1、 Why is the trend of assisted reproduction in the United States continuing to rise

Over the past decade, the average annual growth rate of assisted reproductive technology (ART) worldwide has remained at around 7%, with the United States consistently occupying the dual high ground of technology and regulations. The latest Annual Report on Assisted Reproductive Technology released by the Centers for Disease Control and Prevention (CDC) shows that in 2022, the United States completed over 320000 embryo transfer cycles, with an overall live birth rate of 48.7%. Among them, the live birth rate of single embryo transfer for patients under 35 years old exceeded 55%. At the same time, the US Food and Drug Administration (FDA) and the Society for Reproductive Medicine (ASRM) have implemented strict supervision on laboratory quality control, clinical ethics, drug cold chain, and infection control, promoting reproductive centers across the United States to maintain global leadership in key areas such as embryo culture, cryoresuscitation, genetic screening, and uterine membrane synchronization.

For cross-border medical patients, American hospitals generally adopt the; Full process responsibility system for attending physicians; From initial diagnosis, ovulation induction, egg retrieval to transplantation, all are led by the same senior physician, avoiding the common practice in China; Segmented approach; Disadvantages of seeking medical treatment; In addition, with the independent prescription review system of American pharmacists, the dosage and compatibility of ovulation promoting drugs can be accurately adjusted to 0.01 mg, significantly reducing the incidence of ovarian hyperstimulation (OHSS). In addition, reproductive centers in the United States are generally equipped with a complete set of auxiliary technologies such as EmbryoScope+time-of-flight imaging, AI based blast grading, Intralipid immune regulation, ERA endometrial receptivity testing, Hatch Aid laser assisted hatching, etc., providing more solutions for difficult cases.

5、 Standard procedures and timeline for IVF in the United States

Regardless of which institution is chosen, the clinical pathway for IVF in the United States is generally consistent and can be roughly divided into the following seven stages:

1. Remote first visit (Day 0-7)Submit six hormone tests for both spouses AMH、 Semen analysis, hysteroscopy/hysterosalpingography, eight reports on infectious diseases, etc; Make a 30 minute video call with the attending physician to determine the preliminary plan.
2. Pre cycle conditioning (Day 8 – 21)Women take oral multivitamins, coenzyme Q10, and DHEA (if needed), while men supplement with zinc, selenium, and L-carnitine; Synchronize visa processing and apartment booking.
3. Launch in the United States (Day 22)On the second day after arrival, go to the hospital for filing, fingerprint recording, blood test+ultrasound; The doctor adjusts the ovulation induction plan (antagonist/rectangular plan/micro stimulation) based on the basic FSH and antral follicle count.
4. Promotion and Monitoring (Days 23-30)Monitor E2, LH, P4 and follicle diameter daily or every other day; Ovulation is triggered when the dominant follicle is ≥ 18 mm and E2 ≈ 200-300 pg/ml per follicle.
5. Egg retrieval and fertilization (Day 31)Transvaginal puncture under intravenous anesthesia, with an average of 10-15 minutes; Using ICSI or conventional fertilization, observe the prokaryotic cells after 16-18 hours.
6. Embryo Culture and Testing (Days 32-37)Cultivate to D5/D6 blastocysts and perform PGT-A/PGT-M as appropriate; Using AI or manual dual scoring, select the best blastocyst for freezing.
7. Cryotransplantation (Day 45-60)When the thickness of the endometrium is ≥ 8 mm and the blood flow is good, perform single blastocyst thawing and transplantation; Blood test for β - HCG 10 days later, and ultrasound confirmation of fetal heart rate 4 weeks later.

Overall, it takes an average of 8-10 weeks from remote initial diagnosis to confirmation of pregnancy, with a stay in the United States of approximately 20-25 days.

6、 Cost composition and financial planning

It is recommended to prepare a total budget of $35000 to $40000, including medical expenses, airfare, apartments, meals, and insurance, which can cover one ovulation induction and one transplant.

7、 Visa, Insurance, and Legal Notice

• Visa:It is recommended to apply for a B1/B2 tourist visa for IVF in the United States. During the interview, truthfully explain the medical purpose, bring a hospital appointment letter, financial proof, and return flight ticket order.
• Insurance:American reproductive centers usually do not include IVF in basic medical insurance, but can purchase short-term medical accident insurance (≤ 90 days), covering accidental egg retrieval anesthesia, ovarian torsion emergency, etc.
• law:There is no unified federal assisted reproductive law in the United States, and there are significant differences among states. California, Nevada, and Illinois are relatively friendly towards reproductive healthcare, and the court supports clarifying parent-child relationships; New York State passed the Family Planning Act in 2021, allowing for a legal contractual framework. It is recommended to confirm the document list with a professional lawyer in advance to ensure the smooth processing of birth certificates, passports, and travel permits.

8、 Frequently Asked Questions Expert Q&A

1. With only 3 basal follicles left in premature ovarian failure, is there still hope for going to the United States?

INCINTA's Dr. Lin pointed out that there is still a chance to obtain diploid embryos with AMH<0.5 ng/ml, and the key lies in individualized ovulation promotion: first orally taking estrogen for 2 weeks to suppress FSH, and then using a high-purity LH+FSH mixture, combined with growth hormone (GH) and DHEA, can increase the egg retrieval rate by about 30%.

Will single embryo transfer reduce the success rate?

RFC统计显示，<38岁女性单囊胚移植的累计活产率（一次取卵多次移植）达72%，twin pregnancy妊娠率仅1.8%，远低于双胚胎移植的35%。单胚胎移植并不会削弱整体妊娠机会，反而显著减少早产、妊娠高血压等产科风险。

Does freezing embryos affect the health of babies?

Boston IVF followed up 12000 frozen blastocyst babies born between 2014 and 2022, with a birth defect rate of 1.9%, which was not statistically different from the natural conception population; Vitrification freezing technology has stabilized the embryo recovery rate at around 99% without increasing the risk of chromosomal abnormalities.

Can I pay in installments for IVF in the United States?

The top 5 hospitals all cooperate with third party financial institutions to provide interest free or low interest installment plans for 6-24 months; Partial institutional support; Cycle Failure Refund Plan; If three transplants do not result in a live birth, 50% of the medical expenses will be refunded, but additional insurance will need to be purchased, with a premium of approximately $4000.

How to reduce the risk of multiple pregnancies?

严格实行"单囊胚+冷冻移植"策略，结合ERA检测确保子宫内膜同步；对twin pregnancy妊娠高风险人群（身高<155 cm、子宫畸形、既往剖宫产）优先选择单胚胎，必要时进行宫颈环扎预防早产。

9、 Decision tree when choosing a hospital

Step 1: Identify personal issues - ovarian function, endometrium, male semen, immune factors;
Step 2: Compare CDC data - prioritize centers with a live birth rate of>50% in the same age group;
Step 3: Evaluate Chinese services - whether there are consultants stationed in China, WeChat Q&A, and international drug express delivery;
Step 4: Calculate the total budget - medical+living+legal, reserve 15% contingency fund;
Step 5: Confirm the doctor's schedule - Popular doctors need to make an appointment 2-3 months in advance;
Step 6: Sign informed consent - carefully read the terms regarding embryo disposal, freezing period, and overdue fees.

10、 Conclusion

The core reason why assisted reproductive technology is highly favored in the United States is that; High success rate+rigorous quality control+ethical transparency;. INCINTA, RFC, SCRC, NYC Fertility, and Boston IVF each have their own unique characteristics, covering the complete chain from difficult ovarian dysfunction to endometrial thinning, from immune regulation to embryonic genetic screening. As long as physical preparation, financial planning, and legal studies are fully done, going to the United States for IVF is not out of reach. May every family seeking children be able to welcome a healthy new life under the premise of science, safety, and compliance.
