| There were no significant differences in the distribution of embryos reaching to 2- cells, 4- cells, morula or blastocysts culturing on human endometrial stromal cells (Secretory or proliferative phases). The percent of morula in stage A (without fragmentation), stage B (<25% fragmentation), stage C (25-50% fragmentation) and stage D (>50% fragmentation) and did not showed significant differences between two coculture groups. Thus, the phase that the endometrial stromal cells were in thereby did not affect on the quality of embryos. |
