Correlation between Human Embryo Morphokinetics Observed through Time-Lapse Incubator and Life Birth Rate.

(1)

Background

Does the variation in sequential development times of embryos, observed through time-lapse monitoring, between the two study groups play a role in predicting pregnancy success? (2)

Methods

The prospective double-arm study was to identify the morphokinetic parameters specific to embryos that were capable of implanting and were conducted on 89 embryos cultured in the Esco Miri time-lapse incubator, divided into two groups: Lot A, consisting of 57 embryos that successfully implanted and resulted in life birth rate (LBR), and Lot B (NLB), comprising 32 embryos that did not implant, leading to a negative beta-hCG outcome. (3)

Results

Baseline characteristics, including female age, were not found to be statistically significant (p > 0.01). In contrast, there is a highly statistically significant difference concerning oocytes (p = 0.0029). Morphokinetic variables represented by sequential culture times were not statistically significant (p > 0.01) when comparing the two groups. However, the negative mean differences between these parameters suggest that the times for Lot A are better (shorter) than those for Lot B. While not statistically significant, these differences may still have practical significance. In the case of grading, the difference is considered to be extremely statistically significant (p < 0.01). (4)

Conclusions

Although there are no statistically significant differences in sequential timings (p > 0.01) between the two groups, there are parameters indicating predictive potential for exploring pregnancy in embryo morphokinetics.
