A Visit To The Biologist

We visited the Biologist today regarding on how many embryos to transfer. We were asked how many children we want for our life. And my answer is 2 which mean we will do a Single Embryo Transfer (SET).

We will thaw 2 embryos and if 2 of them survive, the biologist will continue to culture (growing) the embryos for a few more days to see which one reach the late blastocyst stage. Blastocyst transfers can increase the chance of pregnancy per embryo, while decreasing the risk of multiple pregnancies. According to the Biologist, my six frozen embryos are considered as good grade (2 @ 8 cells & 4 @ 6 cells on Day Three) . *Phew*

A blastocyst is an embryo that has developed for five to seven days after fertilization. At this point the embryo has two different cell types and a central cavity. It has just started to differentiate. The surface cells, called the trophectoderm, will become the placenta, and the inner cells, called the inner cell mass, will become the fetus. A healthy blastocyst should begin hatching from its outer shell, called the zona pellucida by the end of the sixth day. Within about 24 hours after hatching, it should begin to implant into the lining of the mother's uterus.

A bit too much for you guys??? ^.^

I know doing a Single Embryo Transfer lowered the rate of my pregnancy but I really cannot imagine taking care of Shannon with newborn twins without any help over here. Moreover, raising 3 or 4 kids are no longer an easy task as compared to 10/20 years ago. I do not want to deprive my kids in anything they are or will be interested, but not able to participate or involve just because we are only earning enough to feed them. :P
