WHAT ARE THE ADVANTAGES OF BLASTOCYST CULTURE ?
- The human body is the best incubator for human embryos but if there are several embryos to choose from on day 3, we know that not all will survive to day 5 whether they are in the laboratory or the womb. Keeping the embryos in the laboratory for these two extra days eliminates the possibility of transferring a (healthy-looking) embryo on day 3 which would naturally perish before day 5. Therefore it gives a better chance of transferring an embryo which will lead to a successful pregnancy and birth.
- The decision to choose a day 3 or day 5 embryo transfers will depend on the circumstances at the time. The embryologist will fully discuss this with the patient. We believe it is correct to proceed to day 5 wherever possible and do not believe that finance should play a part in this decision.
