Nowadays, the technology of IVF in Thailand has developed to the third generation of IVF technology, second only to the United States. The success rate of IVF for normal couples in Thailand is 60-75%, second only to the United States. Thailand IVF has now developed into the third generation IVF technology, called PGD- preimplantation gene diagnosis, which is the most effective sex selection method at present, with the standard of 99%. This technology has realized the family dream for the majority of patients' families, and most patients prefer the surgical site. Thai IVF doctors studied in Britain, Australia and other western countries in their early years and introduced advanced western technology, which laid a stable foundation for the later development of IVF technology in Thailand. Now all kinds of equipment are available in Thailand. Based on the first generation, second generation and third generation test tube technology, continuous research and introduction of technologies, such as CGH technology, can effectively screen out genetic disease genes on 23 pairs of chromosomes in human body, which is more reliable than the current PGD technology.
