Menorrhagia was not associated with FSH (OR = 0.849, 95% CI = 0.712 – 1.013, p = 0.069), LH (OR = 1.021, 95% CI = 0.808 – 1.291, p = 0.860), prolactin (OR = 1.202, 95% CI = 0.984 – 1.469, p = 0.071), oestrogen (OR = 1.015, 95% CI = 0.988– 1.043, p = 0.279), or progesterone (OR = 0.951, 95% CI = 0.749 – 1.207, p = 0.678). This evidence concerns the gene BRD2 and Menorrhagia.
