In Vitro Fertilization Success & PGD Success
IVF Success: USA • IVF Success: Europe • IVF Success: Canada
IVF Success: Thailand • IVF Success: Worldwide
IVF PGD success in Thailand rivals that of Europe and North America.
In recent years, however, some fertility doctors running Thai IVF centers in Bangkok, perhaps pressured by the high overhead of their swanky facility in pricey Thai business districts, have greatly exaggerated their IVF success rates and tremendously inflated their statistics.
One reproductive doctor, whose public relations spin doctors promote as one of Thailand's most “emminent” and “busiest”, said his success rate was 60% — higher than anyone else on the planet.

No hospital in Thailand and no Bangkok IVF doctor can perform a “miracle” and achieve anywhere near 60% IVF success.
As spin doctor Joseph Goebbels PhD, Reich Minister of Propaganda in Nazi Germany, said: “If you tell a lie big enough and keep repeating it, people will eventually come to believe.” Don't believe it.
Goebbels also said: “The truth is the mortal enemy of the lie.” Let's kill the bold lie with some facts.
The 11-year-old Synphaet Medical Assisted Reproduction Technology Center (S.M.A.R.T. Center) led by fertility Dr Napadon Yaibuates MD is confident enough to tell the truth with no need to “lie big”. He plainly states that over the years his infertility center has had a “success rate of about 30-40%”.
Reproductive doctor Napadon's PGD success for gender selection is 100%. PGD worldwide is 99% successful in gender selection.
There are many ways an infertility center can enhance and improve “IVF success” without actually improving its performance. Several common methods of doctoring IVF success statistics include:
- A fertility center can decline to provide infertility treatment to women with higher than normal BMI (Body Mass Index) because obesity clearly has a negative impact on IVF success. They are about 11% more prone toward miscarriage. In many European hospitals women with BMI 30 or more are not accepted for IVF. In the USA, few clinics accept women with BMI 35 or more.
- Older women are turned away as unsuitable candidates because their chance of IVF success is substantially less than younger women. Egg quality rapidly declines after 35.
- Fertility treatment can be terminated, a cycle ended, and the record expunged when too few eggs are produced so the attempt will not appear in the facility centers official report of IVF success.
- Women with elevated FSH can be refused fertility treatment because their chance of IVF success is also very limited.
FSH-Friendly & Age-Friendly Fertility Hospital
IVF over 45? IVF over 50?
Synphaet Medical Assisted Reproduction Technology Center is “FSH-friendly” and “age-friendly”.

Synphaet Hospital and Dr Napadon Yaibuates (นพ.นภดล ใยบัวเทศ) accept any woman having difficulty trying to conceive a child and will accept any infertile couple.
If the couple trying to conceive can accept the statistical probability of IVF success relevant to their case he will do his utmost to help them have a test tube baby.
Dr Napadon accepts women over 41. He has accepted women up to 46 years old trying to get pregnant. He has no maximum age for a woman he will accept for IVF or ICSI and he still enjoys a higher than average IVF success rate.
Synphaet Hospital and Dr Napadon accept women regardless of their FSH, including women with FSH in the range of 15-20+. And he still has a higher than average IVF success rate.
Synphaet Hospital Bangkok (โรงพยาบาลสินแพทย์) Medical Complex is a large, world class, full service health care facility. It is accredited by JCI and certified ISO 9001:2000 compliant. It has a top fertility dr. It has it's own embryology lab. It's SMART fertility center provides a full range of infertility treatment 7-days per week to anyone who needs help.
The hospital is accredited by Thailand's public Healthcare Accreditation Institute. The infertility center is certified by the Reproductive Medicine Subcommittee of the Royal Thai College of Obstetricians and Gynecologists (RTCOG).
RTCOG is a member of the International Federation of Gynecology and Obstetrics (FIGO) — the only global organization of it's kind with associations in 124 countries.
RTCOG reports (and you will find it again stated in your lengthy Informed Consent Form you must understand & sign before any infertility treatments begins): “The average success rate of IVF in Thailand is around 32.2% per embryo transfer, or 27.2% per oocyte retrieval cycle or 24.3% per initiated cycle.”
Actually, those numbers are out of date and do not reflect IVF success rates of the past several years, not even as recent as 2007. Thai IVF success since 2008 has not yet been published.
Note that the IVF success rate of Dr Napadon ranks high among fertility doctors nationwide.
All Thailand's licensed assisted reproductive technologies (ART) centers are legally obligated to report annually to the ART Registry of the Reproductive Medicine Subcommittee of RTCOG regarding:
- number of patients;
- cycles;
- ART techniques used; and
- treatment outcomes

In the March 2011 issue of the Journal of Obstetrics and Gynecology Research (Volume 37, Issue 3, pp. 236–244), Teraporn Vutyavanich (รศ.น.พ.ธีระพร วุฒยวนิช Chair of RTCOG Reproductive Medicine Subcommittee, left signature on the SMART Center license, and Associate Professor of Chiang Mai University Faculty of Medicine's Department of Obstetrics and Gynecology and Head of it's Reproductive Medicine Division), Waraporn Piromlertamorn and Jason Ellis aggregated and retrospectively analyzed the statistics from all infertility centers for 2001–2007.
The goal of the report was to help patients, clinicians and policy makers understand the current situation of ART practice in Thailand. This journal report is available from the USA National Library of Medicine database.
The authors categorized cycles into: a) fresh and b) frozen/thawed embryo transfer (FET) cycles. They discovered:
- Initiated cycles in category a) for 2001-2007, respectively were:
- 2001: 2,183
- 2002: 2,112
- 2003: 2,780
- 2004: 2,717
- 2005: 3,458
- 2006: 3,579 and
- 2007: 4,288.
- The average pregnancy rate for in vitro fertilization (IVF) was:
- 28.9% per retrieval (range, 26-32.3%) or
- 33.8% per transfer (range, 30.7-38.6%).
- 89.3% of multiple pregnancies were twins.
- Total multiple pregnancies from all treatment procedures during this period were 11.4% (range, 9.2-14.5%).
- From 2001 to 2007, IVF embryos per transfer went from 4.1 to 2.9, with no reduction in pregnancy rates.
- ICSI (oocyte insemination by intracytoplasmic sperm injection) was used more often than IVF
- IVF and ICSI have almost totally replaced GIFT (gamete intrafallopian transfer) and ZIFT (zygote intrafallopian transfer).
If any Bangkok hospitals, if any hospitals in Thailand, if any Thai IVF reproductive doctor, if any fertility center in Thailand, tells you they do “a thousand cases per year” or “hundreds per month” or have a success rate significantly higher than 38.6% (such as 47-60%) for ANY infertility treatment, then you should get out of there fast.
As we already mentioned above, USA CDC reports 31.3% of assisted reproductive technology cycles performed in America in 2008 resulted in a live birth IVF baby. Thailand's rate compares favorably but rest assured nobody in Thailand is substantially more successful than infertility doctors in North America or Europe.
IVF pregnancy rates are NOT affected by number of embryos implanted. Number of babies IS affected.
Availability and quality of assisted reproductive technologies such as IVF, ICSI and FET (frozen embryo transfer) varies greatly between countries because of fertility rates, insurance coverage, the age of women, and national economies. Accurate comparison of IVF success rates between countries is complicated because of different legal systems, cultures, religions, practices & guidelines. But statistics do give you some idea of how well Thailand compares to the rest of the world.
Worldwide, assisted reproductive technologies result in the birth of about 250,000 test tube babies annually.
According to the May 2009 issue of the European reproductive medicine journal “Human Reproduction”, availability of treatment for infertility is least in Ecuador and most in Israel. The global trend during the past decade has been fewer embryo transfers but higher pregnancy rates, ICSI being used more often than IVF everywhere, and fewer multiple births. In the Middle East, ICSI is used for 92% of infertility treatments. Dr Napadon recommends ICSI for all his patients.
Infertility treatment in Thailand compares very favorably with assisted reproductive technologies success worldwide which “Human Reproduction” says is a:
- 22% IVF success rate;
- 21% ICSI success rate;
- 15% FET success rate; and a
- multiple birth rate per delivery of 25.7%.
IVF success rate in Thailand, and particularly the IVF success rate of Dr Napadon's SMART Center compares favorably with Canada.
According to information released on the ResearchGate scientific network by Joanne Gunby regarding the 7th Annual Report of the Canadian ART Register, couples undergoing fertility treatment in Canada during 2007 using assisted reproductive technologies, including in vitro fertilization IVF, ICSI and FET:
- clinical pregnancy rate was 35.6%
- live birth rate was 28.6%
- multiple birth rate per delivery was 30.2%
- in 69% of cycles only 1-2 embryos were transferred
- ICSI was used in 68% of cycles
- using donor eggs increased pregnancy rate to 44.6% and live birth rate to 36.1%, but reduced multiple birth rate to 26.5%
- FET using the eggs of infertile women resulted in clinical pregnancy rate of 23.7%, a live birth rate of 17.8% (down from previous year) and a multiple birth rate of 24.15% (up from previous year).
Thai IVF success rates also compare favorably with those of Europe. The European IVF Monitoring Group of the European Society of Human Reproduction and Embryology reported at their 26th annual meeting in June 2010 that ICSI is now used more than twice as often as IVF in 32 European countries. They also reported:
- a European IVF success rate of 33%; with
- 20.5% of those being twins; and
- 0.8% being triplets.
Your chances of returning home pregnant after in vitro fertilization, ICSI, PGD, FET or other infertility treatment with Dr Napadon Yaibuates at his 11-year-old Synphaet Medical Assisted Reproduction Technology Center (SMART Center) is nearly as high as Europe or North America but at a fraction of the cost.
Contact Dr Napadon and the SMART Center in Bangkok today to make an appointment to begin infertility treatment at the start of you next menstrual cycle.
