Quality of Embryos

Embryos are categorized into four major categories as follows:

Type 1: The cells of the embryo split evenly and the broken cell ratio does not exceed 10%.

Type 2: The cells of the embryo do not split evenly and the broken cell ratio does not exceed 25%.

Type 3: The cells of the embryo do not split evenly and the broken cell ratio exceeds 25%.

Type 4: The cells of the embryo do not split evenly and many cells are broken.

In regards to conception potential and those of a natural delivery, all are able to form normal fetuses but the chances of pregnancy with embryos of the first and second categories are greater. Chances of pregnancy with the first and second categories can be equal but the third and fourth categories have less of a chance, although not entirely impossible. Regarding congenital malformations, there is no proof that embryos of the third and fourth categories have a higher ratio of occurrence.


Embryo Transfer

Embryo transfer plays a critical role in making or breaking the treatment. Thus, no matter how good the status of embryos is and regardless of their quantity, if embryos are not transferred smoothly and accurately, all the financial, physical, and scientific efforts will be in vain. The Farah Hospital adopts special techniques for embryo transfer into the mother's uterus, it has also developed an exclusive tool, which is being used by centres worldwide. This tool increases percentages of success as a result of overcoming the difficulty of embryo transfer. We faced various cases in which embryo transfer was very difficult or near impossible, and was nonetheless achieved easily in our centre thanks to this tool.

It is worth mentioning that the embryo transfer stage is a great prognostic indicator to the overall state of the case. The actual process of embryo transfer lasts on average ten minutes and is similar to a speculum exam in the clinic. Usually no sedation is required. Afterwards, the wife can safely leave the hospital.


How Many Embryos To Transfer?

The decision regarding the number of transferred embryos lies with the couple, with the approval of the supervising team. For instance, the couple may request to transfer five or six embryos, or even more, to the mother's uterus. The unit does not advise or agree to such requests in fear that the mother will become pregnant with triplets or more, which would have negative repercussions. The number of embryos advised for transfer depends on the following factors:

  • The mother's age.
  • Previous trials the mother has undergone.
  • Was the mother pregnant previously? And did she reach her term?
  • Has the mother miscarried previously? At which stage of pregnancy did the miscarriage happen?
  • The mother and father's desire concerning the number of transferred embryos.
  • The couple's approval to decrease the number of embryos if multiple twin pregnancies occur.
  • Number of available embryos and their quality. The uterus's shape.
  • The mother's health; Does she suffer from any complications such as blood pressure, diabetes, etc...?

The Farah Hospital prefers single child pregnancies, as they possess many advantages for both mother and child. Pregnancy of three or more babies is not advised as it may affect both mother and fetuses negatively. Before proceeding with the transfer, embryos are checked closely to determine quantity and quality, and parents are advised accordingly on the number of embryos preferred to be transferred to the mother's uterus. The previous mentioned factors are taken into consideration.

In conclusion, we warn the couple from insisting on transferring many embryos, for this has many negative effects. If it results in multiple pregnancies, The Farah Hospital's team is delighted to discuss this with concerned parents at their discretion.


The Fate Of Transferred Embryos

Some mistakenly think that if the embryos are transferred to the mother's uterus then conception had occurred or is about to occur. This of course is the wish of both the couple and the team, but unfortunately, pregnancy does not always happen. Success ratios depend on many factors some of which are the quality of embryos, the type of uterus and the nature of its endometrium (inner lining of uterus where embryos implant), and of course how facilitated the transfer process to the uterus was, and whether the mother had conceived previously.

The greatest moments for the team are when good news are brought to the couple of positive lab tests and the gift of conception, we often hear 'Zaghareed' and sounds of joy over the phone or feel the tears of joy when the wife receives the joyful news. Other times, we are forced to give bad news, where some people thank God for everything and make another appointment to study what happened and what can be done in the future. But a few are frustrated to receive the news and condemn the failure which emotionally affects all parties concerned. Thus we kindly ask the couple to have patience if the attempt was not successful. In fact, embryo transfer is a great prognostic indicator and the success rate increase upon repetition to about 90%, consequently, we ask the unfortunate couple to be optimistic and patient and book another appointment to discuss what can be done in the future. Failing a trial does not mean the loss of information retained, but to the contrary, can be invaluable information to be used for future attempts.


Surplus Embryos

The Farah Hospital seeks to offer medical services of the highest international standards for its patients. We are often faced with the issue of surplus embryos, at which point The Farah Hospital's team is ready to advise the couple: What should we do with these surplus embryos? Would you prefer freezing them? The advice depends on the number of embryos, their category, and location of the couple's residence. If surplus embryos were from first or second category cells, we advise the couple to resort to freezing. But, if surplus embryos are of the third or fourth category, we don't recommend freezing, as embryos won't tolerate the freezing process.

The Farah Hospital's team is delighted to discuss the matter with the couple if such a need arises, and we are glad to answer any inquiry.
