Over the same period, births kept falling. Thailand recorded fewer than 417,000 births in 2025, the lowest figure in about 75 years. <strong>This guide brings together the latest Thai national registry analysis, government birth registration figures, WHO infertility estimates and carefully labelled UK comparisons.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Data years matter. The Thai registry study was published in 2026 but analyses treatment through 2023. Birth registration figures run to 2025. The two series cover different years and measure different things, <strong>so the rise in treatment does not explain the fall in births, or the reverse.<\/strong> The latest UK regulator report covers 2024, with some birth outcomes still preliminary. None of the national or UK results below are Genesis Fertility Center&#8217;s own treatment results.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key takeaways<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Thailand recorded 105,354 initiated ART cycles across 2017\u20132023. Its 2023 total was <strong>18,189, the highest year in the registry table.<\/strong><\/li>\n\n\n\n<li>From 13,610 initiated cycles in 2017 to 18,189 in 2023, activity rose approximately 33.6% on the registry paper&#8217;s Table 1 figures.<\/li>\n\n\n\n<li>Thailand recorded about 462,000 births in 2024, the first year below 500,000 since 1949, and fewer than 417,000 in 2025. That is about 46,000 fewer births in one year.<\/li>\n\n\n\n<li>Frozen embryo transfers were 94.7% of reported Thai embryo transfers in 2023. That is a treatment-mix measure, not a success rate.<\/li>\n\n\n\n<li>Thailand&#8217;s 2023 clinical pregnancy rate per transfer was 52.0% for frozen transfers and 33.7% for fresh transfers. Neither is a live-birth rate or a patient-specific prediction.<\/li>\n\n\n\n<li>The UK reported a 30% live-birth rate per embryo transferred in 2024; those birth outcomes are preliminary and are not Thai clinic results.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Thailand&#8217;s births fell below 500,000 in 2024 and kept falling in 2025<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Thailand recorded 462,240 births and 571,646 deaths in 2024. It was the first year with fewer than 500,000 births since 1949, and deaths outnumbered births again. In 2025, births fell to fewer than 417,000, with 559,684 deaths, according to Department of Provincial Administration registration data reported by Thai media.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td>Year<\/td><td>Registered births<\/td><td>Registered deaths<\/td><\/tr><\/thead><tbody><tr><td>2024<\/td><td>462,240<\/td><td>571,646<\/td><\/tr><tr><td>2025<\/td><td>Fewer than 417,000<\/td><td>559,684<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Source: Department of Provincial Administration registration data, as reported by Khaosod English (2025), Thairath (2026) and the Bangkok Post (2026).

These are population and demographic indicators, not clinical infertility rates.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Falling births may involve changes in when people form families, financial pressures, preferences, partnership patterns and reproductive health. It would be wrong to infer that everyone in a low-birth-rate country needs fertility treatment, or that more IVF cycles alone can reverse a national birth trend.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"492\" src=\"https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/Untitled-Visual-1-2-1024x492.png\" alt=\"Infographic showing five factors influencing falling birth rates in Thailand: family formation, financial pressures, personal preferences, changing partnership patterns, and reproductive health.\" class=\"wp-image-45732\" srcset=\"https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/Untitled-Visual-1-2-1024x492.png 1024w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/Untitled-Visual-1-2-300x144.png 300w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/Untitled-Visual-1-2-768x369.png 768w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/Untitled-Visual-1-2-1536x738.png 1536w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/Untitled-Visual-1-2-368x177.png 368w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/Untitled-Visual-1-2-410x197.png 410w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/Untitled-Visual-1-2-838x403.png 838w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/Untitled-Visual-1-2.png 1872w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How much IVF and ART treatment takes place in Thailand?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The most useful national starting point is the Thai ART registry analysis covering 2017\u20132023.

Activity dipped in 2020 and 2021 and then recovered. Volume is not a direct measure of infertility prevalence, treatment quality or the number of individual patients.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Source discrepancy to understand.<\/strong> The registry paper&#8217;s abstract and narrative describe 11,924 as the number of initiated cycles in 2017, while Table 1 places 11,924 in the frozen-transfer column and 13,610 in the initiated-cycle column. This article uses the internally consistent table total rather than the conflicting narrative figure.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frozen versus fresh embryo transfers: what the data show<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Frozen embryo transfer (FET) accounted for 79.5% of reported Thai transfers in 2017 and 94.7% in 2023. In 2023, the registry counted 15,913 frozen and 884 fresh embryo transfers.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td>Thailand, 2023<\/td><td>Frozen transfer<\/td><td>Fresh transfer<\/td><\/tr><\/thead><tbody><tr><td>Share of embryo transfers<\/td><td>94.7%<\/td><td>5.3%<\/td><\/tr><tr><td>Clinical pregnancy per transfer<\/td><td>52.0%<\/td><td>33.7%<\/td><\/tr><tr><td>Average embryos per transfer<\/td><td>1.34<\/td><td>1.42<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Source: Thai ART registry analysis, Table 1 and accompanying results. Clinical pregnancy means a pregnancy identified clinically, such as by ultrasound; it is not the same endpoint as a live birth.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 18.3-percentage-point difference between the 2023 clinical pregnancy rates is a descriptive observation, not proof that freezing improves outcomes for every patient. People selected for frozen and fresh transfers can differ in embryo availability, medical history, treatment protocols and other characteristics. The number of fresh transfers is also much smaller.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Thai study additionally reports a 36.3% live-birth rate per frozen embryo transfer in 2021, compared with a 29.5% global benchmark drawn from ICMART reporting. Treat that as published contextual benchmarking, not a like-for-like clinic comparison: patient mix, coverage and reporting practices may differ.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Planning treatment? Read the Genesis frozen embryo transfer guide to understand the clinical process, then ask a specialist whether frozen or fresh transfer is appropriate for your history.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Who appears in Thailand&#8217;s ART registry?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The registry study reports that approximately 70% of the people in its study population were aged 35 or older. That helps describe the treated population, not the proportion of all Thai people who are infertile.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its leading reported indications for treatment included unexplained infertility (23.0%), ovulatory disorders (15.5%) and other female-factor infertility (14.9%). These categories reflect reasons recorded among patients receiving ART, not population-wide causes of infertility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Patient age, ovarian reserve, sperm factors, previous treatment and the reason for referral all affect how a clinic should interpret any success statistic. For individuals, the national average is only a starting question.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Safety: embryo numbers and ovarian hyperstimulation<\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" width=\"600\" height=\"400\" src=\"https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/2.png\" alt=\"Close-up of an embryologist using a laboratory pipette to handle samples in a petri dish under a microscope during IVF laboratory work.\" class=\"wp-image-45738\" style=\"width:840px;height:auto\" srcset=\"https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/2.png 600w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/2-300x200.png 300w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/2-369x246.png 369w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/2-410x273.png 410w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">In 2023, the Thai registry reported an average of 1.34 embryos transferred per frozen transfer and 1.42 per fresh transfer. Across stimulated cycles in the 2017\u20132023 analysis, severe ovarian hyperstimulation syndrome (OHSS) was reported at 0.4%. These are different denominators: embryos per transfer and severe OHSS per stimulated cycle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Embryo-transfer decisions also need to account for the risks of multiple pregnancy. For international context, the HFEA reported that 88% of UK IVF cycles involved single-embryo transfer in 2023, while the preliminary multiple-birth rate from IVF was 3.4%. Those UK figures describe a different regulatory and clinical setting, so they should not be treated as equivalent Thai outcomes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How common is infertility?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The World Health Organization estimated that 17.5% of adults globally experience infertility at some point in their lives, with lifetime estimates of 17.8% in high-income countries and 16.5% in low- and middle-income countries. These are lifetime prevalence estimates rather than the share currently using IVF.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A low national birth rate is not the same as high infertility prevalence. A total fertility rate counts births per woman across a population; infertility is a clinical condition.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">IVF success rates by age: what UK benchmarks can and cannot tell us<\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"400\" src=\"https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/3.png\" alt=\"Smiling couple lying together on a bed in a bright bedroom, illustrating family planning and fertility treatment considerations.\" class=\"wp-image-45741\" style=\"width:840px;height:auto\" srcset=\"https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/3.png 600w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/3-300x200.png 300w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/3-369x246.png 369w, https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2026\/10\/3-410x273.png 410w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">For age-specific comparison, the UK Human Fertilisation and Embryology Authority (HFEA) reported an average 30% IVF live-birth rate per embryo transferred in 2024, compared with 20% in 2014. In 2024, the rate was 38% for patients aged 18\u201334 and 8% for those aged 43\u201344.

A personal assessment is more informative than any headline success-rate figure.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">How many babies were born in Thailand in 2025?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fewer than 417,000, according to Department of Provincial Administration registration data reported by Thai media. It was the second year in a row below 500,000 and the lowest total in about 75 years.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is IVF use rising in Thailand while births fall?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The national registry shows initiated ART cycles rose from 13,610 in 2017 to 18,189 in 2023. Births have fallen over a similar period. The two series cover different years and different populations, so one does not explain the other.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the latest reported IVF success rate for Thailand?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">There is no single clinic-neutral percentage that predicts success for every patient. In a Thai national registry analysis published in 2026, the 2023 clinical pregnancy rate was 52.0% per frozen embryo transfer and 33.7% per fresh embryo transfer. These are clinical pregnancy outcomes, not live-birth rates or clinic guarantees.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does frozen embryo transfer work better than fresh transfer?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Thailand&#8217;s observed frozen-transfer clinical pregnancy rate was higher in 2023, but a registry comparison cannot determine which approach is superior for one patient. The groups differ and the fresh-transfer sample was much smaller. The clinical team should discuss the appropriate strategy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is 2023 data in an article updated in 2026?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Registry collection, validation and research publication take time. The national Thai study used here was published in August 2026 and covers procedures from 2017 through 2023. The data year is not the publication year.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is Thailand&#8217;s low birth rate the same as high infertility prevalence?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. A total fertility rate counts births per woman across a population; infertility is a clinical condition. A low national birth rate can reflect many social, economic and demographic factors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Methodology, limitations and sources<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Updated October 2026. We selected public, attributable numerical results from a WHO prevalence report, a UNFPA Thailand policy brief, Thai government birth registration data as reported by national media, a peer-reviewed analysis of Thailand&#8217;s national ART registry and UK HFEA reports. We identify reporting years, distinguish clinical pregnancy from live birth and avoid combining unlike denominators. Derived growth is calculated from the Thai registry&#8217;s Table 1 values; the paper&#8217;s conflicting 2017 narrative figure is disclosed above. Birth and ART figures cover different years and are presented side by side, not as cause and effect. This page will be updated each year when new registry and birth data are published.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">HFEA comparability note: its 2024 age-specific outcome chart includes specified treatments using patients&#8217; own eggs and excludes PGT-A\/M\/SR, donor eggs, surrogacy and cases without recorded birth outcomes.
