Embryo formation in Group D5 showed 46.7% (IVC) and 40% (IVF) of recovered
blastocysts. In the group D5, the conventional IVF, better embryo
development dynamics was observed, with 66% of expanded blastocysts, against
28% in the IVC. Group D3 showed 75% (IVC) and 53% (IVF) of embryo formation.
Embryonic quality in Group D3 demonstrated that IVF embryos had a better
synchrony in the number and quality of blastomeres. All embryos recovered in
Group D3, in both techniques, did not show fragmentation. The pH of the
medium contained in the INVOCell™ device in both Groups D5 and D3
showed no differences. The means were 7.26 and 7.25, respectively. The pH of
the medium used in IVF was 7.29 in both groups. Microbiological analyzes of
the culture media contained in the INVOCell™ devices used in Group D5
were negative.
