We create donor embryos only from donor eggs and sperm of the very best quality from professional, healthy, young donors.
We do not use embryos donated by patients which avoids passing problems with fertility on to your child.
In many other clinics, donated embryos from patients who have completed their fertility treatments are used in programmes of embryo adoption. However, the success rate is much lower owing to how old the genetic mother and father are and any problems with fertility they may have. Also, there is a risk that fertility problems could be passed on to your future child when IVF patients’ donor embryos are used.
We create donor embryos only from donor eggs and sperm of the very best quality from professional, healthy, young donors – we always have access to hundreds of these healthy, young egg and sperm donors. This will prevent transferring problems with fertility on to children at a later date, as can happen with IVF patients’ embryos. We can also give you the highest chance to become pregnant and have a live birth with a healthy baby.
IVF without ICSI permits natural selection of which sperm is going to be the one that fertilises the egg.
Through creating donor embryos using fresh donated egg and frozen/thawed donated sperm, fertilisation consistently happens via natural methods (just by combining the sperm and egg together). This method permits natural selection to take place to decide which sperm is going to be the one that fertilises the egg. This is different to other clinics that use patient donated embryos, these are often created through the ICSI process as a result of the genetic mother and father’s fertility problems.
The donated eggs that have been collected are then fertilised by the donated sperm are left to grow in our lab for 5 days. Throughout this period, they will divide and develop. When the embryos are 5 days old, they are called blastocysts. At this point it is possible to conclude which of the embryos are most likely to attach in the uterus.
Not all the good looking embryos have normal chromosome amount.
A wise man once said: “All that glitters is not gold”. Surprisingly, not all the good looking embryos are as promising as they may look. Some embryos which are good looking on day 5, but have internal problems will soon stop development and result in negative pregnancy test, or early miscarriage. These internal problems are most frequently caused by abnormal chromosome number in the embryo.
Good looking Embryos with abnormal chromosome amount do not result in a healthy baby.
Before a good looking blastocyst will become a part of our bank of embryos it will undergo comprehensive genetic testing for 23 chromosome pairs. Surprisingly 20-30% of these good looking donor blastocyst will have abnormal chromosome numbers and could have resulted in miscarriage or downs syndrome. Luckily, pre implantation genetic screening (PGS) allows us to exclude such abnormal embryos from usage.
Embryo for transfer is chosen on the basis of both good looks and normal chromosome count.
Clinical pregnancy rate is 60% with one embryo.
The best live birth rates per each embryo used are achieved if embryo for transfer is chosen on the basis of both good looks and normal chromosome count.
We only use top morphology blastocysts normal for 23 chromosomes which ensures not only high rates of implantation but also excellent live birth rates and low miscarriage rates.
We only use egg and sperm donors who are young and healthy which avoids passing problems with fertility on to your child at a later date, as well as giving you the maximum chance to have a live birth with a healthy baby.
