[The mouse test. Correlation between the segmentation of murine embryos and the fertilization and segmentation of human ovocytes and pre-embryos].

The "mouse test" resulted to be an indispensable requisite in order to do, with security, although not complete, the serum selection, to use in the extracorporal phase of FIVTE. Because of the observations it is considered that it should be tried to addition the culture medium with good quality sera; which is evident with a 90% rate, or more, of segmentation in the embryonic system of mouse, of two cells.
