Are IVF Medications in Thailand the Same as in China: Core Answer

IVF medications used in Thailand and China are essentially the same in terms of pharmacological action, drug categories, and routes of administration. They are all based on gonadotropins (FSH, LH), GnRH agonists, GnRH antagonists, hCG, and luteal support medications (progesterone, hCG, etc.). Differences mainly lie in brand origin, doctor protocol habits, drug packaging specifications, and regulatory approval pathways. For patients, there is no essential difference in drug efficacy and safety between the countries, but the choice and usage method need to be evaluated based on specific circumstances.

Module B: Why Does This Question Arise

Why Does the Question "Thailand vs. China Medications" Arise

This question mainly arises from three aspects:

• Information Asymmetry: Some intermediaries or unofficial channels, for marketing purposes, deliberately exaggerate inaccurate claims like "Thailand medications are more advanced" or "Domestic medications are inferior," leading to cognitive bias in patients.
• Brand Perception Differences: The Thai market indeed predominantly uses imported brands (such as Gonal-f, Puregon, Crinone), while China has both domestic and imported options. Patients easily equate "imported" with "better."
• Different Regulatory Systems: The approval standards and registration catalogs of China's NMPA and Thailand's Thai FDA differ. A few medications available in Thailand are not yet marketed in China, and vice versa, which also creates a direct perception of "difference."

Module E: Differences Between Countries

China vs. Thailand IVF Medications: Three Core Differences

1. Brand and Source Differences

Drug Category	Common Brands in China	Common Brands in Thailand
Gonadotropins (FSH)	Gonal-f (imported), Lishenbao (domestic), Puregon (imported)	Gonal-f, Puregon, Menopur
GnRH Antagonists	Cetrotide (imported), Orgalutran (imported)	Cetrotide, Orgalutran
Luteal Support (Progesterone)	Crinone (imported), Duphaston (imported), Yimaxin (domestic)	Crinone, Utrogestan, Cyclogest
hCG	Ovidrel (imported), HCG (domestic)	Ovidrel, Pregnyl

It can be seen that the core drug categories highly overlap, but domestic alternatives are almost non-existent in Thailand. The Thai market is dominated by original European and American drugs. This does not mean better efficacy but results from different market structures and medical insurance policies.

2. Differences in Doctor Protocol Preferences

Thai doctors tend to prefer flexible individualization in protocol selection, especially with extensive experience in antagonist protocols and mild stimulation protocols. Chinese doctors are more accustomed to classic protocols like long protocols and short protocols, but in large reproductive centers, the degree of individualization is also very high. This difference stems from different training systems and clinical pathways, not the drugs themselves.

3. Differences in Regulation and Purchasing Channels

In China, all assisted reproductive drugs must be prescribed by qualified reproductive centers with a prescription, and personal cross-border purchases are prohibited. Thailand allows patients to purchase some medications at pharmacies with a doctor's prescription, but it is also strictly regulated. Patients should note: Personally purchasing drugs from abroad is illegal, and the cold chain storage and authenticity of the drugs cannot be guaranteed.

Module H: Most Common Pitfalls

Four Most Common Pitfalls

• Blindly Believing "Thailand Medications Are Better": Drug efficacy depends on suitability for individual circumstances, not origin. There is no significant difference in core efficacy between imported and domestic drugs.
• Self-purchasing Drugs from Abroad: Some patients buy Thai medications through agents, risking counterfeit, expired, or improperly stored drugs, with no traceable source.
• Arbitrarily Switching Brands: Although different brands may have the same active ingredients, there are minor differences in excipients, purity, and bioavailability. Doctors need to adjust dosages based on patient response; self-switching is not allowed.
• Ignoring Protocol Compatibility: The usage, dosage, and timing of the same drug differ completely in different protocols. Simply comparing "which drug is used" without considering the overall protocol design can be misleading.

Module N: Special Situation Handling

Drug Selection Differences in Special Situations

Poor Ovarian Response (POR)

For patients with low AMH and low antral follicle count, Thai doctors are more inclined to use high-dose stimulation protocols or add LH (e.g., adding human menopausal gonadotropin hMG), while Chinese doctors may adopt mild stimulation protocols or natural cycles. Both approaches have their rationale; the difference lies in protocol philosophy, not the drugs.

Polycystic Ovary Syndrome (PCOS)

PCOS patients are sensitive to ovulation induction drugs and prone to OHSS. Thai doctors commonly use antagonist protocols combined with GnRH agonist trigger to reduce OHSS risk; this strategy is also widely used in China. There is no essential difference in drug use, but dosage adjustment habits may vary.

Advanced Maternal Age

For women aged ≥38, both Thai and Chinese doctors tend to use high-dose FSH or add growth hormone (GH) to improve oocyte quality. However, it should be noted that the use of growth hormone in assisted reproduction is currently still considered "off-label use," and some centers in China are more cautious about its application.

Module R: Practitioner Observations

Practitioner Observations: The Gap Between Reality and Patient Perception

In practice, we find that patients' perceptions of "Thailand medications" often fall into two extremes: one is believing that Thai medications are "all imported and therefore more effective"; the other is worrying that Thai medications "have different ingredients and Chinese doctors won't know how to use them." Both views are inaccurate.

The reality is: Drugs are tools; protocol design is the core. An experienced doctor, whether using domestic or imported drugs, can make precise adjustments based on the patient's hormone levels (FSH, LH, E2, P4) and follicular growth rate. Patients should focus on the doctor's clinical experience and protocol logic, rather than simply comparing drug brands.

Additionally, some patients report "better follicular growth after using medication in Thailand," which is often related to protocol differences rather than the drugs themselves. Thai doctors monitor more frequently during stimulation (daily or every other day ultrasound + hormone testing) and make adjustments more promptly; this is the key factor.

Module F: Differences Between Hospitals

Differences in Medication Protocols Among Thai Reproductive Centers

Even within Thailand, different reproductive centers have different medication usage habits:

• Large Private Hospitals (e.g., BNH, Bumrungrad, Piyavate): Almost exclusively use original imported drugs, with diverse protocol options and a high proportion of antagonist protocols.
• Specialized Clinics (e.g., iBaby, Jetanin): Also primarily use imported drugs but tend to be more conservative in dosage, focusing on individualized fine-tuning.
• Public Hospitals (e.g., Chulalongkorn Hospital): Some drugs may use local generics or more cost-effective alternatives, but core drugs remain primarily imported.

Overall, imported drugs account for over 90% of the Thai market, which is in stark contrast to China. However, it must be emphasized: A high proportion of imported drugs ≠ higher success rates; there is no direct causal relationship between the two.

Module Q: Frequently Asked Questions

Five Most Common Patient Questions

1. Can I bring Thai medications back to China for use? — No. Personal cross-border drug purchase is illegal, and cold chain storage and drug authenticity cannot be guaranteed.
2. Will Chinese doctors use Thai medications? — Chinese doctors use brands and protocols they are familiar with. It is not recommended to bring your own drugs and ask the doctor to use them.
3. Are Thai medications better than domestic ones? — There is no essential difference in efficacy. The choice should be based on the doctor's advice and individual circumstances.
4. What tests need to be prepared in advance for IVF in Thailand? — You need to provide reports for AMH, hormone panel (6 items), semen analysis, infectious disease screening, chromosome karyotype, etc. Some tests have limited validity.
5. Are medication costs for IVF in Thailand higher than in China? — Overall, medication costs in Thailand are slightly higher than in China (due to the high proportion of imported brands), but the difference is usually within an acceptable range.
