For the first IVF cycle, GnRH-antagonists demonstrated higher CLBR per aspiration than the first MOS on both, univariate analysis (12.92 versus 4.54%, crude OR 3.117; 95% CI 1.737, 5.592, p < 0.001) and multivariate analysis after adjusting for female age, body mass index, basal FSH, basal E2, infertility years, and primary infertility (vs. secondary infertility) (adjusted OR 2.606; 95% CI 1.386, 4.899, p = 0.003). Here, BRD2 is linked to Infertility.
