I am always on the look out to learn something new and then turn around and share it with you. Below are a list of questions about Embryos in Hot Link form. I hope that you find the information as helpful as I did.

How are embryos graded? What is “normal development” for an embryo at the time of transfer? What is PGD? Is it possible to have genetic tests performed on embryos that have been frozen? Is it possible to tell the gender of an embryo? What is the typical success rate with frozen embryo transfer? When do embryos implant in the uterus? What are the symptoms of implantation? How soon can I take a pregnancy test? What factors can be used to assess the likelihood that an FET will be successful? Are children born from frozen embryos normal?

Nearly 400,000 embryos are stored in the United States,
88.2% are targeted for patient use, and
2.8% are available for research.
