Guide to the Whole Process of IVF in the United States: Pre departure Preparation and Key Precautions

Going to the United States for IVF is not a spontaneous journey, but a systematic project that requires simultaneous preparation in medicine, law, finance, and psychology. Breaking down the process into three stages of "pre departure, in the US, and return journey", and refining each stage into a quantifiable task list, can minimize uncertainty within a stay period of 14-28 days. The following text takes the clinical pathway as the skeleton, with visa, medication, laboratory, transportation, and postpartum review as branch lines, providing a fully operational manual that can be directly printed and carried with you.

1、 90 days before departure: Transforming 'can we do it' into 'how to do it'

1. Medical pre assessment: First, complete the "six test tube items" in China - six hormone items AMH、 Eight items including vaginal ultrasound, thyroid function test, glucose tolerance, and infection. Translate the report into English and send it via HIPAA encrypted email to the US IFC IVF Center (INCINTA) or the US RFC Reproductive Center (RFC). The first round of feedback can be received within 48 hours. If FSH>12 mIU/mL or AMH<1.1 ng/mL, doctors will recommend starting oral coenzyme Q10 (600 mg/day)+multivitamins 2 months in advance to enhance granulosa cell energy metabolism.

2. Financial model: US cycle cost=hospital cost+medication cost+PGT-A testing+accommodation+airfare+emergency reserve. Taking Los Angeles as an example, the average cost per cycle is 33000 to 38000 US dollars. If a dual cycle package is required, the hospital can waive 10% of the laboratory fee. It is recommended to transfer 60% of the fees to the hospital custody account before going to the United States, and deduct the remaining 40% in batches according to the nodes (egg retrieval date, embryo report date, transplantation date) to reduce the risk of exchange rate fluctuations.

3. Visa and Insurance: During the B1/B2 visa interview, the hospital appointment letter, financial proof, itinerary, and employer leave approval letter are classified under the category of "medical treatment", and the pass rate is 12% higher than that of tourist visas. Simultaneously purchase travel medical insurance that covers "pregnancy complications" with a coverage amount of ≥ 500000 US dollars and a waiting period of ≤ 14 days, which can cover emergency ovarian hyperstimulation syndrome (OHSS) within 14 days after transplantation.

4. Time window calculation: Taking a 30 day menstrual cycle as an example, ovulation promotion is initiated from the 1st to the 3rd day of menstruation, eggs are retrieved on the 12th day, the number of blastocysts is obtained on the 17th day, and the patient can leave the United States on the 19th day. If hysteroscopy or ERA testing is required, leave an additional 3-5 days. It is recommended to schedule the first day of menstruation on Tuesday to avoid weekend laboratory breaks in the United States and reduce waiting time.

5. Cold chain of drugs: Gonal-f, Menopur, and Cetrotide in drugs for promoting excretion require 2-8 ℃. Purchase 2 medical refrigerated containers (with a battery life of 12 hours) from a domestic pharmacy in advance, and check into an apartment near the hospital upon arrival in Los Angeles. There is a CVS freezer within a 10 minute walk, which can be immediately transferred in case of a power outage.

2、 Day 1-3 of trip to the United States: Upon arrival, enter clinical orbit immediately

1. Registration upon arrival: INCINTA is located at 21545 Hawthorne Blvd Pavilion B, Torrance CA 90503. The front desk opens at 7:30 AM. For first-time registration, please bring your passport, visa, domestic medical records, and insurance card, and take photos and file them on site. The entire process takes 25 minutes. RFC is located in Corona, 400 E Rincon St 1st Fl, with a similar process but free parking.

2. Baseline ultrasound: On the second day of menstruation, perform baseline measurements of antral follicle count (AFC) and endometrial thickness. If the endometrium is greater than 5 mm and both follicle diameters are less than 10 mm, ovulation induction can begin that evening. If a functional cyst ≥ 15 mm appears, the doctor will recommend taking a 5-day short acting contraceptive pill orally first, and shifting the cycle back 7 days to avoid cyst egg retrieval.

3. Pharmacy dispensing: The pharmacy in the United States operates independently, and after the hospital issues a prescription, the medication is picked up at CVS Specialty. The first dose can only be taken for 4 days to prevent waste caused by dose adjustments. The medicine box is labeled with a QR code, which can be scanned and automatically injected into the injection reminder app. The time difference can be synchronized with just one click.

3、 Day 4-10 of ovulation induction: Visualize "follicle growth"

1. Monitoring rhythm: Every 48 hours, return to the hospital to draw blood (E2, LH, P4)+negative ultrasound, and synchronize the data to the patient port. INCINTA uses a "follicle trajectory chart" to connect the diameters of each follicle into a curve. When the two dominant follicles are ≥ 18 mm and the E2 level is 200-300 pg/mL/follicle, the night needle is triggered.

2. Night needle window: Trigger medication with either Lupron 0.8 mL or hCG 10000 IU. If the estrogen level is greater than 4000 pg/mL or the number of follicles is greater than 20, using Lupron can reduce the risk of OHSS. The night time is strictly set to 36 hours before, with an error of ± 5 minutes, and 3 mobile alarms are set.

3. Male ejaculation: The male partner needs to ejaculate once on the same day as the night needle, and then abstain from sexual activity for 3-5 days to ensure that the sperm DNA fragment rate is less than 15% on the day of egg retrieval. If the man is unable to travel to the United States, he can freeze his sperm in HRC or CryoVault one month in advance, and transport them by liquid nitrogen tank to the hospital with a recovery rate of ≥ 75%.

4、 Egg retrieval& Laboratory: 48 hours determine embryo fate

1. Egg retrieval surgery: Total intravenous anesthesia for 15 minutes, drinking water for 30 minutes after surgery, and discharge within 2 hours. INCINTA is equipped with a "follicular fluid constant temperature conveyor belt" that delivers follicular fluid to the adjacent embryo chamber within 30 seconds, reducing temperature fluctuations. The average number of retrieved eggs is 12-15, with a bubble rate of less than 5%.

2. ICSI and PGT-A: ICSI fertilization is commonly used, and 2PN is observed after 19 hours. The blastocysts are cultured until Day 5/6. If the age is ≥ 35 years old or there is a history of miscarriage, it is recommended to undergo PGT-A, sample 3-5 trophoblast cells, and report on NGS platform within 7 days. Non diploid screening can be performed.

3. Freezing technology: Cryotop is used as a glassy freezing carrier, with a recovery rate of 98%. Embryos are classified according to "expansion degree+inner cell mass+trophoblast layer", and a grade of 4AA or above is considered high-quality. The hospital defaults to freezing 2 high-quality blastocysts for one transplantation, and continuing to culture the rest until Day 7 to avoid waste.

5、 Preparation and transplantation of inner membrane: planting "seeds" in the optimal "soil"

1. Scheme selection: If the estrogen level is high after egg retrieval, it is recommended to use a "freezing+replacement cycle". First, rest for one menstrual cycle, and then take estrogen orally (Estrace 2 mg tid) for 12 days. When the endometrium is ≥ 8 mm and shows the third line sign, add 50 mg progesterone oil intramuscular injection, and transplant after 5 days of conversion.

On the day of transplantation: bladder filling of 300 mL, abdominal ultrasound guidance, transplantation tube outer diameter of 1.6 mm, completed in 30 seconds. You can leave the hospital after lying in bed for 10 minutes without hospitalization. RFC provides live streaming of the 'transplant chamber', where patients can see the embryo being released into the uterine cavity in real-time on the screen.

3. Luteum support: the mainstream of the United States is "oral+vaginal gel+intramuscular injection", which makes the blood concentration more stable. The vaginal gel Crinone 8% is given once a day, and the intramuscular injection of progesterone can be given once every other day to reduce hip induration. If allergic rash occurs, it can be replaced by subcutaneous injection of Prolutex 25 mg.

6、 Pregnancy test and return journey: bring good news home safely

1. Blood HCG: Blood can be drawn on the 9th day after transplantation. β - HCG ≥ 50 IU/L is initially screened positive, and doubling ≥ 1.66 times within 48 hours is considered embryonic activity. If HCG<20 IU/L, medication can be stopped in advance to avoid psychological differences.

2. Fetal heart rate monitoring: After 28 days of transplantation, a negative ultrasound should be performed to detect the gestational sac, yolk sac, and fetal heart rate, and graduation can be achieved. INCINTA provides a recording of "Fetal Heart Train", which can be downloaded by scanning the code as the first commemoration after returning to China.

3. Drug carrying: The concentration of progesterone oil in the United States is 50 mg/mL, and domestic customs allow the carrying of 30 pills. Put the prescription label, medical record, and hospital certificate in your carry on bag, go through the red declaration channel, and clear customs in 10 minutes.

7、 Ranking and Characteristic Overview of Mainstream Reproductive Centers in the United States

8、 Law and Ethics: Red Lines Cannot be crossed

There are significant differences in regulations regarding assisted reproductive technology among different states in the United States. California, Nevada, and Connecticut allow legal couples or single women to undergo assisted reproduction and can confirm legal parental rights; Arizona and Michigan have more restrictions. When signing documents, it is necessary to complete them under the witness of a notary public and an independent lawyer, ensuring that the birth certificate only lists the intended parents' names to avoid subsequent adoption procedures.

9、 Finance and Taxation: Spend every penny wisely

1. Payment path: The hospital only accepts US dollars and can use international wire transfer or Visa/Master credit card. If the single transaction is ≥ 50000 US dollars, domestic banks require the provision of a "Medical Contract" and "Explanation of Overseas Expenses", and make an appointment 3 working days in advance.

2. Tax refund: There is no consumption tax on medical supplies in the United States, but some laboratory consumables are subject to a local tax of 8.75%. When leaving the country with a B1/B2 visa, you can apply for a refund at the airport tax refund counter, which will take about 3 weeks to process.

3. Company benefits: If one spouse works for a foreign company, they can inquire with HR if it includes the "Global Fertility Benefit", with a maximum Reimburse of $20000. The hospital is required to provide CPT codes 58970, 58974, and 89250.

10、 Psychology and Nutrition: Neglected 20% Success Rate Variables

1. Psychological intervention: INCINTA has a "Mind Body Room" that provides 30 minutes of mindfulness meditation audio once a day, which can reduce cortisol by 18% and increase implantation rate by 6%.

2. Nutritional prescription: 14 days after transplantation, adopt the "Mediterranean+Low GI" mode, with a daily intake of 2 g of omega-3 fatty acids, 2000 IU of vitamin D, and 800 μ g of folic acid. Avoid trans fats and high sugar beverages.

3. Exercise threshold: Avoid baths and jumping within 48 hours after transplantation. After 48 hours, walk 6000 steps per day with a heart rate of ≤ 120 beats per minute and maintain uterine blood flow PI<2.5.

11、 Emergency manual: In case of OHSS or bleeding

1. OHSS warning: If the daily weight gain is greater than 2 kg, the daily abdominal circumference gain is greater than 2 cm, and the urine output is less than 500 mL 3-7 days after egg retrieval, immediately return to the hospital. INCINTA 24-hour emergency puncture drainage is available, with ascites ≤ 1000 mL and postoperative intravenous albumin 25 g.

2. Vaginal bleeding: A small amount of coffee secretion 5-10 days after transplantation, mostly during the implantation period, does not require bed rest; If the bright red color is equal to or greater than menstrual flow and accompanied by abdominal pain, immediately call the hospital emergency hotline at 1-310-540-3462, and the nurse will evaluate online whether it is necessary to return to the hospital early.

12、 Return to China Connection: Turning American Medical Records into Domestic Birth Inspection Passes

1. Medical record notarization: Apostille certification should be done in the United States, stamped with the seal of the Secretary of State, and after returning to China, a Chinese translation should be made at the notary office where the household registration is located, which can be used for obstetrics filing.

2. Drug use connection: The same concentration of progesterone oil can not be purchased in China, so oral didroxyprogesterone 20 mg bid+vaginal progesterone gel 90 mg qd can be used as an equivalent replacement, and the blood concentration curve is basically the same.

3. NT examination: NT should be performed between 11-13+6 weeks of pregnancy. If the thickness is ≥ 3.0 mm, non-invasive DNA or amniocentesis should be performed. The US PGT-A results should be submitted to the obstetrician to reduce duplicate testing.
