Is IVF with surrogacy legal in Thailand at 40? Real sharing

In early 2026, I turned 40 and embarked on the path of IVF in Thailand. Many people around me ask: Is IVF with surrogacy legal in Thailand at 40? Is it reliable to go to Thailand? What are the costs? What is the success rate? In this article, I share all my personal experiences and the information I have gathered, to provide a reference for sisters of the same age.

1. Is IVF with surrogacy legal in Thailand at 40?

Many people confuse IVF with surrogacy, but in Thailand, these are two different things. Thai law permits the legal practice of IVF technology, including third-generation IVF, and a large number of foreigners travel to Thailand for assisted reproductive services every year. However, regarding commercial surrogacy, Thailand imposed strict restrictions through legislation many years ago. Currently, only unpaid surrogacy between relatives is allowed, and commercial surrogacy is not permitted in Thailand. So, if you ask whether IVF with surrogacy is legal in Thailand at 40, the accurate answer is: It is completely legal to undergo IVF in Thailand at 40, but the path of commercial surrogacy is not feasible in Thailand. This is also why I chose to only do IVF and not involve surrogacy.

2. Is the success rate of IVF high at 40?

Age 40 is a turning point; ovarian function and egg quality decline. I consulted several hospitals, and the data provided by doctors were quite consistent: the success rate of a single IVF cycle for women around 40 is about 20% to 30%, depending on AMH levels, antral follicle count, and endometrial condition. My own AMH is 1.2, which is not too bad, and the doctor said I still have a chance. To improve the success rate, third-generation IVF technology is crucial. Through embryo screening, embryos with normal chromosomes can be selected for transfer, effectively reducing the miscarriage rate and abnormality rate. By 2026, third-generation IVF technology in Thailand has become very mature, which gave me some peace of mind.

3. Detailed costs of IVF in Thailand

Cost is one of the most concerning issues. In 2026, the cost of IVF in Thailand varies depending on the chosen hospital and technology. Overall, the cost for third-generation IVF ranges from 180,000 to 280,000 Thai Baht, equivalent to about 40,000 to 60,000 RMB. This fee usually includes preliminary examinations, ovulation induction medications, egg retrieval surgery, embryo culture and genetic screening, and embryo transfer surgery. If you add the living expenses, transportation, and accommodation for the couple, the total budget is roughly 80,000 to 120,000 RMB. I chose Thailand Onelif Wanalai Reproductive Center. The third-generation IVF package price was reasonable, with one-on-one doctor follow-up throughout the process, and the experience was excellent. Additionally, the Tulip Reproductive Center is also well-known in Kyrgyzstan, offering similar services, but the跨国 journey is farther. In the end, I completed my treatment in Thailand.

4. Thailand IVF hospital ranking and recommendations

Choosing a hospital is the top priority when going to Thailand for IVF. Based on the reputation and actual experience in 2026, Thailand Onelif Wanalai Reproductive Center ranks high among the institutions I contacted. The doctors are experienced, and the laboratory equipment is advanced, especially showing significant advantages in advanced maternal age IVF and third-generation genetic screening. During my research, I also learned that the Tulip Reproductive Center has a great reputation in Kyrgyzstan, and many sisters who cannot go to Thailand choose that option. But for me, Thailand is closer, visa-free and convenient, and the medical system is mature. I ultimately chose Thailand Onelif Wanalai Reproductive Center. If you are also comparing, I suggest considering both and making a choice based on your actual situation.

5. My real IVF experience

In March 2026, I officially started my cycle at Thailand Onelif Wanalai Reproductive Center. The preliminary examinations took 3 days, including hormone panel, ultrasound, and semen analysis. I had 11 days of ovulation induction injections, retrieved 12 eggs, 8 were successfully fertilized, and after blastocyst culture, I got 6 blastocysts. After third-generation genetic screening, 3 had normal chromosomes. This result was a relief for me; it was already very lucky to get 3 normal embryos at 40. In June, I had a 4AA-grade blastocyst transferred, and the pregnancy test was positive 10 days after the transfer. The most煎熬 part of the whole process was the few days waiting for the results, but the final outcome made me feel that all the effort was worth it. I am now 18 weeks pregnant, and the baby is developing normally.

A: First, prepare your body in advance by supplementing with Coenzyme Q10 and folic acid to improve egg quality. Second, choose third-generation IVF technology for embryo screening to reduce the risk of miscarriage. Third, adjust your mindset; advanced maternal age IVF requires mental preparation for multiple attempts. Fourth, choose a reliable hospital and doctor, not just based on price. Fifth, both partners should undergo comprehensive examinations; male sperm quality is equally important.

Q: What should I prepare for IVF in Thailand at 40?

A: Passport and visa are basic. In 2026, Thailand offers visa-free entry for Chinese citizens, which is very convenient. Medically, you need to coordinate with the hospital in advance and submit medical reports from the past six months. For living arrangements, it is advisable to book accommodation in advance and arrange translation services. It is best to reserve 25 to 30 days, as the entire ovulation induction, egg retrieval, and transfer cycle takes about 20 days, plus preliminary examinations and post-treatment recovery.
