Statistical analysis
Spermatozoa enrichment and PGT-A outcomes were compared between the ICSI/PGTA and ICSI/PGTA+GS groups using unpaired t-test (Stata Statistical Software, StataCorp LLC, College Station, TX). Friedman’s Chi-Square and Fisher’s Exact tests (Jandel Scientific, San Rafael, CA) were used to compare the ICSI cycle outcomes between the control and sex selection cohorts.
