Our IVF Success Rates


Since its introduction in the year of 1970s, IVF success rates have increased by leaps and bounds in the IVF industry. From a mere low 10 over percent, it has now reached up to 80 over percent, through innovative treatment procedures and advanced technologies.

As a couple considering an IVF treatment, it is important to understand what success rates really mean in order to distinguish between clinical and individual success rates.

In general, success rate depends on variable factors such as :

Maternal Age
Cause of Infertility
Embryo Status
Reproductive History
Lifestyle Factors


Below are our IVF clinical pregnancy rates per embryo transfer based on all IVF treatments throughout 2019.

A clinical pregnancy is a pregnancy that is confirmed by both high levels of hCG (the pregnancy hormone) and ultrasound confirmation of a gestational sac or heartbeat , which is usually detected using a handheld Doppler .

As you can see from the table above, our frozen embryo transfer success rates are higher compared to fresh embryo transfer success rates.

With the deployment of the revolutionary Cryotec® freezing technology that ALPHA IVF has been using since 2013, it is evident that IVF treatments performed along with frozen embryo transfer is a more of an effective means of treatment, and thus an ideal choice to make. Pregnancy success rates are relatively higher for patients who have undergone Preimplantation Genetic Testing for Aneuploidies (PGT-A) to enable the selection of chromosomally normal embryo for transfer, than those without PGT-A.

Do note that individual results may vary with individual circumstances, and not every treatment cycle will result in an egg collection, an embryo transfer or embryo cryopreservation.


Revolutionary technologies that have been introduced in IVF play an important role in affecting IVF success rates. In being a patient of ALPHA IVF, you have access to the region’s leading innovative fertility treatment procedures and technologies that gives you IVF success rates that are comparable to top IVF centres worldwide.

The following outlines our published IVF success rates in 4 categories –

  • Blastocyst Transfer Program
  • IVF with and without PGS
  • Frozen Embryo Transfer Program (FET)

Blastocyst Transfer Program

Fresh blastocyst transfer at ALPHA IVF yields high clinical pregnancy and implantation rates and avoids higher order multiple pregnancies. The table below shows a review of ALPHA IVF’s Blastocyst Transfer Program*.

Fresh blastocyst transfer from day 5 – 6, Non PGS, ICSI Mean number of blastocysts transferred is 2.0

IVF with and without Preimplantation Genetic Screening (PGS)

IVF failure is often due to unknowingly transferring embryos which are chromosomally abnormal. By applying PGT-A or previously known as PGS, only embryos with the correct number of chromosomes (euploid) are transferred, hence improving pregnancy rates.

The graphs below show the clinical pregnancy rates for patients with and without PGS*.

World Class Success Rate Up To 82.9%*

We also demonstrated that transfer of a single good graded euploid blastocyst produces pregnancy rates as high as 82.9%.
