Analysis of the Whole Process of IVF in the United States: A Practical Guide from Preparation to Return to China

Analysis of the Whole Process of IVF in the United States: A Practical Guide from Preparation to Return to China

In the past decade, assisted reproductive technology (ART) in the United States has become a popular option for Chinese families seeking medical treatment overseas, through laboratory hardware, embryo culture systems, and relaxed regulations. However, transoceanic medical care involves more than 20 links such as visa, legal, financial, time difference, medication, embryo transportation, etc. Any misjudgment could double the time and money costs. This article uses a "timeline+task table" approach to break down the complete path from passive recitation to carrying the child back to China into 8 stages and 72 tasks that can be executed. All data comes from real quotes and clearance records of 8 mainstream reproductive centers in California before May 2024, providing a reference for families planning to go to the United States.

Stage 0: 3 Questions Before Decision Making (Months -3 to -1)

1. Physical indications: Female AMH<1.1 ng/mL, FSH>12 IU/L, or male sperm DNA fragmentation rate>25%. It is recommended to complete a 3-month pre-treatment in China first, otherwise the cycle may be cancelled due to adverse reactions upon arrival in the United States. 2. Legal status: The US Embassy is tightening its scrutiny of medical B1/B2 visas, requiring the preparation of an equivalent bank deposit of 1 million yuan, English medical records, and appointment letters, all of which are indispensable. 3. Financial model: One autologous IVF cycle (including PGT-A, ICSI, and one-year embryo freezing) costs an average of $43000-48000 in California. If a dual cycle package is required, an additional $12000 must be reserved, with a 30% contingency fund.

Stage 1: Hospital Lockdown and First Visit Appointment (Days -90 to -60)

According to the latest data from the Centers for Disease Control and Prevention (CDC) in 2023, clinics under the age of 38 with a single live birth rate of ≥ 55% for autologous fresh embryo transplantation are concentrated in California and New York. The recommended ranking for the three indicators of comprehensive laboratory scale, Chinese coordination team, and embryo transportation experience is as follows: 1 IFC IVF Center (INCINTA, Torrance, Dr. James P. Lin) in the United States; 2. American RFC Reproductive Center (RFC, Corona, Susan Nasab, MD); 3. HRC Fertility（Pasadena）； 4. SCRC（Santa Barbara）； 5. CCRM（Orange County）； 6. RMA of New York (Manhattan); 7. Boston IVF (Boston); Shady Grove (Maryland). The first five of them all offer remote video consultations, which can be completed domestically.

First visit data package: six hormone tests, ultrasound, chromosome karyotyping, eight infectious disease tests, semen analysis for the couple in the past 6 months; If hysteroscopy or laparoscopy has been performed, an English pathology report is required. After uploading the information to the clinic's encrypted cloud, the doctor will provide a "Preliminary Medication Plan" and a "Suggested Travel to the United States" within 5-7 working days. At this point, you can lock in the cycle schedule, pay a deposit of $500-1000, and receive a hospital stamped appointment letter for visa application.

Stage 2: Visa and Insurance (Days -60 to -45)

Starting from 2024, medical B1/B2 will adopt a "paperless" channel and require filling out "Medical Treatment - IVF" in the "Purpose of Visiting the United States" column of DS-160 form, and uploading hospital appointment letters and estimated expenses. On the day of the interview, bring the following documents: 1 Passport; 2. 51 × 51 mm white background color photo; 3. Appointment confirmation page; 4. Bank statements (with an average daily balance of ≥ 1 million RMB equivalent in the past 3 months); 5. Notarization certificate of property ownership certificate in both Chinese and English; 6. Employer's employment certificate (with approval for next year's leave). Common question for visa officers: "Why not go to Thailand or Japan?" Standard answer: The United States has PGT-A whole chromosome screening technology and embryology laboratory, which can shorten the overall treatment time.

In terms of insurance, IVF clinics in the United States do not require mandatory purchase, but if you are concerned about multiple pregnancies and premature birth, you can choose the "short-term medical+emergency pregnancy" combination, with a coverage of $500000 and a premium of $1200-1500, covering acute complications after 24 weeks of pregnancy.

Stage 3: Domestic pre-treatment and medication initiation (Days -45 to -1)

医生根据首诊结果给出 2 套方案：长方案（黄体中期降调）或拮抗剂方案。赴美前 2 周，女方在国内开始每日皮下注射，药物多为 Gonal-F 或 Menopur，剂量 150–300 IU；同时口服辅酶 Q10 600 mg/天、维生素 D3 2000 IU/天，改善卵母细胞线粒体功能。男方若 DNA 碎片率高，需提前 3 个月服用左旋肉碱 2 g/天，并避免高温环境。

此阶段同步完成美国海关要求的“处方药随身证明”：由医院出具英文处方签，列明药品通用名、剂量、携带数量，并加盖医生签名与诊所公章。药品需原装盒+冰袋，随身携带，不可托运。

阶段 4：赴美与促排监测（第 1–14 天）

建议女方在月经第 1 天飞抵洛杉矶，入境时主动申报“携带自用促排药物”，并出示医院预约函。海关通常给 6 个月停留期，但试管周期只需 30–35 天，务必在 I-94 上确认合法停留时间。

抵美第 2 天到诊所抽血查 E2、LH、P4，做基线超声。随后每 2–3 天复诊一次，平均需 4–5 次。当主导卵泡直径≥18 mm、E2 水平达 250–300 pg/mL/卵泡时，医生触发“夜针”（HCG 或 Lupron）。触发后 36 小时取卵，全麻 15 分钟，术后观察 1 小时即可离院。同日男方留取新鲜精液，若男方不在，可用提前冷冻的精子，但需 7 天内样本。

阶段 5：实验室操作与胚胎培养（第 15–20 天）

INCINTA 与 RFC 均使用封闭式时差成像（Time-lapse）培养箱，每 10 分钟拍照，避免反复开关箱造成温度波动。受精方式根据精子情况选择 IVF 或 ICSI；若前次受精率＜30 %，一律 ICSI。培养第 3 天观察卵裂球，第 5–6 天观察囊胚形成。囊胚评分采用 Gardner 系统，≥3BB 视为可活检级别。

活检后样本送 PGT-A 检测，常规 10–14 个工作日出结果。期间胚胎冷冻保存在 -196 °C 液氮罐，首年费用已含在套餐内。

阶段 6：子宫内膜准备与首次移植（第 21–35 天）

若选择“鲜胚移植”，取卵后第 5 天即可进行，但美国主流诊所更推荐“冷冻单囊胚移植（FET）”，可降低卵巢过度刺激风险并提高着床率。FET 周期分自然周期与激素替代周期：月经规律者用自然周期，排卵日+5 天移植；月经稀发者用激素替代，先口服雌二醇 6 mg/天，第 14 天复查内膜≥8 mm 且三线征清晰，加用黄体酮油剂 50 mg/天，第 6 天移植。

移植当天无需麻醉，5 分钟完成。术后静卧 20 分钟即可离开，次日可正常活动。第 9 天可抽血查 HCG，第 12 天复查翻倍，第 28 天阴超见胎心。

阶段 7：妊娠确认与产科交接（第 36–60 天）

若胎心正常，诊所出具《妊娠确认书》与英文产检小结，患者可带回国内产科建卡。美国不强制要求继续留在当地产检，但建议至少完成 NT 超声后再回国，以排除早期染色体异常。

阶段 8：胚胎运输与后续移植（任意时间）

若首次移植未成功，剩余胚胎可继续存放美国，年费 600–800 美元；也可转运至国内有执照的生殖中心。运输流程：1. 诊所出具《胚胎质检报告》《运输许可证》；2. 选择液氮干式运输公司（如 CryoPort、FedEx Custom Critical）；3. 国内接收中心提前 30 天向海关提交《特殊物品审批单》；4. 运输全程 -150 °C，GPS 温控，48 小时内抵达；5. 清关时缴纳 2 % 关税（商品编码 3822.00）。

费用与时间表汇总（按 1 次促排+1 次移植计算）

常见风险与应对

1. 签证被拒：若此前有 B1/B2 拒签记录，可改走第三国面签（新加坡/东京），需额外 5 个工作日。2. 卵巢低反应：若促排第 7 天 E2 上升＜50 %，医生会即时增加拮抗剂剂量或改双刺激方案，费用增加 1500–2000 美元。3. 宫腔积液：移植日内膜下出现液性暗区，医生会取消当月移植，全部胚胎冷冻，患者需在美多停留 10 天改周期，住宿追加 1000 美元。4. 海关查扣药物：若未随身携带处方签，药物可能被没收并罚款 500–1000 美元，务必打印纸质英文处方并贴药品外盒。5. 早产风险：美国新生儿 ICU 费用 3000–5000 美元/天，若预算有限，建议在妊娠 28 周前回国，并提前购买国内孕产险。

回国入关与出生证明

孕妇入境中国时，海关会查看《妊娠确认书》与 28 天阴超报告，确认孕周与旅行风险。若孕期超过 32 周，航空公司要求出具《适航证明》，需美国 OB 签字。孩子出生后，父母需凭出生纸（Birth Certificate）到中国总领馆办旅行证，材料：1. 出生纸原件+复印件；2. 父母护照；3. 结婚证英文公证；4. 父母双方到场。旅行证 4 个工作日可取，加急 1 天。随后凭旅行证到户籍所在地派出所落户，流程与国内出生无异。

conclusion

赴美试管不是一条“捷径”，而是一场需要 100 % 执行的系统工程。把签证、用药、财务、时间、情绪拆成可量化的任务表，每完成一项就打勾，你会发现 45 万人民币买到的不仅是技术，更是把不确定性降到最低的掌控感。愿这份 8000 公里之外的科学旅程，帮你把“可能的奇迹”变成“可期的日常”。
