BRD2 and Infertility: Similarly, in the ≥ 35 years age group, compared with poor-quality blastocysts (50/205), good-quality blastocysts (18/43) (41.86% vs. 24.39%; OR 2.131, 95% CI 1.071–4.242; P = 0.048) and average-quality blastocysts (42/92) (45.65% vs. 24.39%; OR 2.722, 95% CI 1.566–4.732; P = 0.003) had significantly higher euploidy rates after adjusting for developmental rate, maternal age, maternal BMI, duration of infertility, type of infertility, infertility diagnosis, number of prior pregnancies, indication for PGT-A and basal FSH.
