Menstrual cycle‐driven hormone concentrations co‐fluctuate with white and gray matter architecture changes across the whole brain

We performed multidimensional diffusion and T 1}‐weighted imaging of 30 women during three estimated phases of their menstrual cycles. Analyses revealed that 17β‐estradiol and LH were associated with increased microscopic FA, FSH and progesterone had opposing relationships with CT and mean diffusivity, and progesterone was associated with brain volume changes.
