Morlula Stage Question

Post by Karling »

I had my ET yesterday and the 2 embryos they transfered were not at the blastocyst stage yet. They said they were Morlulas (sp????). Can anyone tell me more about this? What exactly does it mean? Are my chances that they will stick decreased because they wern't blasts yet? One was listed as a 5 (scale of 1-5, 5 being best) and one was a 3.

Thanks for the help!

After fertilization, embryos go through a stage called the cleavage stage. This is when the one cell spits to two, then to four, then to eight.

At the end of the cleavage stage, they enter a stage called compaction, as the cells join tightly with each other. they seem to be working out a plan, deciding which cells will perform which functions in the blastocyst stage.

An embryo in this compacted stage called a morula. (The plural is morulae, by the way.) Every embryo must go through this stage to be viable.

You probably had a day 5 transfer. A day 5 morula would probably become a day 6 blastocyst, so should have roughly the implantation rate of a day 6 blast. That's a little lower than for a day 5 blast. Of course it varies from one clinic to the next, but it should be somewhere near 30% per embryo.

Most clinics don't like to transfer morulae because they are more difficult to grade.
Avoid IVF and surrogacy in Ukraine. Ukrainian centers pay shills to post here under numerous sock accounts pretending to be patients in Ukraine. Centers using such deceptive advertising cannot be trusted and should be avoided.

This may be belated but I just wanted to offer a bit of information.
I had a day 5 transfer. We had decided on transfering 2 embryos because I'm young and healthy. Right before the transfer we were informed that the RE would like to transfer three because the quality was low, whereas they had all been "perfect" 2 days before. out of 11 mature eggs we were told we had one blast, two Morulea, and there would most likely be none surviving to freeze. We transfered the blast and two morulea. The next day they called to inform us that 3 had progressed to blast over night and were frozen. 9 day after transfer I recieved a positive beta and two weeks later an ultrasound showed twins :)
Those morulea are just a little slower to hop on the train! The lab technician that gave us all of our information regarding the embryos and cell division, etc. said that animal studies have led to a small amount of information indicating the possibility that slower dividing embryos are often times girls. I don't know anything about that for sure, but you definatly have a chance with them!
