Success rates for all treatments

Trinidad IVF and Fertility Centre has set itself apart as one of the leaders in the region for providing clear and transparent fertility treatment success rates. Our UK accreditation means that we voluntarily allow external UK experts to audit and verify all of our published data including success rates, just like UK fertility centres are required to do by law (See HFEA UK). We are renowned for ethical treatment and producing the healthiest pregnancies with the lowest rate of multiple pregnancies in the region.

Why Are Our Success Rates So Impressive?

Our ultimate goal is to help couples build healthy families. This can only be done by having the highest quality within the fertility clinic laboratories, combined with exceptional doctors providing treatments using the latest tecniques and most effective procedures.

To achieve this our highly skilled team works diligently to stay on top of quality control and remain at the cutting edge of the fertility medical field by attneding international conferences and workshops and by undertaking research at home here in T&T to understand the unique needs of our population.

Some reasons we are so successful:

  • We use the latest technologies
  • We ensure rigorous quality control
  • We are fully accredited with IVF laboratory and fertility centre certification
  • We employ and continually train the very best staff to ensure both quality and excellence in customer service
  • We are committed to ongoing learning and research into fertility issues within T&T

IUI success rates

Each time an IUI is done the chance of becoming pregnant is between 2 – 30%. This will vary depending on your personal circumstances and will be lower particularly with lower sperm quality and in older women (40 years and over).

Trinidad IVF & Fertility Centre IUI success rates 2012 2013
Number of IUIs performed (all types) 114 109
Pregnancy rate in all women (18-45 years) 18% 17%
Pregnancy rate in women 32 years and under 19% 26%
Pregnancy rate (donor sperm) 33% 29%
Multiple pregnancy rate (twins) 3% 3%
Multiple pregnancy rate (triplets or higher) 0% 0%

If both tubes are blocked there is almost no chance of pregnancy with IUI. This is why the clinic will usually ask you to have a tube x-ray before IUI treatment.

IVF Success rates

We are justifiably proud of our IVF success rates. We report our success rates in the most transparent way, just like in the UK, in terms of pregnancies per CYCLE STARTED not pregnancies per embryo transfer or pregnanices per best quality embryo tranferrred. This means that you are getting the real answer to your question “what is my chance of getting a pregnancy if I do an IVF cycle in your clinic?”.


Please note: A comparison of clinic success rates may not be meaningful because clinics may use subtly different statistics to inflate success rates. For example the term “Pregnancy” might mean a blood test reading of a beta-HCG of three and above, of five and above, or a more advanced pregnancy of six weeks on ultrasound with a fetal heart beating. Whatever definition is used by the clinic will substantially change the apparent success rate of “percent of pregnancies”. Also the percentage number varies – it could mean pregnancies for every cycle started (including all cancelled cycles – as the UK clinics must publish), or pregnancies for each egg collection, each embryo transfer or each embryo transfer of the highest quality blastocysts only. Obviously you cannot compare pregnancy rates from the larger number of all cycles started to pregnancies from couples who just the best quality embryos (a much smaller number of cycles). The first statistic will give the same clinic an overall “success rate” of around 25%, whereas the second statistic will give the same clinic an overall “success rate” of above 70%! Another way of making “success rates” look better is to leave out cycles in all women over a certain age, as they have much lower pregnancy rates.

IVF success rate statistics for all clinics in the UK must be reported by law and are available on the website for the human fertilisation and embryology authority (HFEA). They use different ways of reporting the pregnancy rates to the USA, so the results cannot be directly compared.

The HFEA is a UK governmental agency that by law inspects clinics, assigns fertility clinics licences to practive and audits success rates to ensure published data are accurate and honest.

IVF success rate statistics for all reputable clinics in the USA are found on the websites for the Centers for Disease Control and on the Society for Assisted Reproductive Technology (SART) website.

The Centers for Disease Control is a US Government agency. It publishes IVF success rates annually. The CDC  reports includes data on age, causes of infertility, number of embryos transferred, single and multiple births, etc.

The Society for Assisted Reproductive Technology (SART) also publishes annual reports for IVF including egg donor statistics.
