Embryo Cryopreservation

What is our method for cryopreservation?

We utilise a cryopreservation method from Japan to vitrify and thaw oocytes and embryos at any developmental stage. This method consistently achieves high post-thaw survival rates for embryos and blastocysts to maximise your clinical outcomes.

​One of the main advantages of cryopreserving embryos is to salvage all available embryos in a stimulated cycle. This means that these embryos can be opted for transfer in a later frozen cycle, increasing the chances of achieving pregnancy from a single egg retrieval. The additional benefits extend to the flexibility of preparing the uterus for optimal receptivity and by lowering the occurrence of OHSS.

The “freeze-all embryo strategy” is commonly implemented and is made possible by the efficient freeze-thaw survival rates by such vitrification systems.

Features of this cryopreservation method

  • ​​Consistent 99.9% survival of embryos and blastocysts when the protocol is strictly adhered to.
  • Minimal damage to oocytes or embryos ensuring that they are not adversely affected by the process of cryopreservation.
  • A simple and easy-to-learn protocol for trained embryologists. Our embryologists are trained and certified by the training division of the manufacturer to yield repeatable survival results.
  • Also effective to most eggs and embryos with poorer quality, such as eggs from older patients.​

 

Our experience

As part of the Alpha IVF Group which utilised this cryopreservation method since 2013, we observed 99.9% post-thaw survival rates for embryos and blastocysts.
