Ghost: Morula vs Blatocyst

[toobee]

Can someone explain to me in more common terms the differance between Morula vs Blatocyst? I am an info junkie, I admit it- but its does tickle my brain and I would like to know one verse the other and the differance as I am headed towards a day 5 ET tommorrow - I have read woman saying they transferred both-

Morulae typically form on day 4. They are sometimes called "compacted" embryos, because the cells have formed into a tight huddle. The huddle analogy is a good one. Just as football players decide who will do what in the next play, the cells are deciding which of them will do what in the next developmental step.

That next step is blastocyst formation. The cells separate into two distinct formations. The cells that move to the outside edge of the blastocyst are called the trophectoderm, and will become the placenta if it implants. The cells that remain in a clump in the center are the inner cell mass, and this will become the fetus.

So a blastocyst has an inner cell mass (ICM), inside a sphere of trophectoderm of cells around the outer edge, and a cavity in between the two. This is much more complex than the morula stage (just a tight bunch of cells). This complexity gives us more information about the embryo, so we can grade it.

A few clinics like to grade and transfer morulae, but not many. There's just not much information to go on.

fascintaing- this stuff is amazing to me. When I think how many steps there are in human development it s amazing there are so many people in this world -

child birth is an amazing, so many intricate things have to happen

I just wanted to tell you of my experience. We transfered 3 morulaes on day 5. My RE said that they should be blastocysts on day 5, however mine only made it to morula stage. I am now 8 weeks pregnant with one baby. I have heard that morulas are better. I am not too sure of the reasoning, but it worked in my case. Good Luck.
