“…There is e.g. a need for frequent observations to select the best in-vitro produced embryos for transfer, because better embryonic quality means higher chance for implantation and ultimately pregnancy [4][5][6]. In practice, the number of observations used in clinical IVF on human and animal embryos is therefore a compromise between a wish to keep the embryos undisturbed (with respect to light, temperature and pH) and to have as many observations as possible to facilitate optimal selection for transfer.…”

“…This has been recently confirmed in the SART register, with live-birth rates ranging from 44.9 to 34.9 or 21.3% using two good versus two fair or two poor embryos [18] . Accordingly, selection of the best embryo(s) to transfer is one of the most important steps in the IVF procedure and considerable efforts have been made to develop more accurate methods, either invasive or, preferably, non-invasive, by which to conduct this selection process.…”

“…Indeed, embryo morphology has long been known to be strongly associated with ART success rates [15][16][17] . This has recently been confirmed in a large multicenter trial, and the association was found to be independent of maternal age [18] . Pregnancy rates were found to be twofold higher with top quality (TQ) than poor quality embryos [18] .…”

“…Grading of day 3 embryos comprises cell number, degree of fragmentation, cell symmetry and presence or absence of cytoplasmic pitting, and has been shown to predict ART outcomes [1][2][3]. Better morphology grade embryos have been associated with significantly improved implantation rates and live birth rates [4,5].…”
