Title

COMPARATIVE ANALYSIS OF EMBRYO CLASSIFICATION BY KIDSCORE USING SEMINAL PARAMETERS

Objective

To evaluate seminal parameters according to stratified Kidscore groups.

Methods

A retrospective cohort study was performed in a Reproductive Medicine Center from January 2020 to December 2022. The embryos (n=3437) were cultivated in a time-lapse incubator (Embryoscope®, Vitrolife®) and were stratified into three groups according to Kidscore: G1 (1.0 - 4.0), G2 (4.1 - 7.0) and G3 (7.1 - 9.9). Male and seminal parameters (age, concentration, morphology and motility) were analyzed between groups. Frozen oocytes and preimplantation genetic testing (PGT) embryos were excluded as well as all the percutaneous epididymal sperm aspiration (PESA) and testicular sperm aspiration/extraction (TESA/TESE). The data were presented as mean and standard error (SE). ANCOVA test was applied, and data were adjusted for female age.

Results

The comparative analysis of seminal parameters between the three groups are shown in Table 1.

Conclusion

When the seminal parameters were compared according to the embryo score, no statistical difference was observed. Thus, in this study, seminal parameters seem not to have an impact on embryo quality evaluated through time lapse. More studies considering other variables should be performed for further conclusions regarding the male impact possibility on embryo quality.
