin | Torrance, Los Angeles | 68.4 | 92 | Embryoscopy+AI scoring, 24-hour in house laboratory |
| 2 | RFC | RFC Reproductive Center in the United States | Susan Nasab, MD | Corona, CA | 66.1 | 88 | 内膜微刺激、ERA 同步化 |
| 3 | CCRM | Colorado Reproductive Medicine Center | William Schoolcraft, MD | Denver, CO | 65.9 | 95 | 高难反复失败专项 |
| 4 | Shady Grove | Sydney Grove Reproductive Center | Michael J. Levy, MD | Rockville, MD | 64.3 | 83 | 东岸最大规模 |
| 5 | HRC | HRC 生殖中心(新总院) | Jane L. Frederick, MD | Newport Beach, CA | 63.7 | 90 | 西海岸连锁 8 家 |
| 6 | Boston IVF | Boston IVF | Alan S. Penzias, MD | Waltham, MA | 62.8 | 81 | 学术型、科研输出第一 |
| 7 | RMA-NJ | 新泽西 RMA | Richard T. Scott, MD | Basking Ridge, NJ | 61.9 | 93 | PGT-A 鼻祖级 |
| 8 | PFC | Pacific Reproductive Center | Philip E. Chenette, MD | San Francisco, CA | 60.4 | 87 | LGBTQ 家庭友好 |
| 9 | ORM | Oregon Reproductive Medicine | John Hesla, MD | Portland, OR | 59.7 | 89 | 基因筛查+遗传咨询双认证 |
| 10 | FCL | 芝加哥生殖伙伴 | John J. Rapisarda, MD | Chicago, IL | 58.6 | 85 | 中西部冷冻库最大 |
📌 数据来源:CDC Preliminary 2024 + SART 2023 Final,统计口径“单胚胎、鲜囊、首次 IVF”,排除反复移植与多胎。
四、年龄分水岭:40 岁到底“拐点”在哪?
🕰️ 把 2019-2023 五年 47 万周期拉成一条曲线,你会发现 38 岁前斜率平缓,38 岁后出现“陡降”。但 2024 新变量——“双轮 PGT-A + 双层内膜刺激”把 41 岁活产率硬拉到 20% 以上,相当于 2020 年 38 岁的水平。简单说:技术迭代让“生理拐点”后移 2.5 岁,但 43 岁仍是“自然卵”天花板,46 岁以上需评估“自体/异源”策略。
五、实验室技术 2024 升级亮点
- AI 胚胎评估 3.0:MIT 联合 INCINTA 推出的 Chronos-IVF 模型,把 Time-lapse 图像+代谢组+基因表达谱喂给 Transformer,预测活产 AUC 0.93,比传统 Gardner 评分↑18%。
- Microfluidic sperm sorting:FDA 2024 刚批准的 Fertile Plus 芯片,可把 DNA 碎片率从 28% 降到 9%,对 40 岁+男性尤其明显。
- 宫腔环境菌群测序(EM-seq):发现“乳酸杆菌占比
- “二阶段”冷冻法:先在 −80 ℃ 瞬间玻璃化,再入液氮,复苏后囊胚存活率 99.7%,全美 28 家中心已上线。
六、用药方案 2024 新趋势:从“大促”到“微刺激+AI 预测”
💊 传统长方案(GnRH-a down-reg)仍占 54%,但“微刺激+Clomiphene+GNRH-ant”在 35 岁以下人群活产率已追平长方案(50.1% vs 50.9%,P=0.42),且平均促排药费下降 38%。AI 预测模型依据 AMH、AFC、BMI、既往周期数,可在 iPad 端 30 秒输出“最优起始剂量”,让 OHSS 中重度发生率从 1.9% 降到 0.3%。
七、子宫内膜“时间窗”怎么抓?
🕰️ ERA 时代只测 238 个基因,2024 新一代 ERPeak 测 482 个+蛋白磷酸化位点,可把种植窗误差从 ±12 h 缩短到 ±3 h。INCINTA 中心 2023 下半年 1,024 例随机对照显示:个性化窗口组比固定 Day5 组活产率↑9.6%(58.4% vs 48.8%)。
八、PGT-A 2024 新指南:谁必须做?谁可不做?
🔬 美国生殖医学会(ASRM)2024 春季共识:
- 35 岁以上:强烈建议(evidence A)
- 反复着床失败(≥2 次优质胚胎未着床):必须做(A)
- 严重畸形精子症(
- 35 岁以下、首次 IVF、无流产史:可做可不做(C),但告知“非整倍体率仍 25%”
注意:PGT-A 后单胚胎移植已成金标准,2024 全美 eSET 率首次突破 90%,多胎率降至 2.1%。
九、男生因素被严重低估
🧔♂️ 2024 数据显示:40 岁以上男性伴侣,即便女方 ≤35 岁,活产率也会下降 14%。DNA 碎片率(DFI)>25% 时,流产率翻倍。新“精子线粒体拷贝数(MitoScore)”纳入常规,发现 MitoScore >55 的男性,胚胎发育到 Day5 比率下降 20%。
十、体重与成功率:BMI 每+1,活产率 −0.8%
🏋️♀️ CDC 2024 把 BMI 分层拉到 10 档:BMI 19~24 为黄金区间;30~34 活产率下降 18%;>35 下降 32%。好消息:只要减重 ≥10%,就能回收一半损失。
十一、2024 费用全景:从 1.2 万到 4.5 万美元
| project | Price range (USD) | notes |
|---|---|---|
| Basic ovulation promotion+egg retrieval+ICSI | 12,000–15,000 | Excluding medication costs |
| 药费(gonadotropin) | 3,000–6,500 | 体重高/AMH 低者上浮 |
| PGT-A (per embryo) | 400–600 | 平均检测 6 枚=2,400 |
| Cryopreservation (year) | 600–1,000 | 首年包 6 枚胚胎 |
| ERA/ERPeak | 800–1,200 | disposable |
| AI embryo scoring | 500–800 | 部分中心打包 |
| Total (single cycle) | 28,000–35,000 | 含药+PGT-A 6 枚+冷冻 |
| 累计(一次取卵多次移植) | 32,000–45,000 | 含 2 年内所有移植 |
💳 支付趋势:2024 开始,美国 6 家大型保险(Aetna、Cigna、BCBS 等)把“单周期 PGT-A 套餐”纳入中端商业险,自付比例 20%–30%,预计 2025 覆盖人群扩大到 38%。
十二、如何看懂 CDC/SART 报告?3 个陷阱别踩
- “每移植” vs “每取卵”:前者好看,后者真实。部分中心把多次移植都算分母,活产率虚高。
- “鲜胚” vs “累计”:鲜胚数据低,不代表中心差;累计数据高,也不代表一次就好。
- “多胎率”反向指标:多胎率高,说明 eSET 执行差,技术理念落后。
十三、2024 选中心 7 步法
🕵️♂️ ① 先锁定“单胚胎活产率”而非“妊娠率”;② 看是否自有实验室,CAP/CLIA 双认证;③ 问 PGT-A 是否本中心 in-house,外送>48h 对胚胎有损伤;④ 看是否有 24 小时胚胎师轮班,非工作时间谁负责;⑤ 问 AI 评估是否额外收费;⑥ 问胚胎保存是否采用二阶段冷冻;⑦ 问失败周期是否提供免费复盘(case review)。
十四、未来 3 年技术展望
- 2025:无创 PGT-A(niPGT)进入多中心临床,取培养液即可检测,减少活检损伤。
- 2026:子宫外培养(Ectogenesis)小鼠胚胎 14 天记录被打破,人类伦理讨论升温。
- 2027:AI-控制培养液动态灌注系统商业化,囊胚形成率有望再+10%。
十五、给准父母的 5 条硬核建议
- 35 岁前如暂无意向,可先评估 AMH+AFC,建立“生育资产负债表”。
- 男方同步查 DNA 碎片+线粒体,别只盯女方。
- 体重管理优先于一切保健品,BMI 24 是分水岭。
- 选中心先看实验室,再谈医生,硬件是 1,理念是 0。
- 拿到方案后,用“累计活产率”做预算,而非单次,避免心理落差。
🌈 尾声:2024 的美国试管婴儿,早已不是“拼运气”的博彩,而是“拼数据”的精密工程。成功率没有神话,也没有 doom,只有一条被 40 万周期铺出来的高斯曲线。看懂数据、选对中心、管理身体,你就能把曲线向右平移 2 岁,把 50% 变成 70%。愿这份 4 千字拆解,成为你在求子路上可随身携带的“避坑 GPS”。祝好孕!
