Hi
I have a specific question, we are moving from our old clinic to put our embryos in temporary storage at another ivf clinic, until the appropriate clinic can be found. the receiving clinic what are their roles and duties as far as coordinating the move.
I know we need freezing protocols, and also hiv std, hepatitis testing, but should the receiving clinic tell the shipping clinic how to package the embryos and sperm on a straw, so all the receiving clinic has to do is take the embryos out and put in their storage tanks, bc each lab handles how they store embryos and sperm differently?


also on the blastocysts do you move the embryos into a different culture medium and incubator to make the embryos. is there a special incubator for 3 day embryos and a different incubator for a 5 day embryo?
and also do the culture mediums change on day 3 to try to take them to 5 day?

thanks for your input.

To the best of my knowledge, embryos are either frozen in straws or vials. It doesn't matter what container is used because the embryo container (straw or vial) is attached to a metal "cane" that makes identification and movement of the embryos from one tank (or clinic) to another much easier. Since this method of frozen embryo storage is universal, both the shipping and receiving clinics will know what to do. You won't have to do anything special.

For those programs using a sequential culture system, the composition of the culture medium used for Days 1-3 is different from the composition of the culture medium used for Days 3-5. Most programs use the same incubators throught the culture period.
