METHOD OF DETERMINATION IN VITRO OF PERSPECTIVE EMBRYONES FOR THE FOLLOWING IMPLANTATION IN THE UTERINE IN THE EXAMINATION OF THE EXTRACORPORAL FERTILIZATION PROCEDURE (EFP) Russian patent published in 2017 - IPC A61B17/435 A61B10/00 G01N33/483 

FIELD: medicine.

SUBSTANCE: to determine in vitro promising embryos for subsequent implantation into the uterus during the procedure of in vitro fertilization (IVF) by means of the time-lapse video recording in 2-cell embryos, the sequence and orientation of the planes of division (horizontal/equatorial E, vertical/meridional-M) of each blastomer. It is taken into account that such planes can be: successive equatorial (EE), successive meridional (MM), meridional, then equatorial (ME), equatorial, then meridional (EM). And if the sequences of divisions in these planes correspond to the variants (EM) or (MM), then such embryos are considered promising for subsequent implantation into the uterus during the IVF procedure.

EFFECT: early detection and transfer of the most promising embryos for implantation, which increases the frequency of implantation and pregnancy.
