Okay in early morning of day 2, we check if the little babies started to divide, this is a good sign as the human being is consisted from divided hundred of cells who are responsible to create the parts of the baby body, arms, legs, Brian, etc.
So we get very excited to see embryos dividing. Now embryos are suppose to divide into 2 to 4 cells. Any division within this, we are happy with. Now when it comes to grade the embryo quality and give it a score, we have to bare in minds few things such as cells fragmentation and irregular divisions and granular or ugly embryos. What does this means to you as a patients?
Last thing for Day 2 is to call our patients and inform them with the news and give them the instructions for the next day. Not to mention if we have only 2 embryos and they are dividing we might put them back on day 2 depending on history and other factors.
Now lets talk about day 3 and there is a lot of action happens in this day. Now day 3 is very important as the babies will tell us how they are doing and if they like to go back to the uterus or they like to hang out with us for more few days. Basically, the babies talk to us. Here we go, we come in the morning as usually nice and early we start the warm little box for the babies warm and cozy and bring them over and start assessing the. Now day 3. Babies are suppose reached 6 to 8 cells so we been growing these babies for three days now, looking after them, feeding them so hopefully we been looking after them very carefully aiming to have excellent quality, this is always our aim. Another question pop out to how do we try to have good quality embryos? The answer is simple we make sure the babies always warm as the body temperature, we do not expose it unnecessary and when we do expose them outside their little home, we make sure they go to their little warm box that supplies gas to maintain temperature and PH, also we monitor our air quality by using special big filtered fan and be gentle when we handle them. Also its important how to prepare their dishes and tube set up that we use to move them from old solution to fresh one with new nutrients. We believe that this is extremely important step, not mention we aim to warm everything that get in touch with the babies and we use CE marked product as well. Hopefully that will help.
Okay thing gonna get more exciting when we come near the time to put the baby back to where they belong. Talking about day 5 then, day 5 is the last stage of baby development before they find their way to stick to mother womb. The babies decide we had enough far from mummy and its time to be with mummy. Now this is a very exciting moment but at the same time is the most critical moment as well. Replacing the babies back to the mother is very delicate, short and important step aiming for a full term baby. The clinician have to be on the top of his game and he know what he is doing, to know exactly where to go and how. So all the effort that we done so far frowning these babies do not go in vein. And believe me some they do not know what to do, that why you need to search carefully on which clinic to choose to go too. Always as an advice from you, always chase results. We are blessed in this country that we have a regulated body who publish the results for the whole country so you do not have to go so far in your research.
Anyway, the day 5 babies are called blastocysts, they liked to be called and treated differently. Now the formation of the blastocyst babies can happen on early morning of day 5 or late afternoon on the same day or they are a bit slow and they need one more day to reach their destination which is day 6. The question is does it matter day 5 or day 6 or is day 5 better than day 6 or day 6 is better, what is the story here?
The story is very simple, the babies will tell us when they are ready and it does not matter either day 5 or day 6 as long as we have blastocyst formation.
What does it mean blastocyst babies?
It means that or let me put it this way. Every year some of us go to ascot horse race and bet on which horse will win. Now if you ask me, all these beautiful horses look the same, beautiful and tall and strong ready to rock and roll but there is only and only one horse will when and that’s exactly how the babies behave on day 5 or day 6. So It’s a test for these beautiful babies and one or two will win to go back to mummy womb. At this point we hand over the babies to their mummies for another beautiful exciting journey hopefully will end in a full term babies.
Now not always things go smooth and nice, sometimes some babies are more hard work than others but we will do our best to get the job done.
Let’s go back to the decision making, after we assess the quality, we will have a look to the history as its extremely important step too. The history can tell us how the embryos behave by looking how did they do last cycle, the question is what does this means to you and your babies? The answer is if we see the babies did not develop after day 3 that is a sign for us to decide to consider day 3 vs day 5.
