Frozen Embryo Transfer.

We transfered two frozen embryos today. The quality varied a bit between the two. When blastocysts are frozen the collapse like raisins. When they are thawed and survive they reexpand like grapes. (Well, grapes don't actually reexpand, but you get the idea.)

One of the two was in the process of expanding at the time of the last check before the transfer. It had some ruptured cells, but that is expected in frozen embryos. The other one was still raisiny, but did have plenty live cells. The doctor told us that usually if they had only the one raisiny blast they wouldn't bother transferring it. Since we did have the fair one, though, we put back both.

Now we wait. The pregnancy test will be on the 17th, if I recall correctly. (It's been a long day.) We asked what our chances are, and after thinking about it a bit the doctor said we have a 20% shot. It's not that much, but a frozen transfer is a much less expensive and uncomfortable cycle, so it's a shot worth taking. If this doesn't work, I'm not sure what we'll try next. My wife may or may not feel up to doing another fresh cycle. Our contingency plan is to do IUI with donor sperm supplementing mine. Hopefully, though, we'll get pregnant this time and not have to worry about that.
